Disc brake system

Abstract

A multi-disc brake assembly has a hub that is rotatable about an axis with at least a pair of discs supported on the hub for relative axial movement along the hub. The discs present braking surfaces for a plurality of friction elements to move into and out of frictional braking engagement therewith. A non-rotatable support structure releasably supports at least one hanger member to slidably support the friction elements. Releasing at least one hanger member from the non-rotatable support structure provides for removal of at least one of the friction elements from the disc brake assembly while the inner caliper portion remains attached to the outer caliper portion. Additionally, at least two bores may be formed in the non-rotatable support structure in generally axially opposed relation to one another. Piston members are disposed in the piston bores for movement toward and away from one another causing frictional braking engagement with the braking surfaces.
