Wheel brake cylinder 19.05mm. Porsche 356A /365B (35642126 / 35642125)  ❭  69535151

Front Wheel Brake Cylinder 19.05mm.
The OE Match Front Wheel Brake Cylinder 19.05mm is a premium-quality replacement hydraulic brake cylinder designed for compatible Porsche models equipped with drum brake front axles. Manufactured to OE specifications for fit, bore size and durability, this 19.05mm wheel cylinder converts hydraulic brake pressure into mechanical force, pushing the brake shoes against the drum to deliver safe, smooth and reliable braking performance.

Fits:

• Porsche 356 1950-55
• Porsche 356A 1955-59
• Porsche 356B 1959-63

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.
