What you get: prevention plan
Worked out by this tool from its default inputs. Its role plan lets you run your own numbers, print the sheet and save it.
Brakes: check every pre-trip, and stroke measured at every pm; your out-of-service orders cost about $4,050.00 a year
- Out of service when
- 20% or more of the vehicle's service brakes are defective or out of adjustment, or a steering-axle brake is inoperative.
- Check at pre-trip
- Pushrod stroke, air leaks (loss rate), low-air warning, slack adjusters, linings.
- Common mistake
- Assuming automatic slack adjusters never need checking; they mask other faults.
Prevention plan: brakes
- Puts out of service
- The vehicle
- What to check
- Pushrod stroke on every chamber, air loss rate, low-air warning, linings and hoses

The plain-words read of this example
Brakes puts the vehicle out of service under the CVSA criteria; prevent it by checking pushrod stroke on every chamber, air loss rate, low-air warning, linings and hoses, every pre-trip, and stroke measured at every pm. Over 24 months your 20 inspections gave a vehicle out-of-service rate of 20.0% and a driver rate of 5.0%. At $1,620.00 an order, that is about $4,050.00 a year, $405.00 per truck. After an order, the repair is certified on the inspection report and returned to the agency within 15 days. Keep a corrective-action log for every order and feed the cause back into the pre-trip.
