1. 1. During a walk-around, a manually adjusted s-cam slack adjuster probably needs adjustment if it moves more than about how much?

   Correct answer: About one inch

   With the parking brakes released, pull hard on the slack adjuster; movement of more than roughly one inch where the push rod attaches signals it likely needs adjusting.

2. 2. What is the most common brake problem found during roadside inspections?

   Correct answer: Brakes that are out of adjustment

   Out-of-adjustment brakes turn up more than any other brake defect in roadside inspections, and too much slack can make a vehicle very hard to stop.
