An adjustable brake system for a railroad truck wheel frame. The system includes an elongated body secured to a railroad truck and rotatably secured to a plurality of wheels, the elongated body having a brake side pocket positioned near a wheel of the plurality of wheels; a compression bar and an extension bar extending from a first side of the elongated body to a second side of the elongated body; a strut positioned between the compression bar and the extension bar; a brake head rigidly secured to the compression bar; a protrusion extending from the brake head and configured to engage within the brake side pocket; and a cam rotatably attached to the compression bar and configured to engage within the brake side pocket.

A truck mounted braking system is provided with a mechanical pivot adjustment on the bake lever connected to the brake cylinder push rod to permit the braking force applied to the wheels to vary depending on the lading condition of the car, without involving additional pneumatic elements such as a pneumatic empty load device. The brake cylinder may be provided with a channel which permits the push rod to achieve different positions based on different positions of the brake cylinder push rod.

A corrective device for correcting uneven brake shoe wear on a brake mechanism for a railway vehicle, wherein the railway vehicle includes a brake beam having a tension beam coupled to a compression beam, a brake head with brake shoes provided at each end of the brake beams, and a slack adjuster. The corrective device is configured to cooperate with at least one of the compression beam and the slack adjuster to minimize or prevent the compression beam and the tension beam from rotating relative to the wheels and side frames of the railway vehicle. A braking system including the corrective device and a method for correcting uneven brake shoe wear on a brake mechanism for a railway vehicle is also provided.
