Brake Bleeding / Fluid Change
NOTE: When bleeding the brakes or replacing the
fluid, always start with the caliper farthest from the
master cylinder.
CAUTION
Always wear safety glasses during these procedures.
Brake fluid will damage finished surfaces. Do not allow
brake fluid to come in contact with finished surfaces.
NOTE: Do not remove brake lever when reservoir
fluid level is low.
This procedure should be used to change fluid or bleed
brakes during regular maintenance.
1.
Clean reservoir cover thoroughly.
2.
Remove screws, cover and diaphragm (C) from
reservoir.
3.
Inspect vent slots (A) in cover and remove any debris
or blockage.
4.
If changing fluid, remove old fluid from reservoir with
a Mity Vac® pump (
PN 2870975
) or similar tool.
5.
Begin bleeding procedure with the caliper that is
farthest from the master cylinder. Install a box end
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.
NOTE: Fluid may be forced from supply port (B)
when brake lever is pumped. Place diaphragm
(C) in reservoir to prevent spills. Do not install
cover. See Illustration above.
6.
Slowly pump the brake lever until pressure builds
and holds.
7.
While maintaining lever pressure, open bleeder
screw. Close bleeder screw and release brake lever.
NOTE:
Do not release lever before bleeder
screw is tight or air may be drawn into caliper.
8.
Repeat procedure until clean fluid appears in bleeder
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.
9.
Tighten bleeder screw securely and remove bleeder
hose. Torque the bleeder screw to specification.
Bleeder Screw:
25-30 in-lbs (2.80-3.40 Nm)
