W.C. Branham's spring applied caliper disc brakes function opposite of traditional brakes. Normal brake operation requires active pressure to brake and pressure removed to release. PFS Series requires active minimum pneumatic pressure of 85 psi to release. At a loss of pressure, energy stored in the Belleville spring stack(s) take over to stop or hold the mass.

Ideal for emergency stopping or holding of industrial machinery.
