Air Brake System Repair
Our team will inspect and make any necessary repairs to your air brake system. Included in the air brake system is compressor servicing as well as servicing and repairs of governors, dyers, fittings, lines, valves, hoses, chambers, and ABS systems. We leave no stone unturned during our inspection process.
Here are some of the steps we will go through during your repair.
MONITOR YOUR MINIMUM OPERATING PRESSURE
The minimum operating pressure for an air brake system is no less than 100 PSI for a truck, and no less than 85 PSI for a bus.
We will monitor the time that it takes for the air pressure to rise from 85 PSI to 100 PSI at 600-900 rpm. This should take no longer than 2 minutes in order to pass inspection.
CUT-OUT GOVERNOR PRESSURE
Road Runner will ensure that the correct cut-out governor pressure for the air compressor is between 120-135 PSI. They will then go on to ensure that the cut-in pressure is 20-25 PSI below cut-out pressure.

Differential Repair by Certified Mobile Truck Repair Specialists
If you hear a noise coming from your differential, this can be a sign of insufficient lubrication. It could also mean that the gears and bearings have been worn out due to wear and tear. The Road Runner team can give you a full assessment and determine the best course of action.
While most of our truck repairs can be done wherever you are located, this particular repair would need to be done in-house at Road Runner’s repair shop. Problems with your differential can be extremely costly, let’s fix it before it gets to that point! Give us a call today at 703-450-7555 to set up an appointment!
Exhaust Repair Service
Most large cities subject vehicles to emissions testing. Failure to pass this emissions test will lead to you having to repair or completely replace your exhaust system. Our Mobile Truck Repair team will ensure that your vehicle will pass its emissions test!
Aside from the emissions test, a properly functioning exhaust system significantly improves your truck’s functionality. Your truck’s exhaust system is more complicated than you would expect. It involves exhaust manifolds, cylinder heads, oxygen sensors, catalytic converters, and mufflers. Failure of any of these components can result in a harmful impact on your gas mileage and environmental impact.
Our Mobile Truck Repair team can also help with exhaust brakes. The exhaust brake system will use the exhaust gas pressure to aid with vehicle braking. This system helps to ease the demands on your wheel brakes and therefore increase their total lifespan.
Radiator Service by Mobile Diesel Mechanics
Anyone who’s made a career on the road knows how frustrating overheating problems with diesel engines can be. Our Mobile Diesel Mechanics have seen it all, trust us! Diagnosing the cause of engine overheating takes skills and experience. Here are some issues that our mechanics will keep an eye out for:
The mobile diesel mechanics will first check your truck’s coolant level as this can often be an indication of a crack in the head gasket or the engine. Another cause is not as easy to see to the naked eye, air pockets. Air pockets in your system can cause a serious restriction of fluid flow and alter your coolant levels significantly.
Something as simple to clean as a build-up of deposits on the injector nozzle can cause the fuel injectors to malfunction. Your truck’s engine will need to work harder to compensate for the malfunctioning diesel fuel injectors which in turn will lead to overheating.
Our Mobile Truck Repair teams are professionally certified and will be able to quickly identify the underlying cause of a malfunctioning cooling fan. Be it a misaligned fan, a defective coolant sensor, or engine thermostat issues, our team will find it and have it repaired quickly.
Our mechanics will keep an eye out for a faulty water pump issue. If they notice a pulley spinning faster than it should be, this is indicative that the water pump seals are wearing out. Clogs in the system can also cause water pump issues and lead to overheating.
Suspension and Steering Repair Services
- Suspension Air Bags
The Road Runner Mobile Diesel Services team can repair suspension air bags. This will prevent swaying and leave you with a much smoother ride! We will analyze the suspension height sensors in order to properly calibrate them and have the proper air pressure settings for the flow between the compressor to the airbag.
- Leveling Valves
We will inspect and repair any air suspension level control rods, front axle leveling, right side level valves, and left side level valves.
- Leveling Linkage
The Mobile Diesel Repair team will ensure that your truck maintains the proper ride
height by inspecting and repairing or replacing your leveling linkage.
- Air Lines
We will thoroughly inspect the air lines supplying the air bags. Any signs of wear and tear will be addressed and reinforced. Should a replacement be the safest route, we will take care of that for you quickly and efficiently. Our mobile repair mechanics are qualified to work with lines from all brands, including Milton and Continental.
