5. 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.
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.
NOTE: As brake pads wear, it may be necessary to
“top-off” the brake fluid in the reservoir.
1. Remove a front wheel.
2. Measure the thickness of each brake pad.
3. If thickness of either brake pad is less than 1.0 mm
(0.039 in.), the brake pads must be replaced.
PR376B
NOTE: The brake pads should be replaced as a set.
4. To replace the brake pads, use the following procedure.
A. Remove the wheel.
B. Remove the cap screws securing the caliper
holder to the knuckle; then remove the pads.
PR237
C. Install the new brake pads.
D. Secure the caliper to the knuckle and/or axle
housing with new “patch-lock” cap screws.
Tighten to 20 ft-lb.
PR377B
E. Install the wheel. Tighten to 40 ft-lb (steel
wheels) or 80 ft-lb (aluminum wheels).
5. Burnish the brake pads (see Burnishing Brake Pads
in this section).
Burnishing Brake Pads
Brake pads (both main and auxiliary) must be burnished
to achieve full braking effectiveness. Braking distance
will be extended until brake pads are properly burnished.
To properly burnish the brake pads, use the following
procedure.
1. Choose an area large enough to safely accelerate the
ATV to 30 mph and to brake to a stop.
2. Accelerate to 30 mph; then compress brake lever or
apply the auxiliary brake to decelerate to 0-5 mph.
3. Repeat procedure on each brake system twenty
times.
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.
! WARNING
Failure to properly burnish the brake pads could lead to
premature brake pad wear or brake loss. Brake loss can
result in severe injury.
