Air Brake System Repair
When commercial trucks require air brake system repair, the causes and solutions can be relatively straightforward. Things such as improper alignment, condensation, and faulty air compressors are common reasons why heavy-duty vehicles need their brakes fixed. A mobile diesel mechanic can usually fix the air brakes in place. But if the damage is too extensive, we can bring the big rig into our repair facility for expedited service.
Drive Line Service
When a truck’s drive line begins to falter, the power transferred from the engine to those 18 wheels can become unpredictable. Given the weight of a fully loaded tractor-trailer ranges up to 80,000 pounds, it’s imperative to have a certified diesel repair specialist identify the problem and take corrective measures. Parts such as U-joints can often be replaced at the scene. We can also tow the rig to our state-of-the-art automotive facility and prioritize your drive line service repairs if necessary.
