
NOTE: During the bleeding procedure, watch the
reservoir sight glass very closely to make sure
there is always a sufficient amount of brake fluid.
When the sight glass changes from dark to light,
refill the reservoir before the bleeding procedure is
continued. Failure to maintain a sufficient amount
of fluid in the reservoir will result in air in the sys-
tem.
D. Repeat step C until the brake lever is firm.
E. At this point, perform step B, C, and D on the
other FRONT bleeder screw; then move to the
REAR bleeder screw and follow the same
procedure.
4. Carefully check the entire hydraulic brake system
that all hose connections are tight, the bleed
screws are tight, the protective caps are installed,
and no leakage is present.
! CAUTION
This hydraulic brake system is designed to use
high-temperature DOT 4 brake fluid only. If brake
fluid must be added, care must be taken as brake
fluid is very corrosive to painted surfaces.
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
thickness of each of the brake pads as follows.
1. Remove a front wheel.
2. Measure the thickness of each brake pad.
730-434B
3. If thickness of either brake pad is less than 3.2 mm
(0.125 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 pro-
cedure.
A. Remove the wheel.
B. Remove the cap screws securing the caliper to
the bracket; then remove the cotter pin securing
the pads and remove the pads.
C. Install the new brake pads; then secure with the
pin and cotter pin. Spread the cotter pin.
D. Secure the caliper to the knuckle and/or axle
housing with the cap screws. Tighten to 2.8
kg-m (20 ft-lb).
