An adjustable brake system for a railroad truck wheel frame, the system comprising:
- 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 non-adjustable protrusion extending from the brake head and configured to engage within the brake side pocket, the non-adjustable protrusion being rigidly attached to the compression bar, and the non-adjustable protrusion is configured to fit within the brake side pocket;
- an adjustable adapter rigidly secured to the compression bar, the adjustable adapter being positioned on a surface opposing the brake head, the adjustable adapted having an elongated key and a bore;
- and
- an adjustable cam secured within the bore of the adjustable adapter and configured to extend into the brake side pocket, the adjustable cam is configured to engage with the elongated key;
- wherein the non-adjustable protrusion and the cam both fit within the brake side pocket;
- wherein the cam is configured to rotate within the brake side pocket to a desired angle, which in turn causes a surface of the adjustable cam to engage with the brake side pocket;
- and
- wherein the adjustable cam and the non adjustable protrusion engage with interior surfaces of the brake side pocket to hold the brake head in a desired position.
