Brake Repair


Medium and heavy-duty trucks use highly engineered parts to come to a complete and safe stop. Unlike the brakes on a car, commercial brakes can be responsible for slowing upwards of 80,000 lbs of truck and trailer load. No matter what type of fleet you manage, it's critical that the brake system works properly to reduce the risk of accidents. At Sun Valley Diesel & Auto, we work with drum and air disc brakes. Our qualified technicians can inspect the condition of your brake system and install replacement parts when it's time.

How Often Do Brakes Need to be Checked?

Brake service intervals differ between fleets and depend on several factors, most notably:

  • Service environment
  • Frequency of use
  • Brake part quality

The fleet and diesel truck technicians at Sun Valley Diesel & Auto can inspect the condition of your brakes, diagnose the cause of problems like decreased stopping power, and provide the proper brake repair.

Steering & Suspension Repair

Suspension Repair in Prescott Valley, AZ

When you need suspension work performed on your heavy-duty trucks and fleet vehicles, contact Sun Valley Diesel & Auto. Problems with the suspension system cause added stress on other parts of the truck, including the tires. Depending on the problem, your truck may require a wheel alignment, new shocks or struts, or replacement of other suspension components like the tie rods and ball joints.

The suspension system is responsible for absorbing shock from the surface of the road to create a comfortable ride. Over time and due to wear, suspension parts weaken and require replacement or repair.

The service staff at Sun Valley Diesel & Auto can assist with all your fleet suspension work needs. We service ball joints, hub assemblies, shocks and struts, sway bars, and other suspension parts.
