  • Truck Tips: How to mark and measure brake adjustment (video)
    Commercial drivers must ensure brakes are properly adjusted, with the mark-and-measure method being the most reliable for measuring brake stroke. This involves marking the pushrod, applying the brakes, and measuring the stroke to ensure it doesn’t exceed the chamber’s adjustment limit. Other methods, like measuring free stroke or using parking brakes, are less reliable and may give false readings. Mark-and-measure at full pressure is the best way to ensure proper adjustment.
