How adjust Volvo brakes with slack adjusters?
Volvos have automatic slack adjusters, which are dangerous to manually adjust. If your brakes are so far out of whack you think you might have to screw with the slack adjusters, you really need a brake job. Usually the slack adjuster must be backed off before you can remount the brake drums. The do have to be adjusted manually to get at least some drag on the drums before you set them automatically.
What are the slack adjuster?
slack adjusters are part of the brakes. they are ocated on the axle next to each wheel. they are used to adjust the brakes,or to take the slack out on the lickages so as the brakes do not have accesive travel when applied The slack adjuster is the link between the operating rod in the brake chamber and either the S-cam (if you have drum brakes, which is what most of us have) or the power screw (if you have disc brakes) on an air brake system. The "adjuster" part is because the friction material wears out, and you've got to make the linkage longer as it does so the truck will stop properly. (Slack adjusters have been automatic for a long time now.) In operation: you step on the brakes, or you pull the brake valves on the dashboard. The operating rod pushes out, which pushes the slack adjuster, which turns the S-cam, which pushes the brake shoes apart and stops your truck.

How do you test a slack adjuster?
Assuming we are talking about "S" cam air brakes on a truck, check the angle at the end of the slack adjuster to the actuator rod coming out of the air brake can when brakes are applied, it should be 90 degrees, if the slack adjuster is manual adjust it with the brakes not applied and then test again. If they are automatic slack adjusters and you do not have 90 degrees with brakes applied it is worn out or not installed correctly.
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.
