With the Brake Sentry visual brake stroke indicator, a driver can visually inspect and identify unsafe, out-of-adjustment conditions. The industry-recommended “applied stroke” inspection procedure can eliminate the need for mechanics to mark and measure applied stroke at each brake chamber. This also eliminates unnecessary and damaging manual adjustments to automatic slack adjusters; identifies hard-to-detect problems; and reduces driver reports, road calls, downtime, fines, and out-of-service violations.
