2. Place a clamp over the ends
of the brake cylinder as shown in
Fig.

4. Remove the brake shoe assem-
blies, following procedures outlined
in this section.
4. Disconnect the brake line from
the brake cylinder. On a car with
a vacuum brake booster, be sure
the engine is stopped and there is
no vacuum in the booster system
before disconnecting the hydraulic
lines.
To disconnect the hose at a front
cylinder, loosen the tube fitting that
connects the opposite end of the hose
to the brake tube at a bracket on the
frame. Remove the horseshoe-type
retaining clip from the hose and
bracket, disengage the hose from the
bracket, then unscrew the. entire hose
assembly from the front wheel cyl-
inder.
At a rear cylinder, unscrew the
tube fitting that connects the tube
to the cylinder. Do not pull the
metal tube away from the cylin-
der. Pulling the tube out of the
cyIinder connection will bend the
metal tube and make
instaIlation
difficult. The tube will separate from
the cylinder when the cylinder is
removed from the backing plate.
5. Remove the wheel cylinder at-
taching bolts and lock washers and
remove the cylinder.
a. Position the cylinder in place
against the backing plate. In-
stall the two lock washers and
attaching bolts. Torque them
to specifications.
b. Install a new copper gasket
over the hose fitting. Thread
the hose assembly into the
cylinder and tighten it se-
curely.
c. Engage the opposite end of
the hose to the bracket on
the frame, install the
horse-
shoe-type retaining clip, and
connect the brake tube to
the
hose with the tube fitting nut.
Tighten the nut to specifica-
tions.
2. To install a rear cylinder:
a. Position the rear wheel cyl-
inder in place against the
backing plate. Enter the tub-
ing into the cylinder, and
start the tube fitting nut into
the threads of the cylinder.
b. Secure the cylinder to the
backing plate with the at-
taching bolts and lock wash-
, ers.
c. Tighten the tube fitting nut
to specifications.

so that the hole in the axle shaft
flange lines up with the backing plate
retaining nuts and remove the nuts.

1. Position a new rear backing
plate on the retaining bolts in the
gxle housing flange. Insert the axle
shaft into the housing so that the
splines engage the differential side

against the backing plate. Install the
retaining nuts through the access
hole in the axle shaft flange.

to the wheel spindle and install the
retaining bolts and nuts.
