Diagram ref no 11

Although small, this connection piece forms an important part of the hydraulic braking system. A secure, correctly sealed connection helps maintain brake fluid pressure between the rigid brake pipe and associated hydraulic components.

What Does the Brake Hose / Line Connection Piece Do?

The connection piece provides a secure joining point within the vehicle's hydraulic brake circuit.

When the brake pedal is pressed, hydraulic pressure generated by the master cylinder must travel through the brake pipes and flexible hoses to the brake calipers or wheel cylinders. Every connection within this system must remain securely sealed to prevent loss of brake fluid and hydraulic pressure.

Why Is It Important?

The braking system relies on a closed hydraulic circuit. Even a relatively small leak at a brake line connection can result in fluid loss and reduced braking effectiveness.

A correctly fitted connection piece helps:

• Provide a secure brake hose/line connection
• Maintain the integrity of the hydraulic brake circuit
• Prevent brake fluid leakage at the joint
• Maintain correct factory brake line routing
• Provide the correct connection when replacing brake pipes or hoses
• Restore the original brake system during a classic Porsche restoration

Because it forms part of a safety-critical hydraulic system, the fitting and surrounding brake lines should always be inspected carefully during brake servicing.

Why Does It Fail?

Metal brake fittings can deteriorate after decades of service, particularly on classic Porsche models exposed to moisture, road dirt and road salt.

Common problems include:

• External corrosion
• Damaged or rounded threads
• Seized brake pipe fittings
• Damage during removal of old brake hoses or pipes
• Distorted sealing surfaces
• Previous overtightening
• Cross-threading
• Contamination around the connection
• General deterioration associated with age

Older fittings can also become extremely difficult to separate from the brake pipe after many years in position. Attempting to force a seized connection may damage the fitting or adjoining brake line.

When Should It Be Replaced?

Replacement should be considered if the connection piece is corroded, damaged, seized or no longer provides a reliable hydraulic connection.

It is also sensible to inspect and, where necessary, replace the fitting when installing:

• New brake hoses
• Replacement rigid brake pipes
• New brake calipers
• Refurbished brake calipers
• A replacement master cylinder
• A completely restored braking system

Any evidence of brake fluid leakage around the connection requires immediate investigation.

Checks and Diagnosis

Before replacing the connection piece, inspect the surrounding braking system carefully.

Check the rigid brake pipe for corrosion or damage and inspect the flexible hose for cracking, swelling, abrasion or deterioration. Check the threads and sealing surfaces of all mating components and look for signs of brake fluid leakage.

If the brake pedal feels unusually soft or requires excessive travel, the complete hydraulic system should be checked rather than assuming the connection piece itself is responsible.

After opening the hydraulic circuit, the brake system must be correctly bled and checked for leaks before the vehicle is returned to use.

Brake Line Kit, 1 Circuit Brake System (Not For Models With Brake Booster).

The OE Match Brake Line Kit is a complete replacement hard brake pipe set for early Porsche 911 models with a single-circuit braking system and without a brake booster.
Set Of 9.

NOTE: Needs To Be Moulded Into Shape!

Fits:

The kit contains 9 brake lines required to renew the vehicle's rigid hydraulic brake pipework. These lines carry pressurised brake fluid from the master cylinder through the braking circuit to the wheel brakes.

Designed for left-hand-drive Porsche 911 models from 01/1963 to 07/1967, the pipes are supplied ready to be carefully formed and routed to match the original installation.

This kit is particularly suitable for restoration projects or for replacing original brake pipes that have become corroded, damaged or unsafe through age.

What This Product Does:
Brake lines are an essential part of the vehicle's hydraulic braking system.

When the brake pedal is pressed, the master cylinder generates hydraulic pressure in the brake fluid. The rigid brake lines carry this pressure through the vehicle to the braking components at each wheel.

The brake line system therefore helps:

• Transfer hydraulic pressure from the master cylinder to the brakes
• Provide consistent braking response
• Maintain a sealed hydraulic circuit
• Prevent loss of brake fluid
• Support reliable operation of the braking system
• Maintain the correct routing of brake fluid around the vehicle

Because this application uses a single-circuit braking system, maintaining the integrity of every brake pipe is especially important.

Symptoms Of Wear Or Failure:
Brake pipes are exposed to moisture, road contamination, vibration and corrosion throughout the life of the vehicle.

