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

- Units suited to road and motorsport preparation
Understanding OEMatch Brake Master Cylinder
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original brake master cylinder. OE (Original Equipment) refers to parts matching original specifications for the brake master cylinder and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM brake master cylinder engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The brake master cylinder converts pedal pressure into hydraulic force that operates the brake calipers. It maintains even brake force distribution, supports ABS and traction control systems where fitted, and sustains a firm, predictable pedal feel when functioning correctly.
Benefits Include
- Restores safe and consistent braking performance and pedal feel
- Prevents fluid leaks and loss of hydraulic pressure
- Maintains correct brake balance across all wheels
- Constructed to resist corrosion and withstand thermal cycling
Why Brake Master Cylinder Wear and Fail
- Worn internal seals leading to pressure loss or external leaks
- Corrosion from moisture-contaminated brake fluid
- Scored or pitted cylinder bores that reduce seal integrity
- Air ingress or age-related degradation of rubber components
The Importance of Replacing with OEMatch Brake Master Cylinder
Timely replacement restores full hydraulic pressure and consistent braking response, helping to preserve control and safety for Porsche models. A serviceable master cylinder reduces the risk of spongy pedals, fluid loss and uneven brake performance while supporting systems such as ABS that depend on stable hydraulic input.
Advantages
- Manufactured to original-spec dimensions and tolerances for fit and function
- Suitable for both classic restoration and modern Porsche applications
- Supported by OEMatch’s catalogueuing and cross-references for easier part identification
