Re: CAT 777D Truck

Truck will not move as it needs oil pressure to release the park brake. Needs to be running.

CAT 777D Truck

Please answer me a question on a 777D trucks brakes (Im not on site so cant jump on the machine and do the test).

 

 If a 777D truck is parked on a incline with the engine not running but the air tanks are full would the truck roll if the park brake was released? Or must the engine be running?

            Thanks in anticipation,
