The connecting line carries brake fluid from the brake master cylinder into the relevant rear brake hydraulic circuit. A secure, correctly routed brake line is essential for brake pressure transfer, pedal feel, and safe braking performance.
Functions
• Replaces the rear brake master cylinder connecting line
• Suitable for left-hand drive cars
• For vehicles without brake servo
• Carries brake fluid through the hydraulic brake system
• Supports correct brake pressure and pedal feel
• Helps prevent brake fluid leaks from aged or corroded lines
• OE Match replacement for Porsche 911, 912, and 914 brake system repair.
Why Replace This Part?
Brake hydraulic lines can corrode, kink, crack, fatigue, block, or leak due to age, moisture, road dirt, brake fluid contamination, and previous brake work. A faulty connecting line can cause brake fluid loss, soft pedal feel, reduced braking performance, or failed inspection. Replacing the line helps restore safe hydraulic brake operation.
When to Replace This Part
• Brake fluid is leaking from the master cylinder line area
• The original brake line is corroded, kinked, blocked, or damaged
• Brake pedal feel is soft, inconsistent, or poor
• Brake master cylinder service is being carried out
• Brake pipes or hydraulic fittings are being renewed
• The vehicle has failed inspection due to brake pipe condition
• The car is undergoing Porsche 911, 912, or 914 brake system restoration.
Where it fits on the car
This connecting line fits at the brake master cylinder hydraulic line area on left-hand drive Porsche 911, 912, and 914 models without brake servo. It forms part of the rear brake hydraulic circuit.

This is a high performance upgrade to the stock Porsche 911 Master Cylinder for non-power brake applications. The increased 23mm bore (vs. 19mm) should be used on cars that are fitted with 'larger than stock' brakes to increase pedal pressure and feel. Unlike other kits on the market, which require modifications to the lines and the push rod, our Master Cylinder is a direct fit.
The master cylinder is designed to deliver precise brake pedal feel, consistent hydraulic pressure, and reliable braking performance. As the central component of the hydraulic braking system, it plays a critical role in ensuring safe, responsive, and predictable stopping power.
What This Product Does:
- Converts brake pedal input into hydraulic pressure
- Supplies brake fluid pressure to the braking system
- Provides increased fluid displacement through its larger bore design
- Supports performance and upgraded brake system applications
- Maintains consistent brake pedal feel and braking response
- Works with dual-circuit braking systems for enhanced safety
Symptoms Of Wear Or Failure:
- Soft or spongy brake pedal feel
- Brake pedal slowly sinking under pressure
- Reduced braking effectiveness
- Brake fluid leaks around the master cylinder
- Inconsistent brake pressure or pedal response
- Difficulty building hydraulic pressure
- Brake warning lights illuminating
- Internal seal wear causing pressure loss between circuits
Why Replacement Matters:
- Restores correct hydraulic pressure throughout the braking system
- Improves brake pedal feel and responsiveness
- Ensures consistent and predictable braking performance
- Prevents brake fluid leaks and pressure loss
- Supports safe operation of dual-circuit braking systems
- Maintains compatibility with performance brake upgrades
- Reduces the risk of braking system failure
- Helps preserve driver confidence and vehicle safety under all driving conditions
