Bleed Rear Brake
NOTE
Hydraulic brake fluid bladder-type pressure equipment can be
used to fill the brake master cylinder through the bleeder
valve if master cylinder reservoir cover is removed to prevent
pressurization.
1. See Figure 1-12. Remove rubber cap and install end of
plastic tubing over rear caliper bleeder valve and place
other end of tubing in a clean container.
CAUTION
D.O.T. 4 brake fluid will damage painted and body panel
surfaces it comes in contact with. Always use caution
and protect surfaces from spills whenever brake work is
performed. Failure to comply can result in cosmetic dam-
age. (00239a)
2. See Figure 1-13. Unscrew cap from rear master cylinder
reservoir.
3. Repeat the following until all air bubbles are purged and
only brake fluid flows from the plastic tubing.
a. With motorcycle upright, add D.O.T. 4 BRAKE
FLUID to master cylinder reservoir until the level is
between upper and lower marks on reservoir.
NOTE
Do not reuse brake fluid.
b. Slowly depress and release brake pedal several
times to build up hydraulic pressure, then hold brake
pedal in the depressed position.
c. While holding brake pedal in the depressed position,
open bleeder valve about 1/2-turn counterclockwise.
Brake fluid will flow from bleeder valve and through
tubing into container.
d. When brake pedal has moved 1/2 to 3/4 of its range
of travel, close bleeder valve (clockwise).
e. Allow brake pedal to return slowly to its released
position.
4. Tighten rear caliper bleeder valve to 36-60 in-lbs (4-
7 Nm) and replace the rubber cap.
5. Verify brake fluid level is between the upper and lower
lines on the side of the reservoir.
6. Thread cap on reservoir and tighten securely.
