(7) When the solenoids are OFF, check that the brake
pedal can be depressed.
If the pedal cannot be depressed, replace the hydraulic brake
booster.
(h) Jack up and support the vehicle.
(i) Release the parking brake lever.
(j) Shift the transfer shift lever to ºNº position and check that
the rear wheels by rotating them by hand.
(k) Inspect the rear TRAC & VSC solenoid operation.
(1) Select the ºSA3º and ºSTRº on the TOYOTA hand-
held tester.
(2) Turn the ºSA3º and ºSTRº ON simultaneously with
the TOYOTA hand-held tester, and check that the
rear wheel does not rotate by hand.
HINT:
When rotating the wheel fast, the fail-safe function is activated
and judgement cannot be made properly. So rotate the wheel
as slowly as possible.
If the rear wheels rotate, replace the hydraulic brake booster.
(3) Turn the ºSA3º and ºSTRº OFF simultaneously, and
check that the rear wheels by rotating them by
hand.
HINT:

To protect the solenoids, TOYOTA hand-held tester turns
OFF automatically 2 sec. after every solenoid has been
turned ON.

When rotating the wheel fast, the fail-safe function is acti-
vated and judgement cannot be made properly. So rotate
the wheel as slowly as possible.
NOTICE:
When operating it continuously, set the interval of more
than 20 sec.
If the rear wheels stop, replace the hydraulic brake booster.
(l) Inspect the right rear ABS solenoid.
(1) Select the ºSA3º, ºSTRº and ºSRRHº, on the TOYO-
TA hand-held tester.
(2) Turn the ºSA3º, ºSTRº and ºSRRHº ON simulta-
neously with the TOYOTA hand-held tester, and
check that the right rear wheel by rotating it by hand.
HINT:

To protect the solenoids, TOYOTA hand-held tester turns
OFF automatically 2 sec. after every solenoid has been
turned ON.

When rotating the wheel fast, the fail-safe function is acti-
vated and judgement cannot be made properly. So rotate
the wheel as slowly as possible.

When solenoid is OFF, the wheel might stop temporarily.
However if the wheel rotates again, the function works
normally.
If the rear wheels stop, replace the hydraulic brake booster.

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.