Common signs that brake lines may require replacement include:

• Visible rust or corrosion on the pipes
• Heavy pitting of the metal surface
• Flaking or weakened pipework
• Dampness or brake fluid around a pipe
• Brake fluid leaking from unions or damaged sections
• Falling brake fluid level
• Soft or spongy brake pedal
• Pedal travelling further than normal
• Reduced braking performance
• Brake warning symptoms associated with fluid loss
• Damaged, crushed or incorrectly bent brake lines
• Corroded pipe unions that can no longer be serviced reliably
• Brake pipes identified as unsafe during inspection or restoration

Any evidence of leaking or severely corroded brake pipework should be treated as a safety-critical issue.

Why Replacement Matters:

• Brake lines must withstand considerable hydraulic pressure every time the brakes are applied.
• Corrosion gradually reduces the wall thickness of a steel brake pipe. If deterioration becomes severe, the pipe can begin to leak or may rupture when the braking system is pressurised.
• A brake fluid leak reduces hydraulic pressure and can cause a substantial loss of braking performance. This is particularly significant on a single-circuit system, where a major hydraulic failure can affect the braking system much more extensively than on later dual-circuit arrangements.
• Replacing ageing brake pipes before they fail helps restore the integrity of the hydraulic circuit and ensures braking pressure can be transmitted safely to the wheel brakes.
• A complete line kit is also useful during a full restoration, allowing multiple decades-old pipes to be renewed together rather than retaining potentially weakened original sections.

Installation: Requires hand forming

This 10-piece rigid brake pipe set is designed for early Porsche 911 models equipped with a single-circuit hydraulic braking system.

Ideal for replacing corroded, damaged or ageing original brake pipes, the kit helps restore the reliability and safety of the braking system while maintaining an original-style installation.

What Does the Brake Line Kit Do?

The rigid brake pipes carry pressurised brake fluid from the master cylinder through the hydraulic braking system.

They provide the essential connections required to operate the brakes, helping maintain consistent hydraulic pressure and reliable braking performance.

Why Do Brake Lines Fail?

Over time, exposure to moisture, road salt and general ageing can cause corrosion and deterioration of the original metal pipes.

Common problems include:

Rust and corrosion along the brake pipes Damage from road debris or incorrect installation Deterioration around pipe unions and connections Brake fluid leaks caused by weakened or damaged pipes

When Should They Be Replaced?

Brake lines should be replaced when inspection reveals significant corrosion, damage, leaks or weakened sections.

Replacement is also recommended during a complete braking system overhaul or classic Porsche restoration, particularly when the condition of the original pipes is uncertain.

Confirm the original braking system and pipe arrangement before ordering.

Installation Notes

The brake pipes require careful forming to follow the original routing and must be installed using the correct fittings and connections.

Professional installation is recommended. Once fitted, the braking system must be correctly bled, pressure-tested and checked for leaks before driving.

Porsche 911 SWB Brake Lines & Hydraulic Brake System Restoration Parts

The rigid brake lines are essential components of the early Porsche 911 hydraulic braking system, transferring brake fluid pressure from the master cylinder to the wheel brakes.

Brake Line Kit, 1 Circuit Brake System (Not For Models With Brake Booster).

The OE Match Brake Line Kit is a complete replacement hard brake pipe set designed for early Porsche models equipped with a single-circuit braking system and without a brake booster.
Set Of 9.

NOTE: Needs To Be Moulded Into Shape!

Fits:

• Porsche 911 1967-1968 2.0L / 912 SWB (F) (LHD Cars)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F) (LHD Cars)

The kit contains 9 brake lines used to renew the rigid hydraulic pipework that carries brake fluid from the master cylinder to the braking components around the vehicle.

Designed for early left-hand-drive applications, the pipes are supplied ready to be carefully formed and routed to match the original installation. This makes the kit particularly suitable for restoration work or replacement of original brake lines that have become corroded, damaged or unsafe through age.

What This Product Does:
The brake lines form a vital part of the vehicle's hydraulic braking system.

When the brake pedal is pressed, the master cylinder creates hydraulic pressure in the brake fluid. The rigid brake pipes transfer this pressure through the vehicle to the brakes at each wheel.

