Did you know …….. The two major defect areas resulting in a CMV being placed out of service are Brake System Defects and Out of Adjustment Air Brakes! In a matter of a few minutes a driver can easily adjust air brakes equipped with manual slack adjusters and check for other brake-related defects. Many drivers are trained to adjust brakes but some choose not to or are not certified to.
The main objective of Brake Safety Week is to “Reduce the number of highway crashes caused by faulty braking systems on commercial vehicles by conducting roadside inspections and educating drivers, mechanics and others on the importance of proper brake inspection, maintenance and operation.”
Drivers may also want to familiarize themselves with CVSA’s Operation Air Brake Inspection Procedure so they know what to expect if they are stopped for an inspection in conjunction with Brake Safety Week. The inspection, outlined below, will focus on the following inspection items:
Driver’s License
Registration
Low Air Warning Device
Pushrod Travel (Adjustment)
Brake Linings/Drums
Air Loss Rate (If leak detected)
Tractor Protection System
