Brake Master Cylinder: Description and Operation
MASTER CYLINDER
DESCRIPTION
Two different master cylinders are used on this vehicle. Vehicles without Antilock Brakes (ABS) use a standard compensating-port master cylinder,
while vehicles equipped with ABS use a center-valve design master cylinder.
ABS vehicles, equipped with rear disc brakes, use a master cylinder with a 23.82 mm (0.937 inch) bore diameter, while non-ABS vehicles, equipped
with rear disc brakes, use a 22.23 mm (0.875 inch) bore diameter master cylinder.
The ABS master cylinder is a two-outlet design and the brake tubes from these primary and secondary outlet ports lead directly to the Integrated
Control Unit (ICU) before going to each wheel brake (Fig. 94).
The non-ABS master cylinder is a four-outlet design (one for each wheel brake) with two screw-in proportioning valves (one for each rear wheel
brake). One is attached directly to the inboard side of the master cylinder housing while the other is attached to the bottom (Fig. 96).
