What Is the Most Common Cause of Air Brake Failure?

The most common cause of air brake failure in heavy-duty diesel vehicles is air leakage, often from worn hoses, faulty valves, or loose fittings. This reduces air pressure, preventing proper brake function. Poor maintenance and moisture in the system can also contribute to failure.

How Do I Know If My Brake Drums Need Replacing?

Brake drums in heavy-duty diesel vehicles need replacing if you notice deep scoring, cracks, excessive wear, vibration during braking, or reduced stopping power. Regular inspections revealing measurements beyond manufacturer specifications also indicate the need for replacement to maintain safe braking performance.
