So, I switched out the master cylinder in my 96 disco Tuesday. When I pulled out of the driveway, to take a trip around the block to check out my work, everything seemed fine. I was proud. Well I was making the trek back to Richmond, about a 2 1/2 hour trip, I heard a sound coming from my front passenger wheel well. It sounded almost as if the caliper was engaging. After a few miles of this I noticed a sensation, almost as if someone was tugging on my disco, no jolting but like I was towing something. Then the brake pedal suddenly froze, I mean I couldn't budge the thing, and my engine started overheating. I pulled over and popped the hood for a quick check fluid levels and what have you. And suddenly I heard what seemed to be pressure being released from, where I'm not sure, maybe the abs box. So I hopped in turned on the ride and the brake pedal went to the floor. So I decided after spending a month with a faulty master cylinder, and pumping my brakes to stop, I could do this. I took off and eventually pressure built and I made it home. Right before I got home though, It went through the same process, noise from the wheel well, stiff brakes, to unmovable pedal, and an overheating engine. Does anyone have any ideas what the heck could be going on with my brakes? I'm completely confused.

 

And it happened again today on my way to work. I took the abs fuze out hoping it was that, but no dice..........

 

And if I crack the lines going to the master cylinder, or the bleeding valves, the brake releases

 

could air in the lines or a bad booster be the culprit?
