Why is it essential to follow manufacturer specifications when adjusting slack adjusters?

Following manufacturer specifications when adjusting slack adjusters is vital to maintain optimal brake performance and safety. Slack adjusters play a critical role in the braking system by controlling the distance between the brake shoes and drums. If not adjusted according to the manufacturer's guidelines, the brakes may not engage or release properly, leading to decreased stopping power or uneven wear. This can significantly increase the risk of brake failure, compromise vehicle safety, and endanger both the driver and others on the road. Proper adjustment also ensures that the braking system operates efficiently, which is essential for the reliable performance of the vehicle.
