Master Cylinder

DESCRIPTION
The master cylinder is mounted on the power brake booster. It has outlet brake tubes leading from its primary and secondary ports that lead to the combination valve.






The dual piston master cylinder has a semi-clear polypropylene reservoir and an anodized aluminum body. The fill cap diaphragms are slit to allow atmospheric pressure to equalize on both sides of the diaphragm.
The master cylinder body and pistons are not serviceable or replaceable components of the master cylinder. The only replaceable component of the master cylinder is the fluid reservoir.

OPERATION
The master cylinder is the component of the vehicle's brake system that develops the hydraulic pressure required to apply the brakes and stop the vehicle. The master cylinder has two pistons with rubber lip seals located in the bore of the master cylinder that are used to pressurize the brake fluid in the brakes hydraulic system. The brake fluid is pressurized by the force applied to the brake pedal by the driver's foot.
The master cylinder's primary and secondary pistons feed the front and rear brakes. The primary port of the master cylinder feeds the front brakes through the combination valve. The secondary port of the master cylinder feeds the rear brakes through the combination valve.
