Set Of 7.

• Porsche 356 /A 1.1-1.6 01/1950-12/1961 for LHD cars

Manufactured to provide OE-style fitment and functionality, this kit is designed to replace ageing, corroded, damaged or leaking rigid brake lines, helping restore the integrity of the vehicle's hydraulic braking system.

The kit contains seven brake pipes intended for applicable left-hand-drive Porsche 356 vehicles. The pipes are supplied ready for forming and must be carefully bent to match the original routing and installation requirements.

The Porsche 356 braking system operates hydraulically, using brake fluid pressure generated by the master cylinder to activate the wheel brake cylinders.

The rigid brake lines play a critical role in this process by transporting pressurised brake fluid between the master cylinder and the appropriate braking components.

Over time, original metal brake pipes can deteriorate due to corrosion, exposure to moisture and road salt, vibration, repeated heating and cooling, or mechanical damage.

Corroded or weakened brake lines may eventually develop leaks, resulting in hydraulic pressure loss, reduced braking efficiency or complete brake failure.

The OE MATCH Brake Line Kit provides a practical replacement solution for restoring the original single-circuit brake pipe arrangement.

It is particularly suitable for complete brake system refurbishment, chassis restoration and replacement of heavily corroded original pipework.

Ideal for classic Porsche maintenance and restoration projects, this seven-piece kit helps preserve the vehicle's original braking configuration while supporting dependable hydraulic operation.

What This Product Does:
The brake line kit replaces the rigid hydraulic pipes responsible for carrying pressurised brake fluid throughout the vehicle's braking system.

When the driver presses the brake pedal, the master cylinder generates hydraulic pressure.

This pressure travels through the brake pipes and associated flexible hoses to the wheel brake cylinders, allowing the braking system to apply force to the brake shoes and slow the vehicle.

The brake pipes must maintain a secure, leak-free hydraulic connection for the brakes to operate correctly.

Their key functions include:

• Hydraulic Brake Fluid Transfer: Carry pressurised brake fluid from the master cylinder towards the wheel braking components.
• Brake Pressure Transmission: Allow hydraulic pressure generated by the brake pedal to reach the appropriate brake circuits and wheel cylinders.
• Leak-Free Brake Operation: Provide sealed hydraulic connections when correctly formed, fitted and tightened.
• Reliable Braking Response: Support consistent transfer of brake pressure during normal braking.
• Single-Circuit System Compatibility: Maintain the original brake pipe arrangement of applicable Porsche 356 single-circuit systems.
• Front and Rear Brake Connections: Form part of the hydraulic pipework serving the vehicle's braking assemblies.
• Structural Pipe Routing: Provide rigid hydraulic connections along the intended chassis and body mounting routes.
• Brake System Restoration: Replace corroded or damaged original metal brake pipes.
• Hydraulic Integrity: Help prevent brake fluid loss caused by defective rigid pipework.
• Original-Style Braking Configuration: Support restoration of the original Porsche 356 hydraulic brake layout.
• Complete Pipework Refurbishment: Allow multiple ageing rigid brake lines to be renewed as part of one repair project.

On classic Porsche 356 models, original brake lines may have been in service for many decades.

Common signs of deterioration include:

1. Visible Brake Pipe Corrosion

Rust forming on the metal brake lines is one of the most common indications of deterioration.

Advanced corrosion can weaken the pipe walls and eventually lead to hydraulic leaks.

2. Brake Fluid Leakage

Wet patches, fluid droplets or visible seepage around brake pipes and fittings may indicate a damaged line or leaking connection.

Brake fluid leaks should be investigated immediately.

3. Soft or Spongy Brake Pedal

A soft or spongy brake pedal may indicate air within the hydraulic system.

Air can enter following fluid loss or inadequate bleeding, although the symptom can have several other causes.

4. Brake Pedal Sinking Under Pressure

A pedal that gradually sinks while steady pressure is applied can indicate hydraulic pressure loss.

Potential causes include leaking brake pipes, wheel cylinders, hose connections or an internal master cylinder fault.

5. Reduced Braking Performance

A hydraulic leak or pressure-loss problem can reduce braking effectiveness and increase stopping distances.

6. Low Brake Fluid Level

An unexplained reduction in reservoir fluid level may indicate leakage somewhere in the braking system.

The complete system should be inspected.

7. Corroded Brake Pipe Unions

Rust or corrosion around pipe fittings may damage the connections and make removal difficult.

Severely corroded unions may also contribute to leakage.

8. Cracked or Damaged Brake Pipes

Physical damage, incorrect bending, vibration fatigue or previous poor repairs may weaken the rigid pipework.

9. Flattened or Kinked Pipe Sections

Improper bending or accidental impact can distort brake pipes and affect their structural condition.

Damaged sections should be replaced rather than straightened repeatedly.

10. Brake Fluid Around Chassis Components

Fluid collecting around the underbody, wheel arches or brake line connections can indicate leakage.

11. Previous Improper Repairs

Incorrectly flared pipes, unsuitable fittings, unsupported sections or poorly routed lines may compromise braking safety.

12. Excessive Brake Pipe Movement

Missing or damaged retaining clips may allow rigid brake pipes to vibrate or rub against surrounding components.

13. Corrosion Hidden Beneath Clips

Moisture trapped around retaining clips and mounting points can create localised corrosion that may be difficult to identify without close inspection.

14. Brake Warning Symptoms

Where fitted, a brake system warning indication may alert the driver to a problem.

However, early Porsche 356 models do not provide the comprehensive electronic fault monitoring found on modern vehicles.

15. Age-Related Deterioration

Even where no external leak is visible, extensive corrosion or poor pipe condition identified during restoration may justify replacement.

Why Replacement Matters:

• Replacing deteriorated or damaged brake pipes is essential for maintaining the safety, reliability and hydraulic integrity of your classic Porsche 356 braking system.
• The brake lines form the hydraulic network that transfers pressure from the master cylinder to the individual braking components.
• Unlike cosmetic trim or comfort-related components, brake pipes are directly involved in the vehicle's ability to stop safely.
