Ranger 2WD V6-182 3.0L (1995)
Brake Caliper: Description and Operation
OPERATION
All vehicles are equipped with front disc brake calipers (2B120). Front disc brake calipers use pin rail-type caliper assemblies with a cast iron
rotor integral with the front hub assembly.
The front disc brake caliper (2B120) consists of a pin slider caliper housing, inner and outer shoe and lining assemblies, and a wheel cylinder
piston (2196). The front disc brake caliper slides on two pins which also attach the front disc brake caliper to the front wheel spindle (3105).
The caliper housing contains a wheel cylinder piston. The wheel cylinder piston has a molded rubber dust boot on its outer end that is pressed into
a cylinder bore groove to prevent cylinder contamination. There is also a rectangular section rubber piston seal located in the cylinder bore
providing sealing between the cylinder and wheel cylinder piston. This seal also causes the wheel cylinder piston to retract once the brakes are
released.
