Caliper and Brake Lines

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, 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.
