• Check that the brake fluid level in the reservoir tank is within speci-

fication, between the MAX and MIN lines as shown.

• Visually check around reservoir tank for fluid leaks.

• If fluid level is excessively low, check brake system for leaks.

• If brake warning lamp remains illuminated after the parking brake

• Do not reuse drained brake fluid.

• Be careful not to splash brake fluid on painted areas; it may cause paint damage. If brake fluid is

splashed on painted areas, wash it away with water immediately.

• Before servicing, disconnect ABS actuator and electric unit (control unit) connector or battery nega-

tive terminal.

1. Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector or battery

negative terminal.

2. Connect a vinyl tube to each bleed valve.
3. Depress brake pedal, loosen each bleed valve, and gradually

remove brake fluid.

4. Make sure there is no foreign material in reservoir tank, and refill

with new brake fluid.

5. Rest foot on brake pedal. Loosen bleed valve. Slowly depress

brake pedal until it stops. Tighten bleed valve. Release brake

pedal. Repeat the process a few times, then pause to add new

brake fluid to master cylinder. Continue until the new brake fluid

flows out of the bleed valve.

Bleed the air out of the brake hydraulic system. Refer to
