Brake line kit. Porsche 911 1963-67 LHD  ❭  1661500310

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.

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.
