2. Depress the brake pedal several times to check for a
firm brake. If the brake is not firm, the system must
be bled. To bleed the brake system, use the following
procedure.
A. Remove the cover and fill the reservoir with DOT 4
brake fluid; then install and secure the cover.
B. Slowly depress the brake pedal several times.
C. Install one end of a clear hose onto the RIGHT
REAR bleeder screw and direct the other end into a
container; then while holding slight pressure on the
brake pedal, open the bleeder screw and watch for air
bubbles. Close the bleeder screw before releasing the
brake pedal. Repeat this procedure until no air bub-
bles are present.

NOTE: During the bleeding procedure, watch the
reservoir very closely to make sure there is always a
sufficient amount of brake fluid. When the level falls
below MIN, refill the reservoir before the bleeding
procedure is continued. Failure to maintain a suffi-
cient amount of fluid in the reservoir will result in air
in the system.
D. At this point, perform steps B and C on the REAR
LEFT bleeder screw; then move to the FRONT
RIGHT bleeder screw and follow the same proce-
dure. Finally, complete the procedure on the FRONT
LEFT bleeder screw.

E. Repeat steps B and C until the brake pedal is firm.
3. Carefully check the entire hydraulic brake system to
ensure all hose connections are tight, the bleed
screws are tight, the protective caps are installed, and
no leakage is present.
INSPECTING HOSES
Carefully inspect the hydraulic brake hoses for cracks or
other damage. If found, the brake hoses must be replaced.
CHECKING/REPLACING PADS
The clearance between the brake pads and brake discs is
adjusted automatically as the brake pads wear. The only
maintenance that is required is replacement of the brake
pads when they show excessive wear. Check the thick-
ness of each of the brake pads as follows.
1. Remove the wheel corresponding to the brake being
checked.
2. Measure the thickness of each brake pad.
PR376A
3. If thickness of either brake pad friction material is
less than 1.0 mm (0.039 in.), the brake pads must be
replaced.
NOTE: The brake pads should be replaced as a set.
4. To replace the brake pads, use the following proce-
dure.
A. Remove the cap screws securing the caliper holder to
the knuckle; then remove the pads from the caliper.
CAUTION
This hydraulic brake system is designed to use DOT 4
brake fluid only. If brake fluid must be added, care must
be taken as brake fluid is very corrosive to painted sur-
faces.
