Product Information
Brake Line Kit 1 Circuit Brake System.

The OE Match Brake Line Kit is a complete 8-piece rigid brake pipe set for selected Porsche 356 B T5 1.6 models with a single-circuit braking system.
SET OF 8.

NOTE: Needs To Be Moulded Into Shape!

Fits:
  • Porsche 356 B T5 1.6 01/59-07/62 (LHD Cars)

Designed for left-hand-drive vehicles, the kit replaces the ageing steel hydraulic brake pipes that carry brake fluid between the master cylinder and the wheel braking components.

The pipes are supplied in a form that requires bending and moulding into the correct vehicle-specific shape during installation. They are therefore intended to follow the original Porsche routing once formed and fitted correctly.

What This Product Does:
The rigid brake lines carry pressurised brake fluid through the vehicle's hydraulic braking system.

When the driver presses the brake pedal, the master cylinder creates hydraulic pressure. The brake lines transfer this pressure to the braking components at the wheels.

Their primary functions are to:

  • Carry brake fluid under hydraulic pressure
  • Transfer braking force from the master cylinder
  • Connect the main sections of the braking system
  • Maintain a sealed hydraulic circuit
  • Allow the wheel brakes to operate simultaneously
  • Preserve reliable brake pedal response

Without sound, leak-free brake lines, hydraulic pressure cannot be transmitted correctly through the system.

Symptoms Of Wear Or Failure:
Possible signs of deteriorating brake lines include:

  • Visible surface corrosion
  • Heavy rust
  • Pitting
  • Wet brake pipes
  • Brake fluid around unions
  • Brake fluid loss
  • Soft brake pedal
  • Spongy pedal feel
  • Pedal gradually sinking
  • Increased pedal travel
  • Reduced braking performance
  • Brake warning symptoms following fluid loss
  • Fluid collecting under the vehicle
  • Corroded pipe unions
  • Crushed or kinked brake pipes
  • Damaged protective surfaces
  • Pipes rubbing against the body or suspension

Any visible brake-fluid leakage should be treated as a serious braking-system fault.

Why Replacement Matters:
Brake pipes are safety-critical hydraulic components.

Continuing to use heavily corroded or leaking lines can result in:

  • Loss of brake fluid
  • Reduced hydraulic pressure
  • Longer stopping distances
  • Poor pedal response
  • Sudden brake-line rupture
  • Severe loss of braking performance

The risk is especially important on a single-circuit system, where one significant leak can affect the braking system as a whole.

Replacing ageing pipes restores the integrity of the hydraulic circuit and provides a sound foundation for correct brake operation.

Brake Line Kit 1 Circuit Brake System.

The OE Match Brake Line Kit is a complete 8-piece rigid hydraulic brake pipe set for selected Porsche 356 B T6 1.6 models with a single-circuit braking system.
SET OF 8.

NOTE: Needs To Be Moulded Into Shape

Fits:
  • Porsche 356 B T6 1.6 08/62-12/63 (LHD Cars)

Designed for left-hand-drive vehicles, the kit replaces the ageing rigid brake pipes that carry pressurised brake fluid from the master cylinder through the vehicle to the wheel braking components.

The pipes are supplied requiring final bending and shaping during installation, allowing them to follow the original factory routing once correctly formed.

What This Product Does:

The rigid brake pipes form the fixed hydraulic network of the braking system.

When the brake pedal is pressed, the master cylinder generates hydraulic pressure. The brake lines transmit this pressure to the braking components at the wheels.

Their functions include:

  • Carrying brake fluid under pressure
  • Transferring braking force from the master cylinder
  • Connecting the different sections of the hydraulic brake system
  • Maintaining a sealed hydraulic circuit
  • Supporting consistent brake operation at each wheel
  • Providing a rigid connection between flexible brake hose sections and other brake components

Without sound and leak-free brake lines, the hydraulic braking system cannot operate correctly.

Symptoms Of Wear Or Failure:
Signs that rigid brake pipes may require replacement include:

  • Visible rust or corrosion
  • Deep pitting
  • Flaking metal
  • Brake fluid around pipework
  • Wet unions or connections
  • Falling brake-fluid level
  • Soft or spongy brake pedal
  • Pedal travelling farther than normal
  • Pedal slowly sinking under pressure
  • Reduced braking performance
  • Damaged or crushed pipe sections
  • Kinked brake lines
  • Corroded union fittings
  • Pipes rubbing against the chassis or suspension
  • Damaged protective surfaces
  • Visible fluid beneath the vehicle

Any hydraulic brake-fluid leak should be treated as a serious fault.

