PRESSURE APPLIED, SPRING RELEASED DISC BRAKES
Dellner Brakes model SKD disc brakes are direct acting, hydraulic or air pressure applied, spring released units. The braking force achieved is directly proportional to the applied pressure.
The brakes consist of two symmetrical halves that accommodate a standard disc thickness of 12 mm. For use with thicker brake discs, the brakes can be supplied with spacers.
Each brake half has two cylindrical guide pins that transmit the tangential braking force from the brake pad to the brake housing and mounting stand. As a result, the brake pistons are not subject to any radial forces which contributes to longer brake life.
Two springs on each brake half retract the brake pads from the disc when pressure is released. Brake pad wear is automatically compensated for with increased piston stroke.
