About one month ago, Rear brake hoses were replaced and brakes were bled. At that time the shop told me the fluid drained was pretty 'nasty looking'. Now the pedal sinks to the floor and I am basically unable/unwilling to drive/stop the coach.

When I tried to press the little button on the combo valve, it did not seem to move at all (which makes me wonder how well the brakes were bled).

A few days of Googling and I now suspect the master cylinder may be at fault (I believe it is the original)..but possibly the combo valve.

I have ordered both a master cylinder and combo valve from one of our GMC suppliers. Any advice on how to determine the root cause...or do I just replace them both??
