The Porsche Wheel Brake Cylinder 69535151200 is a replacement hydraulic brake cylinder used in the front right upper position of the drum-brake system on selected classic Porsche 356 models.
Fits:
- Porsche 356A 1955-59
- Porsche 356B 1959-63
Diagram Ref No 8
Featuring an approximately 19.05 mm bore, the wheel cylinder converts hydraulic brake-fluid pressure into mechanical movement, pushing the brake shoes outward against the inside of the brake drum when the brake pedal is applied.
As a critical hydraulic braking component, correct cylinder condition is essential for consistent braking force, balanced front braking and dependable pedal response.
What This Product Does:
When the driver presses the brake pedal, the master cylinder generates hydraulic pressure in the brake-fluid circuit.
This pressure reaches the wheel brake cylinder, where internal pistons move outward and apply force to the brake shoes.
The wheel brake cylinder helps:
- Convert hydraulic brake pressure into mechanical braking force
- Push the front brake shoes against the brake drum
- Generate braking force at the front wheel
- Maintain consistent hydraulic operation
- Support balanced braking across the front axle
- Maintain predictable brake-pedal response
- Allow the brake shoes to release correctly when pedal pressure is removed
It is an essential part of the original drum-brake system.
Symptoms Of Wear Or Failure:
Common symptoms of a failing wheel brake cylinder include:
- Brake-fluid leakage around the brake drum
- Wetness behind the brake backing plate
- Brake fluid on the brake shoes
- Soft or spongy brake pedal
- Brake pedal requiring additional travel
- Reduced braking performance
- Vehicle pulling to one side under braking
- Uneven front braking
- One wheel braking more strongly than the other
- Wheel cylinder pistons sticking or seizing
- Brake shoes failing to apply correctly
- Brake shoes failing to release fully
- Uneven brake-shoe wear
- Low brake-fluid level
- Repeated need to top up brake fluid
- Corrosion or pitting inside the cylinder bore
Any unexplained loss of brake fluid should be investigated immediately.
Why Replacement Matters:
The wheel brake cylinder is a safety-critical component.
A leaking or seized cylinder can reduce braking force at the affected wheel and upset the braking balance across the front axle.
Continued operation with a failing cylinder can contribute to:
- Increased stopping distance
- Unpredictable vehicle behaviour under braking
- Loss of brake fluid
- Air entering the hydraulic system
- Brake-shoe contamination
- Accelerated brake-component wear
- Reduced pedal firmness
- Partial loss of braking performance
Replacing a worn cylinder restores proper hydraulic sealing and piston movement.
