Installation:
Type 1:
- Lubricate parking brake lever fulcrum with
suitable brake lube, then attach lever to secondary
brake shoe. Ensure that the lever operates smoothly.
- Lightly lubricate backing plate shoe contact
surfaces with suitable brake lube.
- Connect parking brake lever to cable and
slide secondary brake shoe into position.
- Connect wheel cylinder link to brake shoe
(if equipped).
- Slide parking brake lever strut behind axle
flange and into parking brake lever slot, then
place parking brake anti-rattle spring over
strut.
- Position primary brake shoe on backing plate
and connect wheel cylinder link (if equipped)
and parking brake strut.
- Install anchor plate and position adjuster
cable eye over anchor pin.
- Install primary shoe return spring using
brake spring pliers or equivalent.
- Place protruding hole rim of cable guide
in secondary shoe web hole, then holding guide
in position, install secondary shoe return spring
through cable guide and secondary shoe. Install
spring on anchor pin using brake spring pliers
or equivalent.
NOTE: Ensure cable guide remains
flat against secondary shoe web during and after
return spring installation. Also ensure secondary
spring end overlaps primary spring end on anchor
pin.
- Using suitable pliers, squeeze spring ends
around anchor pin until parallel.
- Install adjuster screw assembly between primary
and secondary brake shoes with star wheel on
secondary shoe side.
NOTE: The left side adjuster
assembly stud is stamped "L" and the
right side is stamped "R". Be sure you
don't mix them up or your brakes will not self-adjust.
- Install shoe-to-shoe spring, then position
adjusting lever spring over pivot pin on shoe
web.
- Install adjusting lever under spring and
over pivot pin, then slide lever slightly rearward.
- Install nails, springs and retainers.
- Thread adjuster cable over guide and hook
end of overload spring in lever. Ensure eye
of cable is pulled tight against anchor and
in a straight line with guide.
- Install brake drum, tire and wheel assembly.
- Adjust brakes.
- If any hydraulic connections have been opened,
bleed brake system.
- Check master cylinder fluid level, and replenish
as necessary.
- Check brake pedal for proper feel and return.
- Lower vehicle and road test. Do not severely
apply brakes immediately after installation
of new brake linings or permanent damage may
occur to linings, and/or brake drums may become
scored. Brakes must be used moderately during
first few hundred miles of operation to ensure
proper burnishing of linings.
Type 2:
- Lightly lubricate support plate shoe contact
surfaces with suitable brake lube.
- Position leading shoe return spring on shoe,
then while holding shoe away from support, engage
return spring in support plate and swing shoe
end into position under anchor.
- Install parking brake lever on trailing shoe.
- Install trailing shoe return spring on shoe,
then while holding shoe away from support, engage
return spring in support plate and swing shoe
end into position under anchor.
- Spread shoes apart and install adjuster screw
assembly. Ensure forked end enters the leading
shoe with curved tines facing down.
- Using a suitable pair of pliers, install
hold-down springs and shoe to anchor springs.
- Pull back parking brake cable return spring
slightly to expose cable, then slide parking
brake cable into parking brake lever and release
spring.
- Install brake drum and bearings. Refer to
individual car chapter for wheel bearing adjustment
procedure.
- Adjust brakes.
- Install tire and wheel assembly.
- If any hydraulic connections have been opened,
bleed brake system.
- Check master cylinder level, replenish as
necessary.
- Check brake pedal for proper feel and return.
- Lower vehicle and road test. Do not severely
apply brakes immediately after installation
of new brake linings or permanent damage may
occur to linings and/or brake drums may become
scored. Brakes must be used moderately during
first several hundred miles of operation to
ensure proper burnishing of linings.
Type 3:
- Lightly lubricate anchor plate shoe contact
surfaces with suitable brake lube.
- Assemble automatic adjuster screw assembly,
return spring and shoe-to-shoe spring to brake
shoe assembly.
- Position lining assembly near anchor plate,
then assemble parking brake lever to trailing
shoe webbing. Secure with C-clip.
- Install lining assembly onto anchor plate.
When positioned, back off adjuster nut to seat
brake shoe ends in wheel cylinder.
- Install hold-down springs.
- Position adjuster lever, then using suitable
pliers, install adjuster lever spring.
- Install brake drum and bearings.
- Adjust brakes.
- Install tire and wheel assembly.
- If any hydraulic connections have been opened,
bleed brake system.
- Check master cylinder level, and replenish
as necessary.
- Check brake pedal for proper feel and return.
- Lower vehicle and road test. Do not severely
apply brakes immediately after installation
of new brake linings or permanent damage may
occur to linings and/or brake drums may become
scored. Brakes must be used moderately during
first several hundred miles of operation to
ensure proper burnishing.
Brake Adjustment:
- Remove rubber adjusting hole covers from
brake supports.
NOTE: Some adjustment holes
are in the backing plate and some are in the drum.
Some are pre-cut and others need to be opened.
You will see a partially stamped cutout in either
the drum or backing plate. To open the hole, use
a hammer and chisel to pop out the cutout. When
you are done, be sure to install rubber covers
to keep water and dirt from entering.
- Release parking brake and back off cable
adjustment to slacken cable.
- Step on the brake five or six times to seat
the shoes.
- Insert a narrow screwdriver into adjusting
nut hole. Move screwdriver handle downward on
left side or upward on right side until wheels
are locked.
- Back off nut 10 clicks.
- Adjust parking brake
- This job will require a moderate skill level.
If you do not feel comfortable doing this job
yourself, then I would recommend taking it to
a qualified mechanic and have it done. It is
not difficult to do, but getting springs and
shoes into position can be tricky. Sometimes
you'll wish you had three hands while you do
this. Be patient and take your time and it will
come together.
Start to finish, to do both sides, you can figure
on about three hours to do the job. If you take
the drums to the parts store to be resurfaced
before you start, they will probably be ready
by the time you are done.
