Changing Brake Fluid

CAUTIONRefill with new brake fluid. Refer to RECOMMENDED FLUIDS AND LUBRICANTS . Always keep fluid level higher than minimum line on reservoir tank. Never 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.
  1. Connect a vinyl tube and container to the air bleeder.
  2. Depressing the brake pedal, drain the brake fluid gradually from the air bleeder of each wheel.
  3. Turn the ignition switch to OFF and disconnect the ABS actuator and control unit connector or battery ground cable.
  4. Clean inside of reservoir tank, and refill with new brake fluid.
  5. Loosen the air bleeder, depress the pedal slowly to the full stroke and then release it. Repeat the procedure every 2 or 3 seconds until the new brake fluid comes out, then close the air bleeder while depressing the pedal. Refer to «BLEEDING BRAKE SYSTEM»(ref-233670-S10819733002006052600000) .
CAUTIONCarefully monitor brake fluid level at master cylinder during bleeding operation. Fill reservoir with new brake fluid RECOMMENDED FLUIDS AND LUBRICANTS . Make sure it is full at all times while bleeding air out of system. Place a container under master cylinder to avoid spillage of brake fluid. Do not loosen the connecting portion of the actuator during air bleeding.

  1. Turn ignition switch OFF and disconnect ABS actuator and control unit connector or battery ground cable.
  2. Connect a transparent vinyl tube and container to air bleeder valve.
  3. Fully depress brake pedal several times.
  4. With brake pedal depressed, open air bleeder valve to release air.
  5. Close air bleeder valve.
  6. Release brake pedal slowly.
  7. Tighten air bleeder valve to specification. Air bleeder valve: 7 - 9 N.m (0.7 - 0.9 kg-m, 61 - 78 in-lb)
  8. Repeat steps 2. through 7. until no more air bubbles come out of air bleeder valve.
  9. Bleed the brake hydraulic system air bleeder valves in the following order: Right rear brake -> Left front brake -> Left rear brake -> Right front brake
