In a braking apparatus, a buffering member that is formed using a flexible material is disposed between a fixed portion and a movable portion. An accommodating recess portion that accommodates and holds the buffering member is disposed on a buffering member holding portion that includes at least one of the fixed portion and the movable portion. An opening portion that communicates with an external portion of the buffering member holding portion is disposed on a portion of a side surface of the accommodating recess portion. The buffering member is removable from and insertable into the accommodating recess portion through the opening portion from a direction that is perpendicular to a direction of displacement of the movable portion.

A brake drum for a vehicle braking system includes a closed end, an open end opposite the closed end, a braking wall axially extending between the open end and the closed end, and a compression device that applies a radial compressive force to the braking wall thereby increasing the thermo-mechanical fatigue resistance of the braking wall. A first restraining tab on the braking wall to axially restrain the compression device on the braking wall.

A brake camshaft and a method of manufacture. The brake camshaft may include a tube portion, a cam portion, and an end portion. The tube portion may have a first tube end, a second tube end, and a tube cavity that extends from the first tube end to the second tube end. The cam portion may be disposed on the first tube end. The end portion may be disposed on the second tube end.

An integrated brake component mounting bracket for a mechanical spring axle/suspension system of a heavy-duty vehicle includes an axle seat that is disposed on and is rigidly connected to an axle of the vehicle. An air chamber mounting bracket is rigidly connected to the axle seat, and a cam shaft assembly mounting bracket is rigidly connected to the axle seat. A brake air chamber of a brake system is attached to the air chamber mounting bracket, and a cam shaft assembly of the brake system is mounted to the cam shaft assembly mounting bracket. The integrated brake component mounting bracket thus provides mounting of the brake air chamber and the cam shaft assembly on the axle seat, which reduces the number of components that are welded to the axle and enables the use of a thinner-wall axle, desirably reducing the weight and cost associated with the axle/suspension system.
