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.

DIAGNOSTIC INFORMATION AND PROCEDURES
KAA4D020
PAD INSPECTION
1. Raise and suitably support the vehicle.
2. Remove the front wheel. Refer to Section 2E, Tires
and Wheels.
3. Visually check the linings for minimum thickness
and wear.
4. Measure the thickness.
Important: The minimum discard thickness of the
lining is 2 mm (0.08 inch).
5. Install the pads in axle sets only.
6. Install the rear wheels. Refer to Section 2E, Tires
and Wheels.
7. Lower the vehicle.
FRONT DISC BRAKE ROTOR
INSPECTION
Thickness variation can be checked by measuring the
thickness of the rotor at four or more points around the
circumference of the rotor. All measurements must be
made at the same distance in from the edge of the
rotor.
A rotor that varied by more than 0.013 mm (0.0005
inch) can cause pedal pulsations and/or front end
vibration during brake applications. A rotor that does
not meet these specifications should be refinished to
specifications or replaced.
During manufacturing, the brake rotor and the toler-
ances of the braking surface regarding flatness, thick-
ness variation, and lateral runout are held very close.
The maintenance of close tolerances on the shape of
the braking surfaces is necessary to prevent brake
roughness.In addition to these tolerances, the surface finish must
be held to a specified range. The control of the braking
surface finish is necessary to avoid pulls and erratic
performance and to extend lining life.
Light scoring of the rotor surfaces not exceeding 0.4
mm (0.016 inch) in depth, which may result from normal
use, is not detrimental to brake operation.
Using a commercially available dial indicator, check
lateral runout as follows:
Notice: Permissible lateral runout is a maximum 0.07
mm (0.003 inch). If lateral runout exceeds the specifica-
tion, ensure that there is no dirt between the rotor and
the hub and that contact surfaces are smooth and free
from burrs.
1. Position the transaxle in NEUTRAL.
2. Remove the rotor. Refer to “Rotor” in this section.
3. Fasten the brake rotor to the wheel hub with two
wheel nuts. Refer to Section 2E, Tires and Wheels.
KAA4D030
4. Fasten a dial indicator to the brake caliper.
5. Set the gauge probe tip to approximately 10 mm
(0.394 inch) from the outer edge of the brake rotor,
perpendicular to the disc and under slight preload.
6. Remove the dial indicator and the wheel nuts that
connect the rotor to the hub.
Important: Since accurate control of the tolerances
is necessary for proper performance of the disc
brakes, refinishing of the rotor should be done only
with precision equipment.
7. Refinish the rotor, if required, with precision equip-
ment. Discard the rotor if it fails to meet the above
specifications after refinishing.
8. Install the rotor. Refer to “Rotor” in this section.
