Information
Brake master cylinder.
OE Match quality replacement for the original Porsche unit referenced by part number 997.355.910.00 / 99735591000. The brake master cylinder converts the force applied to the brake pedal into hydraulic pressure that activates your brake calipers and slows the car. It ensures consistent braking force and modulation under daily driving or spirited use. Without a fully functioning master cylinder, braking performance can be compromised.
Fits:
Porsche 987.1 Boxster 2005 - 2008
Porsche 987.2 Boxster 2009 - 2012
Porsche 987C.1 Cayman 2006 - 2008
Porsche 987C.2 Cayman 2009 - 2012
Porsche 997.1 Carrera 2 2005 - 2008
Diagram ref no 5
Function: It houses pistons and seals that pressurize brake fluid and distribute appropriate pressure to front and rear brake circuits. When you press the brake pedal, this unit ensures the correct volume and pressure of fluid is sent through the lines for dependable stopping power.
Replacing a worn or failing master cylinder is critical for safe braking performance. Over time, internal seals deteriorate, leading to spongy pedal feel, reduced brake responsiveness, or loss of hydraulic pressure. Installing a high-quality OE Match unit restores proper brake pressure, improves pedal feel, and ensures consistent stopping power - essential for both everyday driving and performance scenarios.
When to replace
You should inspect and consider replacing your brake master cylinder if you notice any of the following:
• Brake pedal feels soft, spongy, or sinking
• Visible brake fluid leaks around the firewall or master cylinder
• Inconsistent brake pressure during stopping
• Warning lights on the dashboard indicating brake system issues
• Age-related wear or part has exceeded recommended service life

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.
