This bus runs good does need some preventive maintenance that was neglected. My question is that my skoolie have the brakes with calipers and a flip down emergency brake And it seems as if the master cylinder has a motor built into it on bottom. As soon as I turn key on it is humming very loud and never stops unless un plugged. Also it's like my back drive brake is dragging enough that a 15 mile trip it heated up enough to start smoking and smells like I locked the brakes up. No visible sign of leaks. Any advice is appreciated.
