Front Brakes
Removing (Fig. 6)
1. Park machine on a level surface, stop spray pump, stop
engine and engage parking brake. Remove key from igni-
tion switch.
2. For front brake that is to be serviced, remove wheel as-
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.
3. If brake caliper is to be removed from vehicle, thorough-
ly clean junction of brake line and caliper. Loosen and re-
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).
Installing (Fig. 6)
1. Thoroughly clean all front brake components before as-
sembly.
2. Install the front wheel hub and brake rotor if they were

line fitting.

washers and then thread into caliper. Tighten banjo bolt

from 75 to 80 ft- lb (102 to 108 N- m).
6. Install wheel assembly to vehicle (see Wheel As-
semblies in this chapter).

CAUTION
After servicing the brakes, always check the
brakes in a wide open, level area that is free of
other persons and obstructions.

Burnish Brake Pads
After brake pad replacement, burnish (break- in) the
brakes before use.
1. Bring the machine to full speed and apply the brakes to
rapidly stop the machine without skidding or locking up the
wheels.
2. Repeat this procedure 10 times. To avoid overheating
the brakes, wait 1 minute between each stop.
