Fig. 2G-35 Inboard Brakeshoe Installation
(17) Install outboard shoe. Shoe ears should rest on
upper surface of caliper mounting ears and lower shoe
tab should fit into cutout in caliper. Be sure shoe is fully
seated.
(18) Position caliper over rotor and in support shield
and bracket. Align mounting holes in caliper and
bracket.
(19) Install caliper mounting bolts. Be sure bolts
pass under inboard shoe retaining ears and insert bolts
until they enter bores in outboard shoe and caliper
mounting ears. Thread bolts into support bracket and
tighten to 35 foot-pounds (47 N*m) torque.
(20) Fill master cylinder with brake fluid and pump
brake pedal to seat shoes.
(21) Clinch upper ears of outboard shoe until radial
clearance between shoe and caliper is eliminated.
N O T E : Outboard shoes with formed ears are designed
for original installation only and are fitted to the cali-
per. These shoes should never be relined or recondi-
tioned for future installation.
(22) Install wheel and tire.
(23) Lower vehicle.
(24) Check master cylinder fluid level. Add fluid as
required to within 1/4 inch (6.35 mm) of reservoir rim.
(25) Apply brakes several times to seat brakeshoes.
(26) Check and correct master cylinder fluid level as
necessary.
(27) Test brake operation before moving vehicle.

Removal
(1) Remove two-thirds of brake fluid from master
cylinder front reservoir.
(2) Raise vehicle.
(3) Remove wheel and tire.
(4) Bottom caliper piston using screwdriver or large
C-clamp.
(5) Clean brake line hose connection thoroughly us-
ing shop cloth.
(6) Disconnect brake line at caliper. Remove brake
line bolt and copper gaskets. Discard copper gaskets.
(7) Cap or tape open end of brake hose to prevent
dirt entry.
(8) Remove caliper and remove brakeshoes from
caliper.
N O T E : Work on one caliper at a time only. If shoes are
to be reused, mark their location for assembly reference.
Disassembly
(1) Clean caliper exterior with brake cleaning
solvent.
(2) Drain remaining fluid from caliper and place
caliper on clean work surface.
(3) Pad caliper interior with clean shop cloths (fig.
2G-36).
(4) Insert air nozzle into caliper fluid inlet hole and
slowly apply just enough air pressure to ease piston out
of bore (fig. 2G-36).
WARNING: Do not, under any circumstances, place
fingers in front of the piston in an attempt to catch or
protect it. In addition, use only enough air pressure to
ease the piston out of the bore. Excessive air pressure
can eject the piston with enough force to cause damage
or injury.
