Slacker adjusters on an air brake system are what make it possible to adjust the clearance between the brake shoes and the brake drums. It connects the brake chamber pushrod to the foundation brake camshaft. these adjusters are located on the wheel axle next to the wheel. Unless you are operating an older type vehicle, slacker adjusters should have an automatic setting. If your vehicle is an older type, you will need to adjust the slackers manually. This is a two-person job, and should not be attempted alone.
