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

Diagram Ref No 8  

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.

Banjo bolt for brake line. For dual circuit master cylinder.
This banjo bolt is used to connect a brake line (via a banjo fitting) to the dual-circuit master cylinder on classic Porsche models. It fastens the brake line banjo fitting to the master cylinder and provides the internal fluid passage needed for brake hydraulic flow. A sound banjo-bolt connection supports firm pedal feel and dependable braking performance.
Sold each, 2 pieces needed per car

Fits:
Porsche 356 B/C 1.6L 01/1959 - 12/1965
Porsche 914 1.7L-2.0L 01/1969 - 02/1976

Diagram ref no 41

Installed at the master cylinder brake outlet, the banjo bolt clamps the banjo fitting in place and allows brake fluid to pass through its drilled channels under pressure. Because it sits in a high-pressure circuit, correct fit and condition are essential for leak-free operation.

Old banjo bolts can corrode, round off, or suffer sealing-surface wear, which increases the risk of brake fluid leaks and loss of hydraulic pressure. Replacing with a fresh bolt helps restore a secure connection and supports safe, reliable braking.

When to replace:
•  Brake fluid seepage around the banjo fitting/master cylinder
•  Corrosion, damaged threads, or rounded bolt head
•  During master cylinder replacement or brake line refurbishment
•  When rebuilding a classic brake system using new lines/fittings

Wheel Brake Cylinder, Front Right Upper.

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.
