Drum brake

A drum brake has cylinders symmetrically fixed to a stationary member. Each cylinder has an axial bore therein with a groove for retention of a seal. A piston engages each seal to define chambers that receive pressurized fluid. Webs for friction members have a first end pined to an opposite cylinder...

description	A drum brake has cylinders symmetrically fixed to a stationary member. Each cylinder has an axial bore therein with a groove for retention of a seal. A piston engages each seal to define chambers that receive pressurized fluid. Webs for friction members have a first end pined to an opposite cylinder and a second end connected to an opposite piston and to each other by a strut. Pressurized fluid acts on the pistons to move the second ends with respect to the first ends and simultaneously bring the friction members into engagement with a drum to effect a brake application. The seals acts on and return the pistons to a rest position in an absence of pressurized fluid. A pawl on a lever is moved into engagement with the strut to bring the first and second friction members into engagement with the drum to manually effect a brake application.
