UNIT REPAIR

CALIPER OVERHAUL

Disassembly Procedure

1.  Remove the caliper. Refer to”Caliper”in this section.
2.  To prevent damage to the piston when removing it,

place a clean shop towel between the piston and
the caliper.

CAUTION : When applying air pressure at the caliper
inlet port, do not place fingers in front of the piston.
The piston will pop out of its bore with enough force
to cause serious injury.

3.  Apply unlubricated compressed air to the caliper

inlet port, and progressively increase the air pres-
sure until the piston is forced out of the bore.

4.  Remove and discard the outer dust seal.
5.  Remove the inner seal and discard it. Do not

scratch the piston bore or the seal groove when
removing the inner seal.

6.  Remove the bleeder valve and the dust cover.

Assembly Procedure

CAUTION : Keep alcohol and brake fluid away from
the eyes, as serious injury may result.

CAUTION : Keep rubber seals and brake parts away
from oil. Oil can cause the seals to swell and deterio-
rate, and the braking system could become inopera-
tive.

Important : Do not use a hone or any other procedure to
remove material from the piston or caliper bore.

1.  Clean all parts with denatured alcohol or brake

fluid. Dry the parts with unlubricated compressed
air, and blow out all passages in the caliper and the
bleeder valve.

2.  Inspect the piston and the caliper for scoring and

corrosion. Replace any components that show
these conditions.

3.  Insert the bleeder valve and the dust cover.

Tighten

Tighten the bleeder valve to 11 N

S

m (97 lb–in).

4.  Lubricate a new piston inner seal with brake fluid.
5.  Install the piston inner seal into the groove in the

cal–iper bore.

6.  Install the inner seal into the groove in the caliper

bore.

7.  Lubricate the piston with brake fluid.
8.  Install the piston into the caliper.
9.  Install the outer seal into the piston groove. Apply

steady hand pressure until the piston is seated in
the bore.

10.  Inspect the brake shoe linings for minimum thick-

ness. Refer to”Lining Inspection”in this section. If
necessary, install new shoes.

11.  Inspect the guide pins and boots. If the boots are

damaged, or if the guide pins do not slide easily,
replace these parts. Lubricate the guide pins with a
lithium soap base glycol grease or other grease
which will not deteriorate or swell the rubber boots.

12.  Install the caliper. Refer to”Caliper”in this section.
