c. If calculated balance weight value exceeds 50 g (1.76 oz), install
two balance weight sheets in line with each other (as shown in
the figure).
CAUTION:
Do not install one balance weight sheet on top of another.
3. Start wheel balancer again.
4. Install drive-in balance weight on inner side of road wheel in the
wheel balancer indication position (angle).
CAUTION:
Do not install more than two balance weights.
5. Start wheel balancer. Make sure that inner and outer residual
unbalance values are 10 g (0.35 oz) each or below.

If either residual unbalance value exceeds 10 g (0.35 oz), repeat installation procedures.
Wheel balance (Maximum allowable unbalance):
RotationEES000J3

After rotating the tyres, adjust the tyre pressure.

Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tyre, etc.).
CAUTION:
When installing wheels, tighten the wheel nuts diagonally
by dividing the work two to three times in order to prevent
the wheels from developing any distortion.
Maximum allowable
unbalanceDynamic (At rim flange) Less than 10 g (0.35 oz) (one side)
Static (At rim flange) Less than 20 g (0.70 oz)

BRAKE PIPING AND HOSE

3. Using a flare nut wrench, loosen brake tube flare nuts and dis-
connect brake tube from brake hose.
4. Remove union bolts and disconnect caliper assembly from
brake hose.
5. First remove lock spring from brake tube and strut mounting
positions. Then remove brake hose.
INSTALLATION
CAUTION:

Refill with new brake fluid “DOT 3” or “DOT4”.

Never reuse drained brake fluid.
1. Connect brake hose to caliper assembly and tighten union bolt to the specified torque.
CAUTION:

Securely connect brake hose to the protrusion on the cylinder body.

Do not reuse the copper washer for union bolt.
2. Connect brake hose to strut and fix with lock spring.
3. Connect brake hose to brake tube. Temporarily tighten flare nuts by hand as far as they will go. Secure
them with the lock spring.

REMOVAL
CAUTION:

Do not allow brake fluid to spill or splash on painted surfaces. Brake fluid can seriously damage
paint. If it gets on a painted surface, wipe it off immediately and wash it away with water.

Do not bend or twist brake hose sharply, or strongly pull it.

Cover brake fluid line joints to prevent dust and other foreign material.
1. Connect a vinyl tube to bleed valve.
2. Drain brake fluid gradually from bleed valve of each wheel while depressing brake pedal.
3. Using a flare nut wrench, remove brake tube flare nuts and dis-
connect brake tube from brake hose.
4. Remove lock spring.
INSTALLATION
CAUTION:

Refill with new brake fluid “DOT 3” or “DOT 4”.

Never reuse drained brake fluid.
1. Connect brake hose to the brake tube. Temporarily tighten flare nut by hand as far as it will go.
2. Fix brake hose by lock plate.

WARNING:

Clean brake pads with a vacuum dust collector to minimize the hazard of airborne particles or
other materials.
CAUTION:

When cylinder body is open, do not depress brake pedal because piston will pop out.

Be careful not to damage piston boot or spill brake fluid oil on rotor. Always replace shims when
replacing pads.

If shims are rusted or show peeling of the rubber coat, replace them with new shims.

It is not necessary to remove torque member mounting bolt and brake hose union bolt except for
disassembly or replacement of caliper assembly. In this case, suspend cylinder body with wire so
as not to stretch brake hose.

Burnish the brake pad contact surfaces after refinishing or replacing drums or rotors, after replac-
ing pads or linings, or if a soft pedal occurs at very low mileage. Refer to BR-31, "
BRAKE BUR-
NISHING PROCEDURE" .

WARNING:

Clean dust on brake caliper and pad with a vacuum dust collector. Do not blow with compressed
air.
CAUTION:

Never depress brake pedal while removing cylinder body because piston will pop out.

Do not remove brake hose and torque member mounting bolts unless disassembling or replacing
caliper assembly. Hang the cylinder body with a wire so that the brake hose is not under tension.

Be careful not to damage piston boot. Do not allow brake fluid to get the rotor.

When replacing brake pads, always replace inner shims, outer shims, and shim covers as a set.

Removal and InstallationEFS004GR
REMOVAL
Pay attention to the following when removing sensor.
CAUTION:

As much as possible, avoid rotating sensor when removing it. Pull sensors out without pulling on
sensor harness.

Take care to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor
function.
INSTALLATION
Pay attention to the following when installing sensor. Tighten installation bolts to specified torques.

When installing, check that there is no foreign material such as iron chips on pick-up and mounting hole of
the sensor. Check that no foreign material has been caught in the sensor rotor. Remove any foreign mate-
rial and clean the mount.

When installing front sensor, be sure to press rubber grommets in until they lock at the three locations
shown in the figure (2 at strut and 1 at body panel). When installed, harness must not be twisted.

SYSTEM DESCRIPTION

SYSTEM DESCRIPTIONPFP:00000
System DiagramEFS0019X
ESP FunctionEFS0019W
1. The Electronic Stability Program is called the ESP for short.
ESP is indicated as ESP on CONSULT-II screen.
2. In addition to the ABS/TCS function, ESP detects a driver's steering operation amount and brake opera-
tion amount from steering angle sensor and pressure sensor. Using the information from yaw rate/side G
sensor and wheel sensors, ESP judges the driving condition (conditions of understeer and oversteer) to
improve the stability by controlling brake on 4 wheels and engine output.
3. During ESP operation, SLIP indicator lamp flashes to inform the driver of the operation.
CAUTION:

During ESP operation, body and the brake pedal lightly vibrate and their mechanical noise may be
heard. This is a normal condition.

If vehicle is rotated on a turn table, or rolled and rocked on a ship, the ABS warning lamp,
ESP OFF indicator lamp, and SLIP indicator lamp may turn on. In this case, start engine on a nor-
mal road again. If the ABS warning lamp, ESP OFF indicator lamp, and SLIP indicator lamp turn
off after the restart, it is normal.

When driving in a steep slope such as a bank, ABS warning lamp, ESP OFF indicator lamp, and
SLIP indicator lamp may turn on. In this case, start the engine on a normal road again. If ABS
warning lamp, ESP OFF indicator lamp, and SLIP indicator lamp turn off after the restart, it is nor-
mal.
TCS FunctionEFS0019V
1. With the wheel sensor signals from 4 wheels, the ESP/TCS/ABS control unit detects a wheel spin. If a
wheel spins, the control unit controls brake fluid pressure to the spinning wheel, and cuts the fuel to the
engine. It also closes the throttle valve to reduce the engine torque. Furthermore, throttle position is con-
trolled to the appropriate engine torque.
2. If a wheel spins, the TCS system works and function by applying brake fluid pressure to the spinning
wheel.

Removal and InstallationEFS001CD
CAUTION:

Be careful not to damage sensor edge and rotor tooth. Before removing front or rear wheel hub,
remove wheel sensor to avoid sensor wiring damage. Otherwise, sensor may be deactivated.

When removing sensor, avoid rotating it as much as possible. Do not forcibly pull sensor harness.

When installing, check sensor pick-up and mounting hole for foreign material such as iron chips.
Check no foreign material has been caught in sensor rotor. Remove any foreign material found.
Tighten mounting bolts and nuts to the specified torque.
