REPLACEMENT
1. REMOVE REAR WHEEL
2. INSPECT PAD LINING THICKNESS
Check the pad thickness through the caliper inspection hole
and replace pads if not within the specification.
Minimum thickness: 1.0 mm (0.039 in.)
3. REMOVE BRAKE CALIPER
(a) Remove the 2 mounting bolts.
(b) Remove the caliper and suspend it so the hose is not
stretched.
HINT:
Do not disconnect the flexible hose.
4. REMOVE 2 PADS AND 4 ANTI-SQUEAL SHIMS
5. REMOVE 4 PAD SUPPORT PLATES
NOTICE:
The pad support plates can be used again provided that
they have sufficient rebound, no deformation, cracks or
wear, and have had all rust, dirt and foreign particles
cleaned off.
6. CHECK DISC THICKNESS AND RUNOUT
(See page BR-30)
7. INSTALL PAD SUPPORT PLATES
8. INSTALL NEW PADS
NOTICE:
When replacing worn pads, the anti-squeal shims must be
replaced together with the pads.
Install the 4 anti-squeal shims to the pads.
HINT:
Apply disc brake grease to both sides of the inner anti-squeal
shims (See page BR-24).
NOTICE:
Do not allow oil or grease to get on the rubbing face.
9. INSTALL CALIPER
(a) Draw out a small amount of brake fluid from the reservoir.
(b) Press in the pistons with a hammer handle or an equiva-
lent.
HINT:

Always change the pads on one wheel at a time as there
is a possibility of the opposite piston flying out.

If the piston is difficult to push in, loosen the bleeder plug
and push in the piston while letting some fluid escape.

5. ECU (ELECTRONIC CONTROL UNIT)
Many ECUs are mounted in this vehicle.
Take the following precautions during body repair to prevent damage to the ECUs.

Before starting electric welding operations, disconnect the negative (-) terminal cable from the battery.
When the negative (-) terminal cable is disconnected from the battery, memory of the clock and audio
systems will be cancelled. So before starting work, make a record of the contents memorized by each
memory system. Then when work is finished, reset the clock and audio systems as before.
When the vehicle has tilt and telescopic steering, power seat and outside rear view mirror, which are all
equipped with memory function, it is not possible to make a record of the memory contents. So when the
operation is finished, it will be necessary to explain this fact to the customer, and request the customer to
adjust the features and reset the memory.

Do not expose the ECUs to ambient temperatures above 80°C (176°F).
NOTICE: If it is possible the ambient temperature may reach 80° (176°F) or more, remove the ECUs
from the vehicle before starting work.

Be careful not to drop the ECUs and not to apply physical shocks to them.
