Abstract

The quick-release mechanism is for spring-accumulator type brakes, particularly as used on motor vehicles, having a piston moving a thrust plate and against which the spring acts on one side and compressed air on the other. The piston (9) has a neck portion protruding into the spring chamber (7), and a seal between it and an axially-sliding guide spindle (15). The spindle passes through a seal in the spring chamber end, the thrust plate (19) being fixed to its protruding end. A pin passes through the spindle in the radial direction, its ends fitting in recesses in a sliding washer, guiding the latter and bearing positively against the piston base.
