Inspection第 25 / 60 题
During a walk-around inspection, how do you check manual slack adjusters on S-cam brakes?
a.By listening for air leaks at the wheel
b.By measuring the air pressure at each chamber
c.By pulling hard on each one and checking that it moves no more than about one inch
d.By spinning the wheel by hand
解析
With the parking brakes released and wheels chocked, pull hard on each manual slack adjuster you can reach. If it moves more than about one inch from where the pushrod attaches, it is probably out of adjustment. Brakes that are out of adjustment do not work properly and are unsafe.
