2. Proof that all the brake components, including the air compressor coerce girdle, are secure. They shouldn't be weakened, worn or damaged.
3. Verify that there is a compressor air filter and operative visible brake failure indicators when you essay air brakes.
4. Bad eye for slack adjusters that movement also far when brakes are applied.
5. Study the compressor hoses and Trimmings, drive belt and pulley for Exorbitant wear, cracks and tightness.
6. Corroboration the degree of air leakage by shutting down the engine with a fully-charged air action. Release the service brake and allow the air system to settle. Turn the engine off. Reduce the air pressure by depressing the brakes a few times.8. Confirm the service brakes are working properly.
Time the air pressure drops and record the loss rate. If that rate exceeds the recommended p.s.i. pounds per square inch), look for air leaks and repair them.7. Build up normal air pressure and depress the air supply knob.
