brake problems

If a master cylinder goes bad, do you loose power steering and brakes? Where is it located in the motorhome? In or around a transmission?

No, if you have a gas rig then it's just like your car. They are entirely separate.

If your coach is gas you probably have hydroboost brakes, this system uses hydraulic pressure from the power steering pump to give "boost" to the brakes. So if your power steering pump goes bad you will loose the power assist to the brakes and also your power steering.

You mention a burning smell in your other post. I would suspect one of the hoses on the pump may have split and spewed fluid on the exhaust. If you are lucky you may only need a new hose and fluid refill.
