danny :

buses and alot of others have the same system but the manufactor suggest caulking wheels wheels so they dont roll

Expert:  danny replied 6 years ago.
The parking brake cable has failed Most likley it wil fail again on an incline. and will fail easier as time goes by. I would diffenatly have a set of caulks to put under wheels on a incline. I would contact the manufactor of the truck and see if there is a recal or tech service bulletin on it.

expert says chock the wheels unacceptable same question asked differently .would a 7 ton truck parked on a incline with an automatic transmission and no park position and only a pull hand brake that had been repaired 4 months earlier. The owner had no chock We had put approximately 1000 lbs.on the truck in the course of an hour when the truck started rolling. a tree xtopped it and the parking brake was still engaged. Is it engineered safeley, no park position no air brake just a simple hand brake!