Their main functions include:

• Carrying pressurised brake fluid through the braking system
• Transferring hydraulic force from the master cylinder to the wheel brakes
• Maintaining a sealed hydraulic circuit
• Supporting consistent and predictable braking
• Preventing brake fluid loss
• Maintaining the correct factory routing of the braking system
• Providing reliable hydraulic connections between braking components

Because this vehicle uses a single-circuit brake system, maintaining the integrity of the complete hydraulic circuit is particularly important.

Symptoms Of Wear Or Failure:
Steel brake pipes are exposed to moisture, road dirt, salt, vibration and repeated temperature changes. Over time, they can corrode or become mechanically damaged.

Common signs that brake pipes may require replacement include:

• Visible surface rust or corrosion
• Heavy pitting of the metal pipework
• Flaking or weakened sections of pipe
• Brake fluid leaking from a pipe or union
• Damp or oily-looking areas around brake connections
• Falling brake fluid level
• Soft or spongy brake pedal
• Increased brake pedal travel
• Reduced braking performance
• Brake pedal gradually sinking under pressure
• Damaged, kinked or crushed brake pipes
• Corroded fittings that can no longer be serviced safely
• Brake pipes flagged as unsafe during inspection
• Deterioration discovered during restoration work

Any leaking or heavily corroded brake line should be treated as a safety-critical fault.

Why Replacement Matters:

• Brake lines must withstand substantial hydraulic pressure every time the brakes are applied.
• Corrosion gradually reduces the wall thickness of the metal pipe. If deterioration progresses far enough, the line may begin to leak or can rupture when the brakes are applied.
• A loss of brake fluid reduces hydraulic pressure and can cause a serious reduction in braking performance. This is particularly significant on a single-circuit system, because one major hydraulic failure can affect the braking system much more extensively than on later dual-circuit designs.
• Replacing deteriorated brake lines before they fail helps restore the integrity of the braking circuit and ensures hydraulic pressure can be transmitted safely to the brakes.
• Renewing the complete set during a restoration is also beneficial because it avoids retaining other ageing sections of original brake pipe that may be approaching the same level of deterioration.

Brake Line Kit 1 Circuit Brake System (Not For Models With Brake Booster).

The OE Match Brake Line Kit is a complete 10-piece rigid brake pipe set designed for selected early left-hand-drive Porsche 911 models equipped with a dual-circuit braking system without a brake booster / servo.
Set Of 10.

NOTE: Needs To Be Moulded Into Shape

Fits:

• Porsche 911 2.0-2.2 08/68-07/71 LHD Cars

The rigid brake lines form the hydraulic connection between the master cylinder and the vehicle's wheel braking components. When the brake pedal is pressed, hydraulic pressure generated by the master cylinder travels through these pipes, allowing the braking system to apply the brakes at each wheel.

Over decades of use, original steel brake pipes can suffer from corrosion, external damage, seized unions or internal contamination. Because brake lines carry pressurised brake fluid and form a safety-critical part of the braking system, pipes showing significant deterioration should be replaced rather than relied upon indefinitely.

This kit provides the principal rigid brake pipes required to renew the system using correctly specified replacement lines.

What This Product Does:
The rigid brake pipes carry hydraulic brake fluid under pressure throughout the braking system.

The kit is designed to:

• Transfer hydraulic pressure from the master cylinder.
• Deliver brake fluid to the front and rear braking circuits.
• Maintain a sealed hydraulic connection between braking components.
• Support simultaneous and predictable braking operation.
• Replace corroded or damaged original steel brake lines.
• Restore the integrity of an ageing hydraulic braking system.
• Provide replacement pipes for a full brake-system restoration.
• Help eliminate leaks caused by deteriorated brake pipes.
• Restore correctly routed hydraulic connections.
• Support safe and consistent brake operation.

Because the vehicle uses a dual-circuit system, the hydraulic system is divided into separate circuits to provide additional braking-system redundancy compared with an earlier single-circuit arrangement.

Symptoms Of Wear Or Failure:
Possible signs of brake line deterioration include:

• Visible rust on the steel pipes.
• Heavy corrosion or pitting.
• Flaking metal around the brake pipe.
• Dampness around pipe unions.
• Brake fluid visible on the pipe surface.
• Brake fluid dripping beneath the vehicle.
• Falling brake fluid reservoir level.
• Soft or spongy brake pedal.
• Brake pedal travelling farther than normal.
• Reduced braking performance.
• Brake pedal slowly sinking under constant pressure.
• Uneven braking.
• Brake warning light illuminating where applicable.
• Corroded or seized pipe unions.
• Crushed or kinked brake lines.
• Abrasion where pipes contact the body or other components.
• Damage resulting from previous repairs or underbody impact.

