
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.
PR377C
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 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.
PR237
B. Install the new brake pads.

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.
