4. Install a C-clamp onto the front brake caliper and
tighten until the caliper pistons bottom in the
caliper housing. Verify that the C-clamp is centrally
positioned on both the caliper housing and the
brake pad. This provides an even clamping force
on both pistons and should prevent the pistons
from becoming wedged in their bores due to
uneven clamping force.
5. Remove front brake caliper. Refer to Brake
Caliper Replacement (Front).
6. Remove the inner and outer brake pads from the
caliper mounting plate.
Use a screwdriver if necessary to remove the
pads from their installed position.
7. Inspect the caliper guide pins for free movement
in the caliper mounting plate.
8. Inspect the caliper guide pin boots for proper
seating in the retaining groove of the caliper
guide pin and the rear caliper mounting plate. (

boots if any of the following conditions exist:

Installation Procedure
Important: Use GM replacement brake pads for all
GM vehicles in order to maintain the balance in
performance between the front and rear brakes. GM
replacement brake parts are carefully selected in order
to guarantee minimum stopping distance and
maximum controllability over the full range of operating
conditions. Installing front or rear brake pads not
recommended by GM may change the intended
performance, wear characteristics, and brake balance
of the vehicle.
1. Install the inner and outer pads into the caliper
mounting plate. Ensure that the wear sensor is
at the trailing edge of the outer brake pad
when the wheel is rotating forward. If the wear
sensor is not at the trailing edge, the outer brake
pad is on the wrong side.
2. Install the front brake caliper. Refer to Brake
Caliper Replacement (Front).
