Is it legal to replace automatic slack adjusters with manual slack adjusters?
Where I live if the truck was manufactured with automatic slack adjusters you can NOT replace them with manual ones. Check with your local DOT you never know.
If a trailer with automatic slack adjusters can they be changed to manual slack adjusters. Legally?
Why? ASA's are an improvement over manuals, and eliminates periodic adjustments. Legally, if it came with ASA, you must keep them on and maintain them. Read your CMV book, if you are in this business, you better know it inside and out.
How many slack adjusters are on a semi truck and trailer?
Two per axle.
What is the difference between manual and automatic slack adjusters?
The difference between manual and automatic slack adjusters is the way in which the brakes are adjusted. Automatic slack adjusters have sensors that do not let the brakes get too loose or too tight. Manual slack adjusters have to be adjusted by hand and can be set too tight in some cases.
Is it legal to replace manual slack adjusters with automatic slack adjusters and do both sides of axle have to be replaced?
Looking through FMCSR 393.47, the only requirement I see in there is that the effective length of a slack adjuster on each end of an axle must be the same.
Slack adjuster parts on rail road cars?
Yes there are slack adjusters on railroad cars. They work much like the automatic slack adjusters on large trucks, and do the same job
How many trucks do have automatic slack adjusters?
43
Does an 18 wheeler have 18 skack adjusters?
No. You'll have two slack adjusters per axle, assuming it's using s-cam foundation brakes all around - disc brakes don't have slack adjusters.
How do you check the slack adjusters condition in commercial vehicle?
that's easy if the slacks are working they will adjust the brakes .if they are not working the brakes will be out of adjustment. I work at a class 8 truck dealership, there are 2 types of slack adjusters, auto and manual. If you have auto slack adjusters, they will adjust themselves to a point, however, if you have no braking capability to speak of other parts are probally wore out, s cams or clevis posibbly s cam bushings, brake chambers. Manual slack adjusters should be checked in my opinion only at least at every pm or when braking capability suffers. Those big trucks take a lot more time and space to stop and their brakes had better be in good shape or dot will shut them down if caught.
What is the acceptable travel for the slack adjusters?
half inch or less
What factors can cause your brakes to fail or fade in a semi?

How do you adjust the slack adjusters on a 2007 freight liner columnia?
Without ASE certification to service and adjust air brakes, the only adjustments you are legally allowed to make are the ones which the automatic slack adjusters make themselves - you may not adjust brake chamber pushrod stroke. To actuate the automatic slack adjusters, all you have to do is press hard on the brake pedal a couple times - the slacks will adjust themselves. As far as making manual adjustments in order to adjust stroke travel, again, it's illegal to do without proper certification, and it is the policy of Wikianswers not to permit answers to questions which pertain to illegal acts. Furthermore, this is not something you'd want to try doing without some training - if you don't get it right, this is something which can have disastrous consequences.
