1. Park machine on a level surface, stop spray pump, stop
engine and engage parking brake. Remove key from igni-

sembly from vehicle (see Wheel Assemblies in this chap-
ter). Make sure that vehicle is supported with jack stands.
NOTE: Brake caliper can be removed from brake rotor
without removing brake line from caliper. Support the brake
caliper with a cable tie or wire once the brake caliper is re-
moved from the machine. DO NOT allow the brake caliper
to hang by the brake hose.

move banjo bolt from caliper and separate brake line from
caliper. Discard sealing washers.
4. Remove two (2) cap screws and lock washers that se-
cure brake caliper to the front spindle. Slide caliper from
brake rotor. If front brake calipers need to be serviced, see
Brake Caliper Service in this chapter.
5. Inspect brake pads for wear or damage. Minimum
brake pad thickness is 1/16" (1.6 mm).
6. Inspect brake rotor for wear or damage. Minimum brake
rotor thickness is 0.154" (3.9 mm).
NOTE: If front brake rotor needs to be removed, removing
the wheel hub assembly is required (see Front Wheel Hubs
in this chapter for additional information).

sembly.

rapidly stop the machine without skidding or locking up the
