Ok I have a 1985 chevy K5 blazer, lifted with larger tires. I just got new calipers on both sides and new top gasket for the master cylinder. My problem is my two front brakes are not locking up completely but they are biting down on the rotor more than they should. I put the front end up on stands tires off the ground. Tried to roll the tires and it was very difficult. I removed the top cover and it sounded like there was a good bit of pressure built up in there it made an escaping gas noise (like opening coke). I bled the brakes again then tried to move the tire and it moved really easily so I thought my problem was solved. Took it on a test drive and started to notice the smell of brakes. Pulled in garage jacked up the front and again the tires are difficult to move. Anyone know what is going on?