Why Replacement Matters:
Brake pipes are safety-critical components.

Continued use of badly corroded or damaged lines can lead to:

  • Sudden pipe rupture
  • Brake-fluid loss
  • Reduced hydraulic pressure
  • Excessive pedal travel
  • Increased stopping distance
  • Severe loss of braking performance

This risk is especially important on a single-circuit brake system, where one major hydraulic failure can affect the system as a whole.

Replacing deteriorated pipes restores the integrity of the hydraulic circuit.

Product Information
Brake Line Kit 1 Circuit Brake System.

The OE Match Brake Line Kit is a complete 8-piece rigid hydraulic brake pipe set for selected Porsche 356 C 1.6 models with a single-circuit braking system.
SET OF 8.

Fits:
  • Porsche 356 C 1.6 01/63-12/65 (LHD Cars)

Designed for left-hand-drive vehicles, the kit replaces the ageing steel brake pipes that carry hydraulic brake fluid between the master cylinder and the wheel braking components.

The set also includes two steel caliper bridge pipes, making it a comprehensive replacement package for the rigid brake pipework used on the 356 C braking system. Selected sections incorporate close-fitting vinyl protection to help reduce damage from stones, debris and road contamination.

What This Product Does:
The rigid brake lines carry pressurised brake fluid through the braking system.

When the driver presses the brake pedal:

  • The master cylinder creates hydraulic pressure
  • Brake fluid is forced through the rigid lines
  • Pressure is transmitted to the wheel braking components
  • The brakes apply and slow the vehicle

The brake lines therefore form the fixed hydraulic network connecting the master cylinder with the front and rear braking assemblies.

Their primary functions include:

  • Carrying brake fluid under pressure
  • Transferring hydraulic braking force
  • Maintaining a sealed braking circuit
  • Connecting the master cylinder to the wheel brakes
  • Supporting consistent brake operation
  • Providing rigid connections between flexible hose sections and calipers

Symptoms Of Wear Or Failure:
Common signs that rigid brake pipes may require replacement include:

  • Surface corrosion
  • Heavy rust
  • Deep pitting
  • Flaking metal
  • Brake-fluid leakage
  • Wet unions
  • Falling fluid level
  • Soft brake pedal
  • Spongy pedal feel
  • Increased pedal travel
  • Pedal sinking under pressure
  • Reduced braking performance
  • Damaged or crushed lines
  • Kinked pipework
  • Corroded fittings
  • Pipes rubbing against the chassis
  • Fluid collecting beneath the vehicle

Any visible brake-fluid leak should be treated as a significant braking-system fault.

Why Replacement Matters:
Brake lines are safety-critical components.

Continued use of severely corroded or damaged pipes can result in:

  • Brake-fluid loss
  • Reduced hydraulic pressure
  • Excessive pedal travel
  • Longer stopping distances
  • Sudden line rupture
  • Severe loss of braking performance

The risk is especially important on a single-circuit system, where a major leak can affect the braking system as a whole.

Replacing deteriorated pipes restores the integrity of the hydraulic circuit.

Brake Line Rubber Grommet.

The OE Match Brake Line Rubber Grommet is a replacement protective sleeve used where the vehicle’s rigid brake pipe passes through bodywork or bulkhead openings.
Sold Each.
x2 Required Per Car.

Fits:
  • Porsche 356 B/C 1.6-2.0 01/59-12/65
  • Porsche 911 2.0-3.3 01/63-07/89
  • Porsche 912 1.6 01/65-02/70
  • Porsche 914 1.7-2.0 01/69-02/76
  • Porsche 959 2.8 01/86-04/91

Its job is simple but important: the rubber grommet separates the metal brake line from the surrounding metal panel, helping prevent direct contact, vibration, abrasion and chafing.

Without an effective grommet, normal vehicle movement and vibration can allow the brake pipe to rub against the edge of the body opening. Over time, this can damage the protective coating on the pipe and potentially wear into the brake line itself.

Replacing hardened, cracked, missing or damaged grommets helps preserve the condition of the hydraulic brake pipe and supports long-term braking-system reliability.

