What does a brake master cylinder do?
It converts the force you put on the brake pedal into hydraulic pressure and sends brake fluid through the lines to the calipers or wheel cylinders to apply the brakes.
What are the rubber components made of?
Dorman makes all of the rubber components from a high-quality EPDM compound, which resists glycol-based brake fluid.
What are signs a master cylinder may need replacing?
Common signs include a soft or sinking brake pedal, fluid leaking at the cylinder, and a brake warning light. Other faults can cause these too, so diagnose the cause first.
Is anything special required during installation?
Follow the vehicle's service information. Replacing a master cylinder normally requires bleeding the brake system with the fluid type the vehicle specifies to remove air.
