CAUTION
Brake fluid will damage finished surfaces. Do not allow
brake fluid to come in contact with finished surfaces.
This procedure should be used to change fluid or bleed
brakes during regular maintenance.

remove the cover.

wrench on caliper bleeder screw. Attach a clean,
clear hose to fitting and place the other end in a
clean container. Be sure the hose fits tightly on
fitting.

pressure builds and holds.
6. Hold brake pedal on to maintain pedal pressure, and
open bleeder screw. Close bleeder screw and
release foot pedal.
NOTE
Do not release foot pedal before bleeder screw is tight
or air may be drawn into master cylinder.

hose and all air has been purged. Add fluid as
necessary to maintain level in reservoir.
CAUTION
Maintain at least 1/2"(1.27 cm) of brake fluid in the
reservoir to prevent air from entering the master
cylinder.
