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 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.
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.
B. Install the new brake pads.
C. Secure the caliper to the knuckle and/or axle
housing with the cap screws. Tighten to 20 ft-lb.
5. Install the wheel. Tighten to 40 ft-lb.
6. Burnish the brake pads (see Burnishing Brake Pads
in this section).

Burnishing Brake Pads

Brake pads 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.
Failure to properly burnish the brake pads could lead to
premature brake pad wear or brake loss. Brake loss can
result in severe injury.
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 levers or
brake pedal to decelerate to 0-5 mph.
3. Repeat procedure on each brake system twenty
times.
4. Verify the brakelights illuminate when the hand lever
is compressed or the brake pedal is depressed.
