3. To bleed the brake system, use the following
procedure.
A. Remove the cover and fill the reservoir with
DOT 4 Brake Fluid (p/n 1639-799).
B. Install and secure the cover; then slowly
compress 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 proce-
dure 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.
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 sys-
tem 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
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.
