The OE MATCH Brake Master Cylinder, Standard 19mm Bore is a hydraulic braking system component designed to convert brake pedal force into hydraulic pressure, allowing effective operation of the vehicle’s braking system. Featuring a standard 19mm bore, this master cylinder replicates the original factory specification, providing the correct hydraulic balance, pedal feel, and braking performance intended by Porsche.
For Cars With Stop Light Switch.
NOTE: Does Not Come With New Switch. Has To Be Transferred Over Or Bought Separately. Part Number 90161311500
Fits:
The master cylinder is engineered for precise brake modulation, reliable fluid pressure generation, and long-term durability. As the central component of the braking system, it distributes hydraulic pressure to the brake calipers or wheel cylinders, ensuring safe and predictable vehicle stopping performance.
What This Product Does:
- Converts brake pedal force into hydraulic pressure
- Distributes brake fluid pressure throughout the braking system
- Provides the correct hydraulic volume for standard braking setups
- Maintains original factory brake pedal feel and response
- Supports safe and consistent braking performance
- Works with dual-circuit braking systems for added safety
Symptoms Of Wear Or Failure:
- Soft or spongy brake pedal feel
- Brake pedal slowly sinking under sustained pressure
- Reduced braking performance or longer stopping distances
- Brake fluid leakage around the master cylinder
- Inconsistent brake pressure or uneven braking response
- Difficulty maintaining hydraulic pressure
- Brake warning lights illuminating
- Internal seal deterioration causing fluid bypass and pressure loss
Why Replacement Matters:
- Restores proper hydraulic brake pressure
- Improves brake pedal feel and responsiveness
- Maintains factory braking characteristics and performance
- Prevents brake fluid leaks and pressure loss
- Supports safe operation of the dual-circuit braking system
- Reduces the risk of brake system failure
- Ensures predictable and consistent stopping performance
- Helps maintain driver confidence and vehicle safety under all driving conditions
