16: Install the guide pins and wipe off any excess
lubricant.
17: Press the smaller heat insulator plate onto the
outer brake pad.
18: Assemble the other heat insulator plates, silencer
plate and brake pads as shown in the illustration
and place into the caliper casting.
Note: The inner pad has the wear indicator tab.
19: Install the spreader springs and brake pad guide
pins.
20: Install the lock spring into the guide pins.
21: Push each spreader spring down over the lock
spring and insert the tabs into the holes in the
brake pads.
22: Resurface the rotor to remove all grooves
or runout. Refer to the front axle section for
information on removing the hub.
23: Measure the thickness of the rotor. If the
thickness of the rotor is less than the service limit
then the rotor must be replaced. Refer to the front
axle section for information on removing/installing
the brake rotor.
24: Using new caliper bolt locking plates, install the
caliper assembly onto the front axle. Refer to the
front axle section for information on installing the
caliper.
Rebuild Caliper
This procedure assumes that the component has been
removed from the vehicle. Refer to the component
assembly removal instructions for details and warnings
regarding the removal and installation procedure.
1: Remove the brake pads from the caliper. Refer to
“Replace Pads” procedure.
2: Take the rubber boot off of the caliper body.
3: Place a 9/16 inch (14.3 mm) thick block of wood
between the brake piston and the caliper body.
4: Hold the block of wood against the piston.
5: Using compressed air,
slowly
increase pressure
in the caliper until the piston is pushed out.
6: Remove the wood block and piston.
7: Remove the o-ring.
8: Inspect the caliper bore for any signs of damage
or wear. If there are any signs of damage or wear
then the caliper should be replaced.
9: Inspect the piston for any signs of damage or
wear. If there are any signs of damage or wear
then the piston should be replaced.
10: Lubricate a new o-ring with DOT 3 brake fluid and
install it into the caliper bore.
11: Lubricate the piston with DOT 3 brake fluid and
CAREFULLY place the piston into the bore and
press in using hand pressure only. Excessive or
uneven force may damage the piston sides and
result in a brake fluid leak.
12: Install a new boot over the piston and caliper
body.
13: Reassemble the brake pads. Refer to “Replace
Pads” procedure.
Do not use more than 25 PSI(1.72 Bars) to remove
the piston. If the piston does not come out using 25
PSI then the piston is seized and the caliper should
be replaced.
