NOTE:
All front fasteners are important attaching parts in that they could affect the performance of vital parts
and systems, and/or could result in major repair expense. They must be replaced with one of same
part number or with an equivalent part if replacement becomes necessary. Do not use a replacement
part of lesser quality or substitute design. Torque values must be used as specified during reassem-
bly to assure proper retention of all parts. There is to be no welding as it may result in extensive dam-
age and weakening of the metal.

Malfunctioning ABS (Antilock brake system), if
equippedCheck system and replace as nec-
essary.

unison)Pad linings and/or shoe linings are wet with
water or stained with oil in some brakesReplace.
Drum-to-shoe clearance out of adjustment in
some brakes
(Malfunctioning auto adjusting mechanism)Check for inoperative auto adjust-
ing mechanism.
Disc and/or drum is out of round in some
brakesReplace.
Wheel tires are inflated unequally Inflate equally.
Malfunction in wheel cylinders Repair or replace.
Disturbed front end alignment Adjust as prescribed.
Unmatched tires on same axle Tires with approximately the same
amount of tread should be used on
the same axle.
Restricted brake pipes or hoses Check for soft hoses and damaged
lines. Replace with new hoses and
new double-walled steel brake tub-
ing.
Malfunctioning caliper assembly Check for stuck or sluggish pistons
and proper lubrication of caliper
slide bush.
Caliper should slide.
Loose suspension parts Check all suspension mountings.
Loose calipers Check and torque bolts to specifica-
tions.
Noise (high pitched
squeak without brake
applied)Front lining worn out Replace linings.
Contact wear indicator to brake disc Replace pads.

maturelyMaladjusted sensor spring length of LSPV, if
equippedCheck or adjust.
Malfunction LSPV assembly, if equipped Replace assembly.

5) If rear brake pressure is not within specification, adjust it by
changing bolt (2) position as follows.
If rear brake pressure is higher than specification, move bolt
(2) center side and if it is lower, out side.
Repeat steps 3) and 4) until rear brake pressure is within
specification.
After adjustment, be sure to torque nut (1) to specification.
Tightening torque
LSPV nut (a) : 25 N·m (2.5 kg-m, 18.0 lb-ft)
6) Upon completion of fluid pressure test, bleed brake system
and perform brake test.
MASTER CYLINDER AND BRAKE FLUID
LEVEL INSPECTION
1) Check master cylinder and reservoir tank for crack, damage
and brake fluid leakage. If any faulty condition exists, correct
or replace.
2) Check that brake fluid level is between MAX and MIN marks
on reservoir tank.
2
1, (a)
NOTE:
Be sure to use particular brake fluid either as indicated
on reservoir cap of that vehicle or recommended in
owner’s manual which comes along with that vehicle.
Use of any other fluid is strictly prohibited.
Fluid level should be between MIN and MAX lines marked
on reservoir.
When brake warning lamp lights sometimes during driv-
ing, replenish fluid to MAX level.
When fluid decreases quickly, inspect brake system for
leakage. Correct leaky points and then refill to specified
level.
CAUTION:
Do not use shock absorber fluid or any other fluid which
contains mineral oil. Do not use a container which has
been used for mineral oil or a container which is wet from
water. Mineral oil will cause swelling and distortion of
rubber parts in hydraulic brake system and water mixed
into brake fluid will lower fluid boiling point. Keep all fluid
containers capped to prevent contamination.

1) Fill master cylinder reservoir with brake fluid and keep at
least one-half full of fluid during bleeding operation.
2) Remove bleeder plug cap.
Attach a vinyl tube (1) to bleeder plug, and insert the other
end into container (2).
3) Depress brake pedal several times, and then while holding it
depressed, loosen bleeder plug about one-third to one-half
turn.
4) When fluid pressure in cylinder is almost depleted, retighten
bleeder plug.
5) Repeat this operation until there are no more air bubbles in
hydraulic line.
6) When bubbles stop, depress and hold brake pedal and
tighten bleeder plug.
Tightening torque
Front bleeder plug : 11.0 N·m (1.1 kg-m, 8.0 lb-ft)
Rear bleeder plug : 8.0 N·m (0.8 kg-m, 6.0 lb-ft)
7) Then attach bleeder plug cap.
8) After completing bleeding operation, apply fluid pressure to
pipe line and check for leakage.
9) Replenish fluid into reservoir up to specified level.
10) Check brake pedal for sponginess. If found spongy, repeat
entire procedure of bleeding.

4) Remove brake pads (3).
INSPECTION
Check pad lining for wear. When wear exceeds limit, replace with
new one.
Brake pad thickness (lining thickness)
Standard : 10 mm (0.40 in.)
Limit : 1 mm (0.04 in.)
INSTALLATION
1) Set brake pad springs (1) and shim (2) and install brake
pads (3).
2) Install caliper and tighten caliper pin bolts (1) to specified
torque.
Tightening torque
Caliper pin bolts (a) : 26 N·m (2.6 kg-m, 19.0 lb-ft)
3) Tighten wheel temporarily and lower lift.NOTE:
Hang removed caliper (1) with a wire hook (4) or the like
so as to prevent brake hose from bending and twisting
excessively or being pulled.
Don’t operate brake pedal with brake pads removed.
CAUTION:
Never polish pad lining with sandpaper. If lining is pol-
ished with sandpaper, hard particles of sandpaper will be
deposited in lining and may damage disc. When pad lin-
ing requires correction, replace it with a new one.
NOTE:
When pads are removed, visually inspect caliper for
brake fluid leak. Correct leaky point, if any.
NOTE:
For right side brake, install pad with wear indicator (4) to
vehicle center side.
