Vehicles that pass inspection receive an official DOT Sticker and inspection form.

Defects identified during inspections are noted and repair estimates are presented to vehicle owners. No repairs are made without owner approval. Vehicles that pass inspection receive a copy of the official inspection forms.


Empire is your one-stop shop for troubleshooting and repair services for commercial truck air, hydraulic and anti-lock brake systems from all makes and models. Our large inventory of in-stock brake parts keeps repair time to a minimum: most jobs are in and out in a day.


Clutches have never required much preventive maintenance, and those in newer vehicles need even less. Empire's standard practice for heavy duty clutches follows the specifications of the Technology and Maintenance Council (TMC), which lists four primary factors affecting heavy duty clutch service:

  • Powertrain specifications (engine, clutch, transmission, axle and tires)
  • Control of powertrain torsional activity
  • Driver technique (starting gear selection, engagement technique, driving habits)
  • Clutch maintenance (adjustment, lubrication, protection from rust and contamination)

"These factors are not independent of each other" says TMC. "For example, powertrain specifications can have a major effect on the third listed factor - driver technique."

Dyno Service

At our Empire Truck & Trailer Phoenix, AZ location, we use a chassis dyno to check your engine’s performance, help you get maximum fuel economy and troubleshoot any hard-to-diagnose engine problems. We can also check your cooling system to be sure it’s running at peak efficiency — that’s important in the desert!

Electrical Systems

Empire technicians are experienced in the inspection and repair of all electrical systems. Wiring shorts are often found to be the source of electrical failures. High-tech computer systems allow us to detect and repair them quickly.


Empire technicians have been trained and equipped with the specialized skills and experience needed to troubleshoot and repair commercial truck air and air ride/spring combination suspensions. In addition, we are able to perform front-end repairs on all makes and models, maximizing your vehicle’s safety, tire life and fuel economy.
