The reason I did the master cylinder was because of the hard pedal. After rebuilding the MC, running some new brake lines and bleeding the system with my 13 year old Son, this has been a great learning expirence. Probably the MC was OK and was the wheel cylinders all along. I watched a guy on youtube last night change out the wheel cylinders, so thats our next lesson to rebuild them. Right after I check wheel 2,3 & 4.
