![]() ![]() Some say if the slack adjuster is at no more than a 90-degree angle to the push rod when the spring brakes are applied, the adjustment is good. The problem is, how do you know that two brakes are adjusted well below the limit and three are over-stroking by an eighth of an inch? You cannot tell, but an inspector can. According to some a 2-psi per axle drop in system pressure, or 10-psi on a 5-axle unit, is acceptable. Slack adjuster full#You can release the spring brakes and build the system pressure to 100 psi, make a full pressure application and note the pressure drop. On disc brakes, it is between the pushrod and the power screw.On drum brakes, it’s between the pushrod and the S-cam.It is located on the axle housing on the air canister near the wheel. On an air-brake system, the slack adjuster is what is used to adjust the brakes.You cannot go by the mileage interval, like an oil change, you have to make the adjustment when it’s required. But since there are no such things as normal truck brakes, slack adjusters are designed to be adjusted. Slack adjuster manual#highway environment a manual slack adjuster would probably need adjustment approximately every 10,000 miles. It adjusts and takes up the slack in the stroke as the friction surfaces wear away. While there are some short-cut methods to determine brake adjustment but they will not be accurate enough to pass a DOT inspection. This means marking and measuring the brake stroke which is part of the trip inspection. When you sign the trip inspection form, you need to check the brakes to make sure they are in adjustment. However, all brake systems, whether manual or automatic slack adjusters, should receive regular maintenance checkups.