What This Product Does:
The brake line grommet protects the rigid hydraulic brake pipe where it passes through the vehicle body.

It is designed to:

  • Prevent direct metal-to-metal contact between the brake pipe and bodywork.
  • Cushion the brake line inside the body opening.
  • Reduce vibration transmitted into the pipe.
  • Help prevent brake-line chafing.
  • Protect the brake pipe coating from abrasion.
  • Help maintain correct positioning of the brake line.
  • Reduce movement where the pipe passes through bulkheads or panels.
  • Replace a hardened, cracked or missing original grommet.
  • Support long-term hydraulic brake-line integrity.

Although small, the grommet performs an important protective function in a safety-critical braking system.

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

  • Rubber becoming hard or brittle.
  • Visible cracking.
  • Splitting around the centre opening.
  • Grommet becoming loose in the body panel.
  • Grommet partially pulling out of its mounting hole.
  • Missing sections of rubber.
  • Complete loss of the grommet.
  • Brake line contacting the edge of the body opening.
  • Visible rubbing marks on the brake pipe.
  • Worn protective coating on the brake pipe.
  • Rust developing where the pipe has been chafing.
  • Brake line moving excessively in the opening.
  • Squeaking or light rubbing noises where movement is present.
  • Grommet deformation caused by age or incorrect installation.

Because the grommet is small and often located in less visible areas, deterioration may only be discovered during brake-line inspection or restoration work.

Why Replacement Matters:
The brake pipe is a safety-critical component.

A damaged or missing grommet may not immediately cause a braking fault, but continued metal-to-metal contact can gradually damage the pipe.

Replacing the grommet helps restore:

  • Correct brake-line support.
  • Isolation from the vehicle body.
  • Protection against chafing.
  • Reduced vibration.
  • Protection of the pipe’s outer coating.
  • Reduced risk of localised corrosion.
  • Factory-style brake-line routing.
  • Long-term hydraulic system reliability.

About Caliper and Brake Lines

Porsche Calipers & Brake Lines | Design911 Precision Components for Hydraulic Pressure, Control & Performance

Calipers and brake lines are critical elements of your Porsche’s braking system, working together to deliver consistent hydraulic pressure and stopping power. The caliper converts fluid pressure into mechanical force, pressing the brake pads against the disc, while the brake lines ensure precise fluid transfer throughout the system. Maintaining these components in top condition is essential for safety, braking balance, and pedal feel — especially in high-performance or demanding driving environments.

At Design911, we offer a premium range of brake calipers and lines, designed for precision fitment, strength, and reliability. Each component is crafted using corrosion-resistant materials and advanced engineering to deliver consistent hydraulic response, heat resistance, and long-term durability. Whether for road use, restoration, or motorsport applications, our products ensure your Porsche’s braking system performs at its absolute best.

What Do Calipers & Brake Lines Do?

Brake calipers and lines form the hydraulic backbone of the braking system, converting pedal force into controlled, powerful deceleration.

Core Functions:
• Calipers apply clamping force to the brake pads against the discs.
• Brake lines transfer pressurised fluid from the master cylinder to the calipers.
• Ensure consistent pressure and braking balance across all wheels.
• Support heat dissipation and smooth hydraulic operation.
• Maintain precise pedal feel for confident braking control.

Together, these components ensure your Porsche’s brakes deliver the precision, power, and stability required for road and track use alike.

Why Do Calipers & Brake Lines Fail or Degrade?

Both components are exposed to extreme heat, pressure, and environmental elements — conditions that can lead to wear, corrosion, and eventual failure.

Common Causes of Failure Include:
• Corrosion or rust on calipers and fittings.
• Leaking hydraulic seals or damaged pistons.
• Cracked or bulging rubber brake hoses.
• Air or moisture contamination in the hydraulic system.
• Brake fluid degradation causing internal corrosion.
• Physical damage from debris, impact, or improper installation.

When calipers or brake lines fail, braking performance becomes inconsistent or unsafe — with symptoms like spongy pedals, fluid leaks, or uneven braking response.

Why Replace or Upgrade Your Porsche Calipers & Brake Lines?

Replacing worn or corroded components ensures your braking system operates safely and efficiently. Upgrading to high-performance or stainless-steel brake lines enhances pressure consistency and pedal feel, while refurbished or precision-engineered calipers restore perfect hydraulic control.
