over disc and align with mounting holes in mounting
bracket.
2 Thread mounting bolts into mounting bracket, adjusting
bolts until a .020" - .060" gap exists between the Sleeves
(9) and the Locking Nuts. Tighten the Locking Nuts to 75
to 85 lb-ft of torque against the bracket.
3 Refer to Adjustment Procedure to set clearance of installed
brake assembly.

Adjustment Procedure

1 Loosen two Adjustment Nuts (12 & 13) (one full nut and
one jam nut except when using a 0.50 inch thick disc which
requires two jam nuts).
2 Tighten inner Nut (12) until firm contact is made with the
disc by the linings. Torque to 100 lbs in. Make certain Lever
(1) is in proper operating position for application.
3 Back off inner Nut (12) 4 to 5 flats and check that disc is
free to move.
4 Tighten outer Nut (13) against inner Nut (12) to lock
Adjustment Bolt (2) in place. Torque to 45 to 55 lb-ft.
