Bleeding Sequence
Bleed at each caliper in succession beginning with the
passenger side rear wheel, which is farthest from the
master cylinder. After the rear passenger caliper, move to
the driver side rear wheel, then to the passenger side
front wheel, and finish with the driver side front wheel.
Never use any excess fluid or return
it to the original container. Discard
brake fluid properly.
NOTICE: An assistant is necessary to perform this
procedure.
Use a clean cloth to clean the master cylinder reservoir
and caliper bleeder valves (Ref. Fig. 5). Clean each fitting
before opening to prevent contamination of the system.
Fig. 5 Bleeder Valve
Fill the master cylinder reservoir to within 1/4” (6 mm) of
the top with new DOT 4 brake fluid before starting, and
after bleeding is complete.
Check the master cylinder fluid level frequently during
bleeding and keep the reservoirs at least half full.
The following steps apply to one bleeder screw. Repeat at
both bleeder points.
1.
Attach a bleeder hose to the bleeder screw. Put the
other end of the hose in a glass container partially
filled with brake fluid (Ref. Fig. 5).
NOTICE: Be sure that the free end of the hose is
submerged in brake fluid. This shows air bubbles as
they come out of the system, and prevents air from
being sucked into the system through the bleeder
screw.
2.
Apply moderate (40 - 50 lbs. [18 - 23 kg]), steady
pressure on the brake pedal and open the bleeder
screw.
Do not force the brake pedal to the
floor. The operating rod jam nut can
be forced into the master cylinder where it can dam-
age internal components.
3.
If the brake pedal goes to the floorboard without
removing all of the air bubbles, close the bleeder
screw and release the brake pedal slowly. Repeat
steps 1 and 2.
NOTICE: The bleeder valve at the wheel cylinder
must be closed at the end of each stroke, and
before the brake pedal is released to ensure that air
cannot enter the system. It is also important that the
brake pedal be returned to the full released position.
4.
When fluid coming from the submerged end of the
hose is clear and free of bubbles, close the bleeder
screw and release the brake pedal.
5.
Tighten the bleeder screw to the maximum torque
value specified below.
Flushing
The process of removing old brake fluid to remove water,
mineral oil, or other contaminants from the system is
called flushing the hydraulic system.
Flushing is similar to bleeding except that a greater
amount of brake fluid is discharged from each bleeder
point to make sure that all of the dirty or contaminated
fluid is removed.
The total fluid capacity for the entire hydraulic brake sys-
tem is 13 fl. oz. It is recommended to have at least 26 fl.
oz. of DOT 4 brake fluid on hand when flushing.
