Automatic slack adjusters

Pretty much same, same here in AB. The air brake course can be included in the Class 1 instruction or taken seperately (as I did).

When the driver's license requires renewal, usually every five years.

 

apparently i have oddball auto-adjusters, then. I am told that mine adjust when full pressure is applied (obviously not at highway speed), and I only need a flat screwdriver and a cresent to manually adjust them. I was only taught this after I found part of the adjuster missing during my pretrip, which in turn resulted in a complete brake job on that axle because of the leaking seals. Yes, I do my pretrips right, they just didn't leak enough to see without taking the drum off.
