Maintenance

Brake Adjustment

If excessive brake lever to brake block clearance is evident, the brake
cable should be adjusted. If proper adjustment cannot be achieved by
using the following methods, check the brake band for excessive wear.
Your snowmobile dealer can install a new brake band when necessary.
Improper brake adjustment can result in brake failure, which could
result in severe injury or death. Perform the adjustment procedures
exactly as outlined or see your Polaris dealer for service.
1. Slide the two rubber protector
covers (A) back to expose the cable
adjuster.
2. Using an 8mm wrench to hold the
barrel nut (B), loosen the jam nut
(C) with a 10mm wrench.
3. With your left hand, grasp the
cables (D) as close to the adjuster
as possible. Use your right hand to
rotate the barrel nut until you have
reached the proper brake lever adjustment.
4. Check the actuator linkage to
ensure there is adequate freedom
of movement for positive brake
operation and that all floating parts
move freely and that all parts are
mounted securely. Tighten
hardware as required.
5. Tighten the adjuster jam nut and
slide the rubber protectors back onto the adjuster.
6. The brake band is adjusted correctly when there's 1/4" - 3/8"
(6-10mm) brake lever freeplay and clearance between the brake
lever and block with the lever fully depressed is no more than 3/4"
(1.9cm). Torque the band bolt nut to 6 ft. lbs. (83 kg 2-m)
