Master Cylinders Parts For Acura Tl. Carl Bush: A master cylinder is used to convert force from the brake pedal into the hydraulic pressure that operates the brake calipers. If the brake master cylinder is leaking braking fluid or if there are unsecured reservoirs on the cylinder which are holding the fluid, then you will almost be guaranteed of having a low brake fluid level.

The amount of pressure generated is a function of the force being applied, divided by the master cylinder bore area. If your brake fluid becomes tainted, the rubber seals on the master cylinder have broken and the fluid cannot effectively hold pressure. The "master" cylinder distributes this pressure to the brake calipers or wheel cylinders, also known as "slave" cylinders.

If it isn't, buy the proper brake fluid for your vehicle and add it until the level meets the line.

The brake master cylinder supplies hydraulic pressure to your brake calipers and wheel cylinders.
