There are three types of slack adjusters... what tool(s) you need to adjust them depend on the type you have. Either a 7/16" ratchet wrench or brake adjustment tool, a 9/16" ratchet wrench or brake adjustment tool, or that eight point brake adjustment tool (typically with a screwdriver, set of sidecutters, etc. to pull out the tab). You chock the wheels, release the brakes, adjust them all the way (so that the shoes press against the drums), then back them off 1/4 - 1/2 turn the opposite way. That's the 'in a nutshell' way. Done properly, you'd measure brake chamber stroke and adjust them to 1/4" under the legal stroke limit (what that is depends on what type of brake chamber you have on that axle). However, without actually being certified to adjust them, all you can do legally is depress the treadle (foot) valve fully to the floor to allow the automatic slack adjusters to adjust themselves. And, if you don't know what you're doing (because this question kinda tells me that you don't), that's really all you should be doing on your own.

What is the most commonly used brakes on an air brake system with drum brakes?
S-cam brakes.
How do s cam air brakes work on a school bus?
The brake chamber extends a rod out when the brakes are applied. This causes the S-cam to turn. The brake shoes are seated on the S-cam with rollers which roll along the countour of the S-cam as it rotates. When they reach a high point on the S-cam, they are pressed against the brake drums. This causes friction, which brings the vehicle to a stop.
Do you grease air brakes?
You don't grease the brake drums/rotors or shoes/pads, nor rollers. For s-cam foundation (drum) brakes, there should be grease zerks on the s-cam housing and slack adjuster.
What are brake chambers?
On an air brake system, the brake chamber is what actuates the air brakes... it converts air pressure to mechanical force, either turning an S-cam (on foundation brakes), or actuating a caliper (on disc brakes).
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.

What are s cam brakes?
the s cam you are refering to is part of the air brake system on tactor trailers. a relay valve sends air to each brake chamber or pot which moves a rod that has a clevis attached to it that goes to the slack adjuster which is splined to go on the end of an "S" cam. they are called S cams because the shape at the end is like an S.
