CAUTION:
- Do not spill or splash brake fluid on painted surfaces. Brake
fluid may damage paint. If brake fluid is
splashed on painted areas, wash it away with water immediately.
- Prior to repair, turn the ignition switch OFF, disconnect the ABS
actuator and electric unit (control
unit) connector or negative battery terminal. Refer to PG-50, "Exploded
View".
- Refill brake system with new brake fluid. Refer to MA-11, "Fluids

- Do not reuse drained brake fluid.
DRAINING
- Turn ignition switch OFF and disconnect ABS actuator and electric unit
(control unit) connector or negative
battery terminal. Refer to PG-50, "Exploded View".
- Connect a vinyl tube to bleeder valve.
- Depress brake pedal, loosen bleeder valve, and gradually
remove brake fluid.

REFILLING
- Make sure no foreign material exists in the reservoir and refill with
new brake fluid.
CAUTION:
Do not reuse drained brake fluid.
- Refill the brake system as follows:
- Depress the brake pedal.
- Loosen bleeder valve.
- Slowly depress brake pedal to 2/3 of the brake pedal full stroke.
- Tighten bleeder valve.
- Release brake pedal.
Repeat this operation at intervals of two or three seconds until all old
brake fluid is discharged. Add new
brake fluid to master cylinder reservoir sub tank frequently.
CAUTION:
Do not allow master cylinder reservoir to empty as this may cause
damage to master cylinder
internal components.
- Bleed the air out of the brake hydraulic system. Refer to BR-17,
"Bleeding Brake System".
Bleeding Brake System
CAUTION:
Do not spill or splash brake fluid on painted surfaces. Brake fluid may
damage paint. If brake fluid is
splashed on painted areas, wash it away with water immediately.
While bleeding, pay attention to master cylinder fluid level.
Before working, disconnect ABS actuator and electric unit (control
unit) connectors or negative battery
terminal. Refer to PG-50, "Exploded View".
- Turn ignition switch OFF and disconnect ABS actuator and electric unit
(control unit) connector or negative
battery terminal. Refer to PG-50, "Exploded View".
- Connect a vinyl tube to rear right brake bleeder valve.
- Fully depress brake pedal 4 or 5 times.
- With brake pedal depressed, loosen bleeder valve to bleed air in brake
line, and then tighten it immediately.
- Repeat steps 3 and 4 until all of the air is out of the brake line.
- Tighten the bleeder valve to the specified torque. Refer to BR-40,
"BRAKE CALIPER ASSEMBLY :
