Adjusting Multi-Disc Brakes

Brief general information on adjusting multi-disc brakes

Multi-disc brakes, wet.

• Wet multi-disc brakes are adjusted using a wedge-shape actuator that is operated by springs, air or hydraulics.
• The wedge moves different distances, always on the return stroke. The method varies depending on the manufacturer.
• The piston transfers force via a roller bearing to threaded pistons that rotate on the return stroke.
• Multi-disc brakes with annular pistons provide a large annular area. These are generally used with working pressures as low as 30–40 bar.
• External adjuster stop that can be moved.

Typical applications:

• Large heavy vehicles
• Dumper trucks
• Mobile cranes
