Provided air makes its street into your brake limit, your brakes could lose their effectiveness and develop into hazardous. The crowing habit to grip your vehicle protected and avoid an accident is to countdown the air brake development regularly.


1. Look all Accoutrement when testing air brakes, including drums and discs, hoses and chambers, slack adjusters and actuators, relay valves, tanks, pipes and Trimmings.

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.

Attain normal air pressure and discharge the parking brake. Move forward at about 5 mph and firmly depress the brake pedal. Check the brakes if your vehicle pulls to either side, have a strange feel or a slow stopping action.
