reservoir. The amount of brake fluid supplied to the r
ear LH wheel cylinder from the master cylinder is con-
trolled according to time that the ABS IN valve is not energized (time that the ABS IN valve is open).
Brake Release
Front RH brake caliper
• Brake fluid is supplied to the front RH brake caliper through the return check valve of the ABS IN valve and
the cut valve 1, and returns to the master cylinder.
Front LH brake caliper
• Brake fluid is supplied to the front LH brake caliper through the return check valve of the ABS IN valve and the cut valve 2, and returns to the master cylinder.
Rear RH wheel cylinder
• Brake fluid is supplied to the rear RH wheel cylinder through the return check valve of the ABS IN valve and
the cut valve 2, and returns to the master cylinder.
Rear LH wheel cylinder
• Brake fluid is supplied to the rear LH wheel cylinder through the return check valve of the ABS IN valve and
the cut valve 1, and returns to the master cylinder.

• Turns ON when VDC and TCS functions are switched to non-operational status (OFF) by VDC OFF switch.
• Turns ON when ignition switch turns ON and turns OFF when the system is normal, for bulb check purposes.
CONDITIONS FOR WARNING LAMP ILLUMINATION
Turns ON when ignition switch turns ON and turns OFF when the system is normal, for bulb check purposes.
Component Function
Pump Returns the brake fluid reserved in reservoir to master cylinder by reducing pressure.
Motor Activates the pump according to signals from ABS actuator and electric unit (control unit).
Cut valve 1
Cut valve 2 Shuts off the ordinary brake line from master cylinder.
Suction valve 1
Suction valve 2 Supplies the brake fluid from master cylinder to the pump.
ABS IN valve Switches the fluid pressure line to increase or hold according to signals from control unit.
ABS OUT valve Switches the fluid pressure line to increase, hold or decrease according to signals from control unit.
Return check valve Returns the brake fluid from brake caliper and wheel cylinder to master cylinder by bypassing orifice
of each valve when brake is released.
Reservoir Temporarily reserves the brake fluid drained from brake caliper, so that pressure efficiently decreas-
es when decreasing pressure of brake caliper and wheel cylinder.
Pressure sensor Detects the brake fluid pressure and tr ansmits signal to ABS ac tuator and electric unit (control unit).

CHASSIS AND BODY MAINTENANCE
1. Check that there is no foreign material in the reservoir tank, andrefill with new brake fluid. Refer to MA-11, "
Fluids and Lubri-
cants".
2. Loosen the bleeder valve, slowly depress the brake pedal to the full stroke, and then release the pedal. Repeat this operation at
intervals of 2 or 3 seconds until new brake fluid is discharged.
Then close the bleeder valve with the brake pedal depressed.
Repeat the same work on each wheel.
3. Perform the air bleeding procedure. Refer to MA-36, "
BRAKE
FLUID : Bleeding Brake System".
BRAKE FLUID : Bleeding Brake SystemINFOID:0000000012432283
CAUTION:
• Turn the ignition switch OFF and disconnect ABS act uator and electric unit (control unit) or battery
negative terminal before performing the work.
• Monitor the fluid level in the reservoir tank while performing the air bleeding.
• Do not spill or splash brake fluid on painted su rfaces. Brake fluid may seriously damage paint. Wipe
it off immediately and wash with wa ter if it gets on a painted surface.
• Always use new brake fluid for refilling. Do not reuse drained brake fluid.
• Do not allow foreign matter (e.g. dust) and oils other than brake fluid to enter the reservoir tank.
1. Connect a vinyl tube to the bleeder valve.
2. Fully depress the brake pedal 4 to 5 times.
3. Loosen the bleeder valve and bleed air with the br ake pedal depressed, and then quickly tighten the
bleeder valve.
4. Repeat steps 2 and 3 until all of the air is out of the brake line.
5. Tighten the bleeder valve to the specified torque. • Front disc brake: Refer to BR-36, "
BRAKE CALIPER ASSEMBLY : Exploded View".
• Rear drum brake: Refer to BR-41, "
Exploded View".
6. Perform steps 1 to 5 in the following order: Front (RH) brake → front (LH) brake → rear (RH) brake → rear
(LH) brake.
7. Check that the fluid level in the reservoir tank is within the specified range after air bleeding. Refer to MA-
35, "BRAKE FLUID : Inspection".
8. Add brake fluid as necessary to keep the brake fluid level within the specified range. Refer to MA-11, "
Flu-
ids and Lubricants".
9. Inspect the brake pedal height and play. Adjust it if the measurement value is not the standard. Refer to
BR-9, "
Inspection and Adjustment".

DISC BRAKE : Brake BurnishingINFOID:0000000012432285
BRAKE BURNISHING
Burnish contact surfaces between disc brake rotor and brake pads according to the following procedure after
refinishing disc brake rotors, replacing disc brake rotors,
replacing brake pads, or if a soft pedal occurs at very
low mileage:
CAUTION:
• Be careful of vehicle speed because the brake peda l does not operate firmly/securely until pads and
disc brake rotor are securely seated.
• Only perform this procedure under safe road and traffic conditions. Use extreme caution.
1. Drive vehicle on straight, flat road.
2. Depress brake pedal with the power to stop vehicle within 3 to 5 seconds until the vehicle stops.
3. Drive without depressing brake pedal for a few minutes to cool the brakes.
4. Repeat steps 1 to 3 until pad and disc brake rotor are securely seated.
DISC BRAKE : InspectionINFOID:0000000012432286
INSPECTION
Appearance
Check surface of disc brake rotor for uneven wear, cra cks, and serious damage. Replace it if necessary. Refer
to BR-45, "
Front Disc Brake".
Runout
1. Secure the disc brake rotor to the wheel hub with wheel nuts (2
points at least).
2. Check the wheel bearing axial end play before the inspection. Refer to FA X - 7 , "
Inspection".
3. Inspect the runout with a dial indicator to measure at 10 mm (0.39 in) inside the disc edge.
4. Find the installation position that has a minimum runout by shift-
ing the disc brake rotor-to-wheel hub installation position by one
hole at a time if the runout exceeds the limit value.
5. Refinish or replace the disc brake rotor if the runout is outside the limit even after performing the above
operation.
CAUTION:
If the thickness is less than w ear thickness + 0.3 mm (0.012 in), replace the disc brake rotor. Refer
to BR-37, "
BRAKE CALIPER ASSEMBLY : Removal and Installation".
Thickness
Check the thickness of the disc brake rotor using a micrometer.
Replace the disc brake rotor if the thickness is below the wear limit.
Refer to BR-45, "
Front Disc Brake".
DRUM BRAKE
Runout : Refer to BR-45, "Front Disc Brake".
Wear thickness : Refer to BR-45, "
