FRONT DISC BRAKE
ASSEMBLY
CAUTION:
When assembling, use only rubber lubricant specified below.
1. Apply polyglycol ether based lubricant to the piston seal, and
install them to the cylinder body.
2. Apply brake fluid to piston and apply rubber grease to piston
boot.Coverthepistonendwiththepistonboot,andtheninstall
cylinder side lip of the piston boot securely into the groove on
cylinder body.
3. Insert piston into cylinder body by hand and insert piston boot
piston-side lip into the piston groove.
CAUTION:
Press the piston evenly and vary the pressing point to pre-
vent cylinder inner wall from being rubbed.
4. Install sliding pin and sliding pin boot to torque member.
5. If pad assemblies are removed, install pad assemblies to torque member. Refer toBR-25, "
Removal and
Installation of Brake Pad".
6. Install cylinder body to torque member, and then tighten sliding pin bolt to the specified torque. Refer to
BR-24, "
Components".
DISC ROTOR INSPECTION
Visual Inspection
Check surface of disc rotor for uneven wear, cracks, and serious damage. If any of them is detected, replace
applicable part.
Runout Inspection
1. Using wheel nuts, secure disc rotor to wheel hub. (2 or more positions)
2. Check runout using a dial indicator.
[measured at 10 mm (0.39 in) inside the disc edge]
CAUTION:
Make sure that wheel bearing axial end play is within the
specifications before measuring runout. Refer toFAX-5,
"WHEEL BEARING INSPECTION".
3. If runout is outside the limit, find the minimum runout point by
shifting mounting positions of disc rotor and wheel hub by one
hole.
4. If runout is still out of the specification, refinish the disc rotor with
on-car brake lathe (“MAD, DL-8700”, “AMMCO 700 and 705” or equivalent). Or replace the disc rotor.

For Fast and Accurate DiagnosisEFS005TX
PRECAUTIONS FOR DIAGNOSIS
lBefore performing diagnosis, always read precautions. Refer toBRC-17, "CONSULT- II Functions".
lAfter diagnosis is finished, be sure to erase memory. Refer toBRC-18, "ERASE MEMORY".
lWhen checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector termi-
nals.
lFor intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.
lIf a circuit tester is used for check, be careful not to forcibly extend any connector terminal.
lABS system electrically controls brake operation and engine output. Following symptoms may be caused
by normal operations:
Basic InspectionEFS005TY
BASIC INSPECTION 1 BRAKE FLUID LEVEL, LEAKS, AND BRAKE PADS
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill brake fluid.
2. Check brake tube and around ABS actuator and electric unit (control unit) for leaks. If leakage or seepage
is found, check the following items.
lIf ABS actuator and electric unit (control unit) connection is loose, tighten brake tube to the specified
torque and re-conduct the leak inspection to make sure there are no leakage.
lIf there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw,
replace the damaged part and re-conduct the leak inspection to make sure there are no leakage.
lIf there is leakage or seepage at any location other than ABS actuator and electric unit (control unit)
connection, wipe away leakage or seepage with clean cloth. Then inspect again and confirm than there
is on leakage.
lIf there is leakage from ABS actuator and electric unit (control unit), wipe away leakage or seepage with
clean cloth. Then inspect again. If there is leakage or seepage, replace ABS actuator and electric unit
(control unit).
CAUTION:
ABS actuator and electric unit (control unit) body cannot be disassembled.
3. Check brake pad degree of wear. Refer toBR-24, "
PAD WEAR INSPECTION"in “Front Disc Brake” and
BR-32, "
Lining Thickness Inspection"in “Rear Drum Brake”.
BASIC INSPECTION 2 POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure battery positive cable, negative cable and ground connection are not loose. In addition, check the
battery voltage to make sure it has not dropped and alternator is normal.
Symptom Symptom description Result
Motor operation noiseThis is noise of motor inside ABS actuator and electric unit (control unit). Slight
noise may occur during ABS operation.
Normal
Just after engine starts, motor operating noise may be heard. This is a normal
status of the system operation check.
System operation check noiseWhen engine starts, slight “click” noise may be heard from engine compart-
ment. This is normal and is part of system operation check.Normal
ABS operation
(Longer stopping distance)When driving on roads with a low coefficient of friction, such as snowy roads
or gravel roads, the stopping distance is sometimes longer for vehicles
equipped with ABS. Therefore, when driving on such roads, drive at a suffi-
ciently reduced speed to be safe.Normal

Air Bleeding ProcedureECS00ICI
NOTE:
Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum assist or
power bleeder will not purge all the air from the system.
CAUTION:
lMonitor clutch fluid level in reservoir tank to make sure it
does not empty.
lKeep painted surface on the body or other parts free of
clutch fluid. If it spills, wipe up immediately and wash the
affected area with water.
lFor RHD models: Bleed air for operating cylinder.
lFor LHD models: Bleed air for clutch connector first, and then for
operating cylinder.
1. Fill reservoir tank with new clutch fluid.
2. Connect a transparent vinyl hose to air bleeder valve.
3. Depress clutch pedal slowly and fully several times at an interval
of 2 to 3 seconds and hold it.
4. With clutch pedal depressed, open air bleeder valve to release
air.
5. Close air bleeder valve.
6. Release clutch pedal and wait for 5 seconds.
7. Repeat steps 3 to 6 until no bubbles can be observed in clutch
fluid.
8. Tighten air bleeder valve to the specified torque. Refer toCL-11,
"Components"andCL-13, "Removal and Installation".
