Manual Bleeding the Brakes
- Remove the booster reserve by applying the brakes several times with the engine OFF until all the reserve is depleted.
- Fill the master cylinder reservoir with brake fluid. Keep the master cylinder at least one-half full of fluid during the bleeding operation.
- Disconnect the front brake line(s) at the master cylinder.
- Allow the brake fluid to fill the master cylinder until it begins to flow from the front pipe connector port.
- Connect the front brake line(s) to the master cylinder.
Tighten:
Tighten the brake lines to 16 N.m (12 lb-ft).
- Slowly push and hold the brake pedal one time.
See Fig 1.
- Loosen the front brake line at the master cylinder to purge air from the cylinder.
- Tighten the brake line (as in Step 5), and then release the brake pedal slowly. Wait 15 seconds before proceeding to the next step.
- Repeat the sequence, including the 15-second wait, until all the air is removed from the master cylinder bore.
See Fig 3.
- After all the air has been removed at the forward connection(s), bleed the master cylinder at the rear (cowl) connection(s) in the same manner as with the front connections.
- Attach a transparent tube over the valve. Allow the tube to hang submerged in brake fluid in a transparent container.
- Slowly push and hold the brake pedal one time.
- Remove the bleeder valve dust cover and loosen the bleeder screw to purge the air from the cylinder.
- Tighten the bleeder screw.
Tighten:
Tighten the bleeder screw to 8 N.m (71 lb-in).
- Slowly release the brake pedal. Wait 15 seconds before proceeding with the next step.
- Repeat the sequence, including the 15-second wait, until all the air is removed. It may be necessary to repeat the sequence 10 or more times to remove all the air.
- Locate the front bleeder caps.
- Proceed to bleed the front brakes following the appropriate sequence, beginning with Step 12.
- Check the brake pedal for sponginess. Repeat the entire bleeding procedure to correct this condition.
- Replace the bleeder valve dust cover.
