1986 TOYOTA CAMRY V20 brakes

PRECAUTIONS
1. Care must be taken to replace each part properly as it
could affect the performance of the brake system and re-
sult in a driving hazard. Replace the parts with parts of the
same part number or equivalent.
2. It is very important to keep parts and the area clean when
repairing the brake system.

noise when brakes are
applied
Note: Brake friction
materials inherently
generate noise and heat in
order to dissipate eniergy.
As a result, occasional
squeal is normal and is
aggravated by severe
environmental conditions
such as cold,' heat,
wetness, snow, salt, mud,
etc. This occasional squeal
is not a functional problem
and does not indicate any
loss of brake effectivenessInspect, repair or replace

REPLACEMENT OF BRAKE PADS
HINT: If a squealing noise occurs from the front brakes
while driving, check the pad wear indicator. If there are
traces of the indicator contacting the rotor disc, the brake
pad should be replaced.

8. CHECK OPERATION OF AUTOMATIC ADJUSTING
MECHANISM
(a) Move the parking brake lever of the rear shoe back
and forth, as shown. Check that the adjuster turns.
If the adjuster does not turn, check for incorrect installation
of the rear brakes.
(b) Adjust the adjuster length to the shortest possible
amount. 7. INSTALL FRONT SHOE
(a) Install the anchor spring between the front and rear
shoes.
(b) Set the front shoe in place with the end of the shoe
inserted in the wheel cylinder and the adjuster in
place.
(c) Using SST, install the shoe hold±down spring, cups
and pin.

NOTICE: Do not allow oil or grease to get on the ru
bing face.
(c) Align the adjusting hole on the brake drum and largest
hole on the axle carrier, install the brake drum. (d) Using SST, connect the return spring.

REPLACEMENT OF BRAKE PADS
HINT: If a squealing noise occurs from the brakes while
driving, check the pad wear indicator. If there are traces
of the indicator contacting the rotor disc, the brake pad
should be replaced.
1. REMOVE REAR WHEEL
Remove the wheel and temporarily fasten the rotor disc
with the hub nuts.
