Draining

CAUTIONDo not spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off immediately and wash with water if it gets on a painted surface. Turn the ignition switch OFF and disconnect ABS actuator and electric unit (control unit) or battery negative terminal before performing work.

  1. Connect a vinyl tube to the bleeder valve.
  2. Depress the brake pedal and loosen the bleeder valve to gradually discharge brake fluid.

Refilling

CAUTIONTurn the ignition switch OFF and disconnect ABS actuator and electric unit (control unit) or battery negative terminal before performing work. Do not spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off immediately and wash with water if it gets on a painted surface. Monitor the brake fluid level in the reservoir while performing the air bleeding procedure. 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. Check that there is no foreign material in the reservoir tank, and refill with new brake fluid. Refer to " «RECOMMENDED FLUIDS AND LUBRICANTS»(ref-675584-S23480474382014120500000) ".
  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 " «BLEEDING BRAKE SYSTEM»(ref-675601-S26412415452014120500000) ".

  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 brake 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 " «BRAKE CALIPER ASSEMBLY: EXPLODED VIEW»(ref-675601-S13560409762014120500000) ". Rear drum brake: Refer to " «EXPLODED VIEW»(ref-675601-S28518891912014120500000) ".
  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 " «INSPECTION»(ref-675601-S37175112292014120500000) ".
  8. Add brake fluid as necessary to keep the brake fluid level within the specified range. Refer to " «RECOMMENDED FLUIDS AND LUBRICANTS»(ref-675584-S23480474382014120500000) ".
  9. Inspect the brake pedal height and play. Adjust it if the measurement value is not the standard. Refer to " «INSPECTION AND ADJUSTMENT»(ref-675601-S07977721252014120500000) ".

FLUID LEAKS

Check for brake fluid leaks from the master cylinder, reservoir tank, and brake tube connections.
