When should a vehicle be rejected based on brake shoe travel?

A vehicle should be rejected based on brake shoe travel when it exceeds 1/16 inch because this measurement indicates insufficient clearance or excessive wear in the brake system. Brake shoes are a critical component for effective braking performance, and having too much travel can suggest that the shoes are not properly adjusting, which may lead to compromised braking efficacy. Insufficient brake performance can pose serious safety risks, especially if the vehicle is unable to stop effectively.

Braking systems are designed to provide a quick and responsive stopping power, and any deviation from specified measurements must be taken seriously. Therefore, maintaining proper brake shoe travel ensures the overall safety and functionality of the vehicle on the road.
