Product Information
Brake master cylinder
The ATE brake master cylinder is a high-quality hydraulic braking component for selected Porsche 924 Turbo and 928 models. Corresponding with Porsche part number 92835501104, it is designed to replace a worn, leaking or internally failing original master cylinder and restore dependable hydraulic brake operation.

Fits:
Porsche 924 Turbo 1981 - 1982
Porsche 928/S 4.5L, 4.7L 1978 - 1983

The master cylinder converts movement from the brake pedal and servo into hydraulic pressure. This pressure is distributed through the brake lines to the calipers, allowing the vehicle to slow down in a controlled and predictable manner. As the central pressure-generating component in the braking system, its condition is critical to pedal feel and braking safety.

Manufactured by ATE, a recognised specialist in original-equipment braking technology, this replacement unit is designed to provide accurate pressure control, reliable sealing and consistent operation. ATE master cylinders are engineered for good bleeding characteristics and resistance to wear and contamination within the hydraulic system.

What This Part Does
When the brake pedal is pressed, pistons inside the master cylinder force brake fluid through separate hydraulic circuits. The resulting pressure operates the brake calipers at each wheel.

The tandem design uses two hydraulic circuits, helping retain partial braking capability if one circuit develops a fault. A serviceable master cylinder is essential for maintaining:
Consistent brake-pedal pressure
 Predictable braking response
 Correct hydraulic pressure distribution
 Reliable operation of the front and rear brakes
 Secure containment of brake fluid
