You might want to do one at a time when you adjust your breaks do the trailer or truck first while leaving the breaks applied to which ever your aren't adjusting as chock blocks are easily run over if your on any kind of incline!

The ONLY time you should adjust and Automatic Slack Adjuster is on initial installation and in emergency situations where you need to get the unit to a repair facility immediately. It is DANGEROUS to repeatedly adjust an automatic slack adjuster. Just read the instruction manual on ALL brake adjusters and it clearly states that.If an automatic slack adjuster fails to hold the brake stroke within the adjustment limit, there is either something wrong with the adjuster or the foundation brakes are wore out.

I can't take a video seriously where you think tapping on the brake drum is part of the procedure... it is as simple as turn them all the way on, then back it off 1/4-1/2 turn. You can even turn the wheel for a slight drag if you want.

What if your deaf
-
just tighten them all the way in and back them up a 1/4 turn

when i took my roadtest for a Class A1, i had to perform adjusting a manual slack adjuster, this one looks wrong
-
wrong procedure.

good video! Never thought of going by sound. I'm working for this new company and one of the vehicles is a 98 Mack Dump truck! I'm adjusting amongst every brake every day! the slack adjusters come way out! what would cause them to do that daily??

How come you use a 7/16" wrench?My truck brakes use a 9/16" wrench. Been that way forever, I thought...

Why did you make this video?
-
Fail .

This is not how to do it lol
-
Truck driver smart like dump truck.

I'd like to hear the reasoning behind adjusting BEFORE measuring stroke. And for God sakes you have the book, read it, it says do not adjust auto slacks! Your job is simple. YOUR JOB is to measure applied stroke. Don't even think about grabbing a wrench. If its out spec, its likely a foundation brake issue, so find a shop. It is YOUR JOB to be responsible and safe. A fully loaded truck is no joke and "sorry" ain't gonna undead those people.

I wonder in the end of the video, if he noticed that he had an applied air leak?

I'm looking for certification like so tht my co. Will allow me TO ADJUST my brakes you think 45yrs of trucking I'd be allowed all I need is certificate any input would be greatly appreciated

If you need to adjust automatic slack adjusters you have a failed brake component or brake foundation issues (failed means a component that no longer works as it should, can be lack of maintenance or wear and tear). The only time your brakes should need to be adjusted are after wheel, brake or hub assembly service.
