4D-2 FRONT BRAKES
DESCRIPTION AND OPERATION
GENERAL DESCRIPTION
When the brakes are applied, fluid pressure is sent to
each brake caliper. The pressure at the caliper is ex-
erted equally against the caliper piston. The pressure
applied to the piston is transmitted directly to the
inboard brake pad. This forces the pad against the inner
surface of the brake rotor. At the same time, fluid
pressure within the caliper piston bore forces the caliper
to slide inward on its guide pins. This action brings the
outboard pad into contact with the outer surface of the
brake rotor. This pressure on both sides of the brake
rotor causes friction, bringing the vehicle to a stop.
BRAKE CALIPER
The caliper has a single bore and is mounted to the
steering knuckle with two mounting bolts. Hydraulic
pressure, created by applying the brake pedal, is con-
verted by the caliper to a stopping force. This force
acts equally against the piston and the bottom of the
caliper bore to move the piston outward and to slide
the caliper inward, resulting in a clamping action on
the rotor. This clamping action forces the linings against
the rotor, creating friction to stop the vehicle.Important:
•Replace all components included in the repair kits
used to service the caliper.
Lubricate the rubber parts with clean brake fluid to
ease assembly.
Do not use lubricated shop air on brake parts, as
damage to the rubber components may result.
If any hydraulic component is removed or discon-
nected, it may be necessary to bleed all or part of
the brake system. Refer to Section 4F, Antilock
Brake System And Traction Control System.
Replace the pads in axle sets only.
The torque values specified are for dry, unlubricated
fasteners.
Perform the service operations on a clean bench,
free from all oily material.
BRAKE PADS
There are two brake pads mounted to each caliper, one
inboard and one outboard. As front disc brake pad wear,
master cylinder reservoir brake fluid level will drop. Fluid
level should be checked after replacing pads.
BRAKE ROTOR
Each front disc brake rotor is vented to help cool it dur-
ing and after brake applications.
