Rear brake lock up??

Never seen this before. I have a 71 C10 LWB originally came with manual brakes I got a power brake set up from a 72 C20 LWB. Was working great for the last two weeks, then all of the sudden I started breaking today and my rear axle locked up when I braked I let off and it released?? At first I thought my proportional valve went bad. I popped the master cylinder cap and fluid poured out the front chamber in the master cylinder. It was overfull and the rear one was about 1/2 low. I took a little fluid out of the front part and put the cap back on and its not locking up any more. Any one every have this happen or experience with this?? Know of any possible broblems or is this common?
