MODIFIED RT SERIES PARK BRAKE

The Carlisle Brake & Friction Modified RT Series Park Brake is now available to accommodate increased rotor thickness. The Modified RT is a mechanically actuated, sliding caliper brake, designed for static/secondary applications. Both the caliper and disc require fixed mountings. Multiple calipers may be used on a single disc to proportionally increase torque output.
