wheel torque TOYOTA CAMRY V20 1986 Service Information

7. When necessary, use a sealer on gaskets to prevent
leaks.
8. Carefully observe all specifications for bolt tighten-
ing torques. Always use a torque wrench.
9. Use of special service tools (SST) and special ser-
vice materials (SSM) may be required, depending on
the nature of the repair. Be sure to use SST and SSM
where specified and follow the proper work proce-
dure. A list of SST and SSM can be found at the back
of this manual.
10. When replacing fuses, be sure the new fuse has the
correct amperage rating. DO NOT exceed the fuse
amp rating or use one of a lower rating.
11. Care must be taken when jacking up and supporting
the vehicle. Be sure to lift and support the vehicle at
the proper locations.
(a) If the vehicle is to be jacked up only at the front or
rear end, be sure to block the wheels in order to
ensure safety.
(b) After the vehicle is jacked up, be sure to support it
on stands. It is extremely dangerous to do any
work on the vehicle raised on jack alone, even for a
small job that can be finished quickly.

AT5032
(A540H)
The A540H automatic transaxle design is based on the A540E automatic transaxle and equipped with a
center differential and transfer.
This transaxle has the same hydraulic multiplate clutch in the center differential limiting control mecha-
nism as the A241H automatic transaxle on the Corolla All-Trac/4WD Station Wagon. The fluid pressure
acting on the hydraulic multiplate clutch of the A540H is controlled by the ECT ECU (Electronic Control
Unit) according to the vehicle driving conditions. As a result, torque is distributed to the front and rear
wheels appropriately at all times to maximize the overall performance of the 4WD vehicle.
NOTICE: Special handling methods are necessary for full-time 4WD vehicles during inspection and
maintenance. Instructions concerning these handling methods are given on Camry Repair Manual
(Pub. No. RM199U) on page IN-8.

CHECK AND ADJUSTMENT OF PARKING
BRAKE
1. CHECK THAT PARKING BRAKE LEVER TRAVEL IS
CORRECT
Pull the parking brake lever all the way up, and count the num-
ber of clicks.
Parking brake levertravel at 20 kg (44.1 Ib, 196 N):
5 ± 8 clicks
If incorrect, adjust the parking brake.
2. IF NECESSARY, ADJUST PARKING BRAKE LEVER
TRAVEL
HINT: Before adjusting the parking brake, make sure that the
rear brake shoe clearance has been adjusted.
For shoe clearance adjustment, see steps 8 and 9 on page
BR±32 or step 8 on page 48.
(a) Remove the console box.
(b) Loosen the lock nut and turn the adjusting nut until the
lever travel is correct.
(e) Tighten the lock nut.
Torque: 55 kg±cm (48 in.±Ib, 5.4 N±m)
(d) Install the console box. 3. BEGIN BLEEDING AIR FROM BRAKE OR WHEEL
CYLINDER WITH LONGEST HYDRAULIC LINE
(a) Connect the vinyl tube to the brake or wheel cylinder
bleeder plug, and insert the other end of tube in a
halffull container of brake fluid.
(b) Slowly pump the brake pedal several times.
(c) While having an assistant press on the pedal, loosen
the bleeder plug until fluid starts to runout. Then close
the bleeder plug.
(d) Repeat (b) and (c) until there are no more air bubbles
in the fluid.
(e) Tighten the bleeder plug.
Bleeder plug tightening torque:
85 kg±cm (74 in.±!b, 8.3 N±m)
4. REPEAT PROCEDURE FOR EACH WHEEL(c) Block off the outer holes with your fingers, and re-
lease the brake pedal.
(d) Repeat (b) and (c) three or four times.

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.
