Hydraulic braking torques:
- Dynamic torque (inch/lb): 144 lbf per 100 psi x braking radius
- Parking/static torque (inch/lb): 72 lbf per 100 psi x braking radius
Mechanical braking torques:
- Dynamic torque (inch/lb) 2.69 x Lever Force (lb.) x braking radius
- Parking/static torque 1.75 x Lever Force (lb) per x braking radius
Cam Lever Travel Data:
- 15º maximum lever travel when friction pads are new and with 1/32" gap on each side of disc.
- Periodic tightening of lock nut will reduce travel of lever and will allow 1/4" wear on each friction pad.
- 90º maximum lever travel after 3/16" wear on each friction pad and without intermediate tightening of lock nut.
