Test Your Brakes

Test Your Brakes 

Faulty, leaking, or inoperative brakes can cause you to receive a violation or even worse. Test your Automatic Brake System (AB) by firmly pressing on the brakes. Pumping the brakes tests the ABS by verifying the system's ability to maintain proper air pressure, detecting potential air leaks through sound cues, and confirming the brakes engage and release promptly, indicating functional ABS operation.  

Orange & Black Has Your Back! Here’s when and how to check your brakes. 

When to Pump the Brakes: 

  1. Pre-Trip Inspection: Before starting a run, it's required for truck drivers to test their brakes during the pre-trip inspection. All truck drivers should get into a routine for pre-trip inspections. 

  1. During Long Trips: Periodically checking the brakes during long trips can help detect any potential issues early, especially before any weigh stations. 

  1. Before Descending Steep Grades: Testing the brakes before starting a descent ensures they are in working order. 

How to Pump the Brakes for Testing: 

  1. Park the Truck: Ensure the truck is on a flat, stable surface and park it securely. 

  1. Build Up Air Pressure: Start the engine and let it run until the air pressure reaches the correct operating range, usually 100-125 psi. 

  1. Apply and Release: Apply the brakes firmly and then release them. Do this several times to ensure the air pressure builds back up and the brakes respond correctly. 

  1. Check for Leaks: Listen for any unusual sounds that could indicate air leaks in the system. 

  1. Monitor Gauges: Keep an eye on the air pressure gauges to ensure they return to the normal range after each application. 

Testing your brakes regularly by pumping ensures that the truck's braking system is reliable, reducing the risk of brake failure and enhancing overall safety on the road. Roadrunner offers fuel and maintenance discounts. If you’re ready to Run with Roadrunner, apply today.
