Removal
CAUTION:
IUse suitable tool for assembly and disassembly of brake
lines and hoses.
IBe careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately. DO
NOT RUB IT OFF.
IAll hoses must be free from excessive bending, twisting
and pulling.
1. Connect a vinyl tube to air bleeder valve.
2. Drain brake fluid from each air bleeder valve by depressing
brake pedal.
3. Remove flare nut securing brake tube to hose, then withdraw
lock spring.
4. Cover openings to prevent entrance of dirt whenever discon-
necting hydraulic line.
Inspection
Check brake lines (tubes and hoses) for cracks, deterioration or
other damage. Replace any damaged parts.
Installation
CAUTION:
IRefill with new brake fluid ªDOT 4º.
INever reuse drained brake fluid.
1. Tighten all flare nuts and connecting bolts.
Flare nut:
:9-11N×m (0.9 - 1.1 kg-m, 78 - 95 in-lb)
Connecting bolt:
:17-20N×m (1.7 - 2.0 kg-m, 12 - 14 ft-lb)
2. Refill until new brake fluid comes out of each air bleeder valve.
3. Bleed air. Refer to ªBleeding Brake Systemº, BR-8.

Inspection
Check brake pedal for following items:
IBrake pedal bend
IClevis pin deformation
ICrack of any welded portion
ICrack or deformation of clevis pin stopper
Adjustment
Check brake pedal free height from dash reinforcement panel.
H: Free height
Refer to SDS, BR-85.
D: Full stroke
Refer to SDS, BR-85.
C: Clearance between pedal stopper and threaded end
of stop lamp switch
0.3 - 1.0 mm (0.012 - 0.039 in)
A: Pedal free play
1.0 - 3.0 mm (0.039 - 0.118 in)
If necessary, adjust brake pedal free height.
1. Loosen lock nut and adjust pedal free height by turning brake
booster input rod. Then tighten lock nut.
Make sure that tip of input rod stays inside of clevis as shown.
2. Loosen lock nut and adjust clearance ªCº with stop lamp switch.
Then tighten lock nuts.
3. Check pedal free play.
Make sure that stop lamps go off when pedal is released.
4. Check brake system for leaks, accumulation of air or any dam-
age to components (master cylinder, etc.); then make neces-
sary repairs.

Removal and Installation
IDrain oil from vacuum pump before removal.
Manually rotate fan belt clockwise to discharge any oil which
may have accumulated in vacuum pump.
IInstall vane so that its round surface faces pump housing.
IAfter installing vacuum pump assembly, apply 5 m(0.2 Imp fl
oz) of engine oil into vacuum pump assembly. Then, make sure
that pulley can be smoothly rotated by hand.
Inspection
Clean all parts and check them as follows:
ICheck for wear or scratches on mating surfaces of rotor and
vacuum pump housing and on rotor and center plate. If wear
or scratches are noted, replace those parts.
ICheck for wear or scratches on vanes. If necessary, replace.

3. Swing cylinder body upward. Then remove pad and anti-noise
shims.
CAUTION:
IWhen cylinder body is swung up, do not depress brake
pedal because piston will pop out.
IEnsure that brake fluid does not come into contact with
dustcover and rotor.
IBe careful not to twist brake hoses.
Brake pad thickness (new):
10 mm (0.39 in)
Wear limit (min. thickness):
2 mm (0.08 in)
IAfter installing new brake pads, check brake fluid level at
brake fluid reservoir.
Removal
IRemove torque member fixing bolts and union bolt.
Disassembly
Push out piston with dust cover with compressed air.
Use a wooden block so that the 2 pistons come out evenly.
CAUTION:
IWear protecting clothes and safety goggles.
IDo not hold your fingers in front of the pistons.
IBe careful not to scratch piston and/or cylinder faces.
Inspection
INSPECTION OF BRAKE DRAG FORCE
ªResidual pairº describes the friction pressure of the disc brake
shoes against the disc when the brake pedal is not applied.
1. Swing cylinder body upward.
2. Make sure that wheel bearing is adjusted properly. Refer to
section FA.
3. Measure rotating force (F
1).

Purpose
The Anti-lock Brake System (ABS) with an integrated Electronic Brake force Distribution (EBD) system con-
sists of electronic and hydraulic components. It allows you to control the braking force so that wheel lock can
be avoided during braking.
The advantages of ABS with EBD
1) Better tracking performance through improved steering wheel control.
2) Improved maneuverability and safer vehicle control.
3) Improved vehicle stability by preventing flat spins.
4) Shorter stopping distance and optimal utilisation of the rear brakes under many different circumstances.
Operation
IABS with EBD has self-test capabilities. The ABS warning lamp is illuminated for 1 second each time the
ignition switch is turned ªONº. After the engine is started, the ABS warning lamp turns off. An ABS self-test
is performed the first time the vehicle reaches 6 km/h (4 MPH) to ensure the system is operational. A
mechanical noise may be heard as the ABS performs this self-test and is a normal part of the self-test
feature. If a malfunction is detected during this check, the ABS warning lamp will stay on.
During the self-test, it also performs a EBD check when it detects a failure the ABS warning light will go
on simultaneously with the brake warning light and an audible sound will sound constantly.
IEBD system will only operate when the ABS is not in active status and it uses the inlet valves of ABS con-
trol unit to limit the pressure to the rear wheels when they tend to go into slip.
IWhen the vehicle speed is less than 10 km/h (6 MPH) the ABS system does not operate.
IWhile driving, a mechanical noise may be heard during ABS operation, this is a normal system condition.

ANTI-LOCK BRAKE SYSTEM
BR-37

System Description
Sensor
The sensor unit consists of a gear-shaped sensor rotor and a sen-
sor element. The element contains a bar magnet around which a
coil is wound. The sensor is installed on the back of the brake rotor
and the rear brake drum.
As the wheel rotates, the sensor generates a sine-wave pattern.
The frequency and voltage increase(s) as the rotating speed
increases.
Control unit
The control unit computes the wheel rotating speed by the signal
current sent from the sensor. Then it supplies a DC current to the
actuator solenoid valve. It also controls ON-OFF operation of the
valve relay and rotor relay. If any electrical malfunction should be
detected in the ABS or EBD system, the control unit causes the
warning lamp(s) to light up, combined with an audible sound.
In this condition, the ABS or EBD will be deactivated by the control
unit, and the vehicle's brake system reverts to normal operation.
