4. Stretch the dust boot rearward to straighten the boot folds, then move the boot forward until the
fold snaps into place.
5. Install the piston into the caliper bore and press the piston down to the bottom of the caliper bore by
hand or with the handle of a hammer.
CAUTION:
When assembling, the force applied to the piston to seat it in the bore must be applied uniformly
to avoid cocking and binding of the piston.
6. Seat the dust boot in caliper.
7. Install the new caliper bleed screw.
8. Install the caliper (See Front Brake Caliper Removal & Installation in Section 12 Brakes).

Description
This Antilock Brake System (ABS) uses components of the base brake system, but also features the following com-
ponents:
•Hydraulic Control Unit and Antilock Brake System Module (ABS module)
• Wheel Speed Sensors (wheel speed sensor) - Four sensors (one sensor at each wheel making it a four-chan-
nel system)
The purpose of the ABS is to prevent wheel lockup under braking conditions on virtually any type of road surface.
Antilock braking is desirable because a vehicle that is stopped without locking the wheels retains directional stability
and some steering capability. This allows the driver to retain greater control of the vehicle during braking.LTSM120040

ABS Braking
•ABS operation is available at all vehicle speeds above 20 km/h. If a wheel locking tendency is detected during
a brake application, the brake system enters the ABS mode. During ABS braking, hydraulic pressure in the four
wheel circuits is modulated to prevent any wheel from locking. Each wheel circuit is designed with a set of
electric solenoids to allow modulation. The system can build and release pressure at each wheel, depending on
signals generated by the wheel speed sensors at each wheel and received at the ABS Module.
• There are a few performance characteristics of the ABS that may at first seem abnormal, but in fact are nor-
mal. These characteristics are described below.
If the electrical system malfunctions, the Fail-Safe function is activated, the ABS becomes inoperative and
the ABS warning lamp turns on.
During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is normal.
Stopping distance may be longer than that of vehicles without ABS when vehicle drives on rough, gravel, or snow-covered (fresh, deep snow) roads.
