These brakes require special adjustment to the manufacturer’s specifications.

ALL BRAKES

At the first stop after adjusting the brakes, check each brake drum or rotor for temperature. An extra hot brake drum indicates that you have adjusted it too tightly.

Only when all brakes are properly adjusted will the system be able to absorb the required amount of energy to bring the loaded vehicle to a safe stop under extreme conditions. Remember that poorly adjusted air brakes may appear to be working at slow speeds on light air application. THE ONLY WAY TO BE SURE THAT YOUR VEHICLE BRAKES ARE PROPERLY ADJUSTED IS TO PHYSICALLY CHECK EACH WHEEL.
