SAHR RT SERIES PARK BRAKE

The Carlisle Brake & Friction Spring Applied Hydraulic Release (SAHR) RT Series Park Brake Brake is a failsafe, spring applied hydraulic released sliding caliper, designed for static/secondary applications. Both the caliper and disc require fixed mountings. Multiple calipers may be used on a single disc to proportionately increase torque output.

Additional Product Details
