Without Antilock Brakes
The base brakes on a vehicle not equipped with Antilock Brake System (ABS) use a standard compensating port master cylinder, while vehicles equipped with ABS use a center valve design master cylinder. The information provided here applies only to the non-ABS master cylinder. For information on the master cylinder used on vehicles with ABS, refer to the Antilock Brake System.Fig 4 Type 3 Master Cylinder. Less ABS:
The non-ABS master cylinder is a four-outlet design with two screw-in proportioning valves attached directly to the inboard side of the master cylinder housing. Vehicles equipped with rear drum brakes use a master cylinder with a 21 mm bore diameter, while vehicles equipped with rear disc brake use a 22.2 mm bore master cylinder.
The master cylinder body is an anodized aluminum casting. It has a machined bore to accept the master cylinder piston and also has threaded ports with seats for hydraulic brake line connections. The brake fluid reservoir mounted to the top of the master cylinder assembly is made of a see-through plastic.
