Information
Brake master cylinder
OE Match replacement brake hydraulic unit designed for direct fitment into the factory braking system without any modification. It converts mechanical force from the brake pedal into hydraulic pressure that actuates the brake calipers and wheel cylinders.
Fits:
Porsche 924 GT 1980 - 1985
Porsche 924S 1986 - 1988 RHD Cars
Porsche 944 1982 - 1985 Cars with ATE brand cylinder
Porsche 944 / 944 Turbo 1985 - 1986 RHD Cars
Diagram ref no 1
The master cylinder generates hydraulic pressure whenever the brake pedal is applied, initiating fluid movement through the brake lines to engage the front and rear brakes. By maintaining proper pressure and fluid control, it supports predictable stopping power and consistent brake pedal feel.
A worn or failing master cylinder can lead to poor brake feel, loss of pedal pressure, or uneven braking performance - all of which compromise safety. Replacing it with an OE Match unit restores reliable brake response and helps preserve the integrity of your Porsche’s braking system.
When to replace:
• Brake pedal feels spongy or soft
• Fluid leakage around the master cylinder
• Internal seal failure reducing hydraulic pressure
• Brake performance feels inconsistent or degraded
• Master cylinder age exceeds typical service life

Manufactured from high-quality cast metal with precision-machined internal bores, corrosion-resistant pistons and high-performance rubber seals, the wheel cylinder is engineered to withstand high hydraulic pressures, repeated braking cycles and prolonged exposure to brake fluid. Designed for direct OE-style installation, it restores dependable braking performance and helps maintain the original operation of the front braking system.
What This Product Does:
- Converts hydraulic brake pressure into mechanical braking force.
- Pushes the brake shoes evenly against the brake drum.
- Delivers smooth and consistent front braking performance.
- Maintains correct hydraulic pressure within the drum brake system.
- Provides balanced braking across the front axle.
- Features a precision 19.05mm bore for OE performance.
- Restores factory braking efficiency and pedal feel.
- Forms an essential part of the hydraulic front drum brake system.
Symptoms Of Wear Or Failure:
- Brake fluid leaks from the wheel cylinder.
- Soft or spongy brake pedal.
- Reduced front braking performance.
- Vehicle pulling to one side during braking.
- Brake shoes contaminated with brake fluid.
- Sticking or seized brake pistons.
- Uneven brake shoe wear.
- Reduced braking efficiency.
- Brake warning light caused by low brake fluid.
- MOT or vehicle inspection failure due to leaking hydraulic components.
Why Replacement Matters:
- The wheel brake cylinder operates under high hydraulic pressure every time the brakes are applied and is continually exposed to brake fluid, moisture and temperature changes. Over time, the internal seals can deteriorate, while corrosion or wear within the cylinder bore may cause leaks or prevent the pistons from moving freely.
- A failing wheel cylinder can significantly reduce braking performance, contaminate the brake shoes with fluid and create an inconsistent brake pedal feel. Continued operation with a leaking or seized cylinder can increase stopping distances, accelerate brake component wear and compromise vehicle safety.
- Replacing a worn or damaged front wheel brake cylinder restores reliable hydraulic operation and balanced braking performance. The OE Match replacement features a precision 19.05mm bore, factory-style fitment and premium-quality materials, ensuring dependable braking, improved safety and long-lasting durability for your Porsche.
