Abstract
A method to inspect and compensate for wear on a brake shoe of a railcar brake system includes removing the railcar brake shoe from a brake head of the railcar brake system, placing a brake inspection device between the brake head and a railcar wheel, applying brake load, measuring a gap formed between the brake head and the wheel, measuring the thickness of a stop block of the brake inspection device positioned between the brake head and the railcar wheel, determining an adjustment distance as the difference between the gap measurement and the thickness of the stop block, and adjusting an end extension of the railcar brake system in accordance to the determined adjustment distance.
