ABSTRACT:
A brake effective between a rotating part and a non-rotating part has a substantially nondeformable brake disk secured to one of the parts, centered on an axis, and having a pair of axially oppositely directed brake-disk faces. A housing is secured to the other of the parts, at least partially surrounds the brake disk, and has a pair of end walls having wall faces axially confronting the respective disk faces. Respective brake elements are limitedly axially displaceable between the wall faces and the respective disk faces and engageable with the respective disk faces. Formations on the elements and housing prevent the elements from rotating relative to the housing. Spring packs between the brake elements and the respective wall face urge the elements with a substantially constant force axially together into braking engagement with the disk. Seals between the brake elements and housing define a pressurizable chamber between the brake elements. The chamber can be pressurized to move the elements axially apart and out of braking engagement with the disk.
