1986 TOYOTA CAMRY V20 brake pads

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.

2. INSPECT PAD LINING THICKNESS
Check the pad thickness through the cylinder inspection
hole and replace pads if not within specification.
Minimum thickness: 1.0 mm (0.039 in.)
4. REMOVE FOLLOWING PARTS:
(a) Two anti±squeal springs.
(b) Two brake pads
(c) Two or four anti±squeal shims
(d) Two pad wear indicator plates
(e) Four pad support plates 1. REMOVE FRONT WHEEL
Remove the wheel and temporarily fasten the rotor disc
with the hub nuts.
(b) Remove the brake cylinder and suspend it so the hose
is not stretched.
HINT: Do not disconnect the brake hose. 3. REMOVE CYLINDER FROM TORQUE PLATE
(a) Remove two installation bolts from the torque plate.
± BRAKE SYSTEMFront BrakeBR±19

8. INSTALL NEW PADS
(a) Install new pad wear indicator plate to inner pad.
NINT: Be sure the arrow on the pad wear indicator
plate is pointing i n the direction of the disc rotation.
(b) (Except 2VZ±FE Engine of w/ A.B.S.)
Install the one anti±squeal shim to the each pad.
(c) (For 2VZ±FE Engine of w/ A.B.S.)
Install the two anti±squeal shims to the each pad.
HINT: Apply disc brake grease to both side of the inner
anti±squeal shim of the outside pad.
(d) Install the pads onto each support plate.
NOTICE: Do not allow oil or grease to get on the
rubbing face.
(e) Install the two anti±squeal springs.
9. INSTALL CYLINDER
(a) Draw out a small amount of brake fluid from the reser-
voir.
(b) Press in piston with a hammer handle or an equiva-
lent.
HINT: Always change the pad on one wheel at a time as
there is a possibility of the opposite piston flying out.
(c) Insert the brake cylinder carefully ±so the boot is not
wedged. 5. CHECK ROTOR DISC THICKNESS
(See step 2 on page BR±23)
6. CHECK ROTOR DISC RUNOUT
(See step 3 on page BR±23)
7. INSTALL PAD SUPPORT PLATES

REMOVAL OF CYLINDER
(See page BR±18)
1. DISCONNECT BRAKE LINE
Remove the union bolt and disconnect the brake line. Use
a container to catch the brake fluid.(d) Install and torque two installation bolts.
Torque: 400 kg±cm (29 ft±Ib, 39 N¿m)
10. INSTALL FRONT WHEEL
11. CHECK THAT FLUID LEVEL IS MAX LINE
2. REMOVE CYLINDER FROM TORQUE PLATE
