We all know the importance of having good brakes on any vehicle or trailer. Whether it be a car, utility trailer, or semi-truck and trailer, it is so important in the trucking world that the CVSA (The Commercial Vehicle Safety Alliance) dedicates 1 week every year for certified inspectors to focus on random brake checks. Safety should always be a top priority for truckers, and a malfunctioning brake system can lead to severe accidents, so keeping your brake system in top condition is crucial.
Brake Safety Inspection Check-List
- Check the gladhand washers. Ensure these are in good shape and sealed properly with the power unit.
- Inspect the service brake valve and ABS system. These components are crucial for your braking system to function correctly.
- Look for loose parts. Make sure that there are no loose or missing parts, especially around the air tanks.
- Check for leaks: Is the petcock-drain valve leaking? Are there any airline leaks or cracks? Also, watch out for chafing between the airlines, which can lead to holes.
- Measure your slack adjusters. Use your pre-trip tool to measure the slack adjusters. They should be no more than 2 inches on a standard-stroke brake chamber or 2.5 inches on a long-stroke brake chamber.
- Inspect brake shoes and linings. Check the percentage of wear on your brake shoes and linings. If they’re below 30%, it’s time to consider replacement. Any thickness below .25 inches is below the DOT legal specs.
- Examine brake drums and hubs. Look for excessive wear grooves in the drums, which can reduce braking power.
