Turn adjusting screw (9) clockwise until the brake pads are no longer loose and the torque on adjusting screw (9) does not exceed 13.6 N m (120.37 lb in). Back off adjusting screw (9) 3 turns.
First adjust the brake pad closest to the axle using a 2.0 mm (0.07874 inch) feeler gauge check the brake pad to disc clearance.

Adjust bolt (8) until bolt (8) comes in contact with mounting plate (13). Be sure that the 2.0 mm (0.07874 inch) feeler gauge is still in place. Tighten bolt (8) until the feeler gauge is slightly tight. Hold bolt (8) and tighten nut (12) to a torque of 44 4 N m (32 3 lb ft). Next, adjust the second brake pad by turning bolt (9) until running clearance between pad and disc is 2.0 mm (0.07874 inch).
