Well, the master cylinder is tasked with supplying hydraulic pressure to the braking system. So when you initially step on the brake pedal the linkage activates a piston within the system and this piston then displaces hydraulic fluid.
PROCEDURES: 1  Remove the top of the master cylinder reservoir. 2  Using a turkey baster, suck out as much of the old brake fluid as you can. 3  Clean any sediment out of the reservoir with a clean, lint-free rag.  Fill the master cylinder with clean brake 1  fluid. Replace the top of the master cylinder reservoir.
