Vehicle & Equipment · Driver Training VideoAir Brakes & Brake Adjustment
A loaded rig at 55 mph needs about 450 feet to stop, and air brakes add lag. Drivers learn the daily gauge numbers, the 2-inch pushrod limit on a type 30 chamber, and why 20 percent defective brakes puts a truck out of service.
Branded with your logo & company nameWhat drivers learn
Your truck does not stop with brakes. It stops with air, and air takes time. A loaded rig at 55 miles an hour needs roughly 450 feet of dry pavement to stop, and about 30 of those feet happen after your foot is already down. That is brake lag.
Start with the numbers you check every morning. The governor cuts out between 120 and 140 psi and cuts back in near 100. Build up rate: 85 to 100 psi in 45 seconds. Static leak, engine off and brakes released: no more than 2 psi a minute on a single vehicle, 3 on a combination.
Now adjustment
Your brakes are only as good as your pushrod stroke. On a standard type 30 chamber the readjustment limit is 2 inches. On a long stroke type 30 it is 2 and a half.
Almost every truck on the road today has automatic slack adjusters. Understand what that means. If an automatic slack adjuster is out of adjustment, cranking on it is not a repair.
Heat is the other enemy
Brakes fade when the drums cook. Pick your gear before the grade, let the engine brake carry the load, and snub: steady pressure until you drop about 5 miles an hour, then release and let them cool. Repeat.
Your company standard: the full air brake check, every pre trip, out loud, in order. Any brake past the stroke limit, any leak rate over the number, any warning device that comes on late, and the truck does not roll until it is fixed.
Air is free
Brakes are cheap. What is behind you is not.
