B. Install and secure the cover; then slowly com-
press the brake lever several times.
C. Remove the protective cap, install one end of a
clear hose onto one FRONT bleeder screw, and
direct the other end into a container; then while
holding slight pressure on the brake lever, open
the bleeder screw and watch for air bubbles.
Close the bleeder screw before releasing the
brake lever. Repeat this procedure until no air
bubbles are present.
NOTE: During the bleeding procedure, watch
the reservoir sight glass very closely to make sure
there is always a sufficient amount of brake fluid.
Failure to maintain a sufficient amount of fluid in
the reservoir will result in air in the system.
D. Repeat step C until no air bubbles are observed
in the bleeder line. Close the bleeder screw and
tighten.

cracks or other damage. If found, the brake hoses
must be replaced.
! 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.
MEASURING/REPLACING FRONT
BRAKE 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 the front wheels.
2. Measure the thickness of each brake pad.