A brake fluid leak should always be investigated immediately.

Why Replacement Matters:
Brake lines operate under considerable hydraulic pressure whenever the brakes are applied.

Corrosion gradually reduces the thickness and strength of a steel pipe. A line that appears only moderately rusty externally may be substantially weakened if corrosion is deep or concentrated around clips, bends and unions.

Replacing deteriorated brake lines helps restore:

• Hydraulic-system integrity.
• Reliable brake-fluid containment.
• Consistent braking pressure.
• Correct pedal feel.
• Reliable operation of both brake circuits.
• Long-term braking-system safety.
• Confidence during a complete restoration.

Brake Line Kit, 2 Circuit Brake System (Not For Models With Brake Booster).
The OE Match Brake Line Kit is a complete replacement hard brake pipe set for classic Porsche 911 models equipped with a dual-circuit braking system and without a brake booster.
Set Of 10.

NOTE: Needs To Be Moulded Into Shape!

Fits:

The kit contains 10 rigid brake lines used to renew the hydraulic pipework that carries pressurised brake fluid between the master cylinder and the braking components around the vehicle.

Designed for left-hand-drive Porsche 911 models from 08/1971 to 07/1973, the lines are supplied ready to be carefully shaped and routed to match the original installation.

This kit is particularly suitable for restoration work, major brake-system refurbishment, or replacement of original steel brake pipes that have become corroded, damaged or unsafe through age.

What This Product Does:
The brake lines form a critical part of the vehicle's hydraulic braking system.

When the brake pedal is pressed, the master cylinder generates hydraulic pressure. The rigid brake pipes carry this pressurised fluid through the vehicle to the wheel brakes, allowing braking force to be applied.

Their main functions include:

• Carrying pressurised brake fluid through the vehicle
• Transferring hydraulic pressure from the master cylinder to the wheel brakes
• Maintaining a sealed braking circuit
• Supporting consistent brake pedal response
• Preventing brake fluid loss
• Maintaining correct hydraulic connections between braking components
• Helping preserve the original brake-line routing
• Supporting reliable operation of the dual-circuit braking system

A dual-circuit brake system divides the hydraulic system into separate circuits, providing an additional level of redundancy compared with an earlier single-circuit arrangement.

Symptoms Of Wear Or Failure:
Rigid brake lines are exposed to moisture, road salt, dirt, vibration and repeated temperature changes. Over many years, steel pipes can corrode or become physically damaged.

Common signs that brake lines may require replacement include:

• Visible rust or corrosion
• Heavy surface pitting
• Flaking or severely deteriorated pipe surfaces
• Brake fluid leaking from a pipe
• Wetness around brake-line unions
• Falling brake fluid reservoir level
• Soft or spongy brake pedal
• Increased brake pedal travel
• Brake pedal slowly sinking under pressure
• Reduced braking performance
• Brake warning indications
• Damaged or rounded pipe fittings
• Bent, crushed or kinked brake lines
• Pipes rubbing against surrounding components
• Severe corrosion around retaining clips
• Poor-quality previous brake-line repairs
• Pipes identified as unsafe during inspection or restoration

Any leaking or heavily corroded brake pipe should be treated as a safety-critical fault.

Why Replacement Matters:
Brake lines must contain substantial hydraulic pressure every time the brakes are applied.

Corrosion gradually reduces the wall thickness of a steel brake pipe. If deterioration progresses far enough, the line can begin to leak or may rupture under braking pressure.

Loss of brake fluid reduces hydraulic pressure and can seriously compromise braking performance. Although a dual-circuit system provides more redundancy than a single-circuit design, failure of one circuit still causes a significant reduction in braking capability and requires immediate repair.

Replacing ageing or corroded brake lines helps restore:

• A sealed hydraulic braking system
• Reliable transmission of brake pressure
• Consistent pedal feel
• Correct operation of both brake circuits
• Reduced risk of brake-fluid loss
• Safer and more predictable braking

For restoration projects, replacing the complete pipe set is often preferable to renewing only one visibly damaged section, as other original lines may be of similar age and condition.
