The brake, including a brake housing, is characterized by a housing having an inwardly extending flange forming a pressure chamber with an annular piston slidably positioned in the brake housing, and the annular piston and a secondary piston are operatively associated with opposed sides of the inwardly extending flange to form pressure chambers therewith for individual actions in the brake. Spring means operatively engage the secondary piston for moving the same into operative pressure braking position for fail safe braking operation. Air pressure is sup...
In a wheel braking apparatus including a drive axle, an axle housing, a wheel journalled on said housing, and a brake housing characterized by an annular piston slidaBly positioned in said brake housing and forming a first pressure cylinder with said housing, said wheel having a tubular hub extending into said brake housing and being concentric to a tubular portion thereof, a stack of brake discs alternately keyed to said brake housing and to said hub by spline means, a second piston operatively carried by said annular piston for limited axial movement t...
