FIG. 72—Brake Wheel Cylinder—Typical

DISASSEMBLY

1.
Remove the links and the rubber

boots from the ends of the brake cyl-

inder. Remove the pistons, cups, and

return spring from the cylinder bore

(Fig. 12).

2.
Remove the bleeder screw from

the cylinder.

INSPECTION

1.
Wash all parts in clean brake

fluid. Dry with compressed air.

2.
Replace scored pistons. Always

replace the rubber cups and dust

boots.
3.
Inspect the cylinder bore for

score marks or rust. If either condi-

tion is present the cylinder bore must

be honed. However, the cylinder

should not be honed more than 0.003

inch beyond its original diameter.

4.
Check the bleeder hole to be sure

that it is open.

ASSEMBLY

1.
Apply a light coating of heavy-

duty brake fluip! to all internal parts.

2.
Thread the bleeder screw into the

cylinder and tighten securely.

3.
Insert the return spring, cups,

and pistons into their respective posi-

tions in the cylinder bore (Fig. 12).
Place a boot over each end of the cyl-

inder. Bleed the brake system.

HYDRAULIC LINE REPAIR

Steel tubing is used throughout the

brake system with the exception of the

flexible hoses at the front wheels and

at the fear axle housing brake tube

connection (Figs. 17 thru 21).

Always bleed the applicable pri-

mary or secondary brake system after

primary or secondary brake system

hose or line replacement. Centralize

the pressure differential valve after

bleeding the system.

BRAKE TUBE

REPLACEMENT

If a section of the brake tubing be-

comes damaged, the entire section

should be replaced with tubing of the

same type, size, shape and length.

Copper tubing should not be used in a

hydraulic system. When bending

brake tubing to fit underbody or rear

axle contours, be careful not to kink

or crack the tube.

All brake tubing should be double

flared properly to provide good leak-

proof connections. Clean the brake

tubing by flushing with clean brake

fluid before installation.

When connecting a tube to a hose,

tube connector, or brake cylinder,

tighten the tube fitting nut to specified

torque with Milbar tool 1112-144 or

equivalent.

BRAKE HOSE

REPLACEMENT

A flexible brake hose should be re-

placed if it shows signs of softening,

cracking, or other damage.

When installing a new front brake

hose,
position the hose to avoid con-

tact with other chassis parts. Place a

new copper gasket over the hose fit-

ting and thread the hose assembly into

the front wheel cylinder. Engage the

opposite end of the hose to the brack-

et on the frame. Install the horsesho-

e-type retaining clip, and connect the

tube to the hose with the tube fitting

nut (Figs. 17 thru 21).

A rear brake hose should be in-

stalled so that it does not touch the

muffler outlet pipe or shock absorber.

Thread the hose into the rear brake

tube connector. Engage the front end

of the hose to the bracket on the

frame. Install the horseshoe-type re-

taining clip, and connect the tube to

the hose with the tube fitting nut.procarmanuals.com

cylinder. Do not pull the metal tube

away from the cylinder. Pulling the

tube out of the cylinder connection

will bend the metal tube and make in-

stallation difficult. The tube will sepa-

rate from the cylinder when the cylin-

der is removed from the backing

plate.

4.
On all except the front wheels on

Ford, Mercury, and Meteor models,

remove the wheel cylinder attaching

bolts and lock washers and remove the

cylinder. On the front wheel of Ford,

Mercury and Meteor models, remove

the nut and washer that attaches the

cylinder to the anchor pin. Remove

the cylinder from the anchor pin.

INSTALLATION

Wipe the end(s) of the hydraulic

line to remove any foreign matter be-

fore making connections.

On all models except Ford, Mer-

cury and Meteor, to install a front

wheel cylinder, position the cylinder to

the backing plate. Install the two lock

washers and attaching bolts. Torque

them to specifications.

On Ford, Mercury and Meteor

models, to install a front wheel cylin-

der, position the cylinder on the an-

chor pin against the backing plate. In-

stall the washer and cylinder attaching

nut on the anchor pin, and torque it

to specification. Lock the washer re-

tainer securely.

2.
Install a new copper gasket over

the hose fitting. Thread the hose into

the cylinder and tighten it to specified

torque.

3.
Engage the opposite end of the

hose to the bracket on the frame. In-

stall the horseshoe-type retaining clip,

and connect the brake tube to the

hose with the tube fitting nut. Tighten

the nut to specification with tool

1112-144.

4.
To install a rear wheel cylinder,

place the rear wheel cylinder into po-

sition. Enter the tubing into the cylin-

der, and start the tube fitting nut into

the threads of the cylinder.

5.
Secure the cylinder to the back-

ing plate by installing the attaching

bolts and lock washers.

6. Tighten the tube fitting nut to

specification with tool 1112-144.

7.
Install the links in the ends of

the wheel cylinder, install the shoes

and adjuster assemblies, and adjust

the shoes as outlined in this section.

1.
Remove the front wheel cover.

Remove the wheel and tire assembly

from the hub and rotor assembly. Be

careful to avoid damage or interfer-

ence with the caliper splash shield or

bleeder screw fitting.

2.
Disconnect the brake line from

the caliper. Cap the hose to prevent

*he brake fluid from leaking from the

master cylinder.

3.
Remove the safety wire and the

two bolts that attach the caliper as-

sembly to the spindle.

4.
Lift the caliper assembly off the

rotor and place it on the bench.

Installation

1.
Position the caliper assembly on

the rotor, and mate the mounting bolt

holes in the caliper with those in the

spindle. It may be necessary to push

the caliper piston into the cylinder

bore to obtain clearance between the

shoe and lining assembly and the

rotor.

2.
Install the caliper to spindle at-

taching bolts and torque them to spe-

cification. The upper bolt must be

tightened first. Install the safety wire

on the bolts and twist the wire ends at

least five turns. Push the wire ends

against the spindle to avoid interfer-

ence with the brake hose and the

steering stop. Check to insure that the

rotor runs squarely and centrally be-

tween the two brake shoes.

3.
Position the brake hose fitting

with a new copper washer on each

side of the fitting on the caliper as-

sembly. Install the bolts and torque to

specification.

and
torque them
to
spec-

ification. Check
to
insure that
the

rotor runs squarely
