Drain and Refill

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 harness connector from the ABS actuator and electric unit (control unit) or negative battery terminal. Refer to Removal and Installation.

• Refill brake system with new brake fluid. Refer to Fluids and Lubricants.

• Do not reuse drained brake fluid.

DRAINING

Turn ignition switch OFF and disconnect the harness connector from the ABS actuator and electric unit (control unit) or negative battery terminal. Refer to Removal and Installation.

Connect a vinyl tube to bleeder valve.

Depress brake pedal, loosen bleeder valve, and gradually remove brake fluid.

CAUTION:

Do not allow reservoir tank to empty as this may cause damage to master cylinder internal components.

REFILLING

Make sure no foreign material is in the reservoir tank or sub tank, 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 sub tank frequently.

CAUTION:

Do not allow reservoir tank to empty as this may cause damage to master cylinder internal components.

Bleed the air out of the brake hydraulic system. Refer to Bleeding Brake System.

CAUTION:

• While bleeding, pay attention to brake fluid level.

• Do not allow reservoir tank to empty as this may cause damage to master cylinder internal components.

• Before working, disconnect the harness connector from the ABS actuator and electric unit (control unit) or negative battery terminal. Refer to Removal and Installation.

Turn ignition switch OFF and disconnect the harness connector from the ABS actuator and electric unit (control unit) or negative battery terminal. Refer to Removal and Installation.

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 Exploded View (front disc brake), Exploded View (rear disc brake).

Repeat steps 2 through 6, with sub tank filled at least halfway. Bleed the air in the following order from the front (RH), front (LH), rear (RH), rear (LH).
