Master Cylinder

MASTER CYLINDER
DESCRIPTION
This vehicle uses 2 differently designed master cylinder assemblies depending on whether the vehicle is or is not equipped with antilock brakes.
Vehicles not equipped with ABS use a standard compensating port master cylinder design, while vehicles equipped with ABS use a center valve design master cylinder.
On vehicles equipped with ABS brakes, the master cylinder is a two outlet design. On vehicles not equipped with ABS brakes, the master cylinder is a 4 outlet design. All vehicles are equipped with a master cylinder having a bore diameter of 22.2 mm.






The master cylinder assembly consists of the following components. The body of the master cylinder is an anodized aluminum casting. It has a machined bore to accept the master cylinder piston and threaded ports with seats for hydraulic brake line connections. The brake fluid reservoir of the master cylinder assembly is made of a see through plastic.

OPERATION
secondary pistons apply brake pressure through the chassis brake tubes and proportioning valves to each brake assembly.






On Non-ABS master cylinders, the primary outlet ports supply hydraulic pressure to the right front and left rear brakes. The secondary outlet ports supply hydraulic pressure to the left front and right rear brakes.







On ABS master cylinders, the primary outlet port supplies hydraulic pressure to the right front and left rear brakes. The secondary outlet port supplies hydraulic pressure to the left front and right rear brakes.
