between brake pad and belts, follow these steps:
a. To increase brake pad gap, loosen idler
adjustment nut, and move idler away from
belt. Position idler to achieve a 1/16 in. (1.6
mm) minimum brake pad gap and a 1/2 in.

adjust as necessary to achieve a 7/16 – 9/16
in. (11.1 – 14.3 mm) spring extension.
c. If the cable needed adjustment, recheck gaps
described in step 2a. Repeat steps as
necessary until brake clearance, roller gap
and spring extension are within specified
ranges.
IMPORTANT: If adjustments cannot be brought into
specified ranges see your Dealer for repairs.
