M543A2

I had the hard pedal problem with my dump truck. I found that bleeding air out of the air pack bleeder at the top of the air/hydraulic valve on it solved the problem. The air pack has two bleeders, one at the end of the brake cylinder and one at the top, on the air/hydraulic valve. Check them both while you are under it. We have a bridge truck here for farm use. No other truck like it!.
Regards Marti
