I have a 92cougar that I recently replaced the front roters and pads, shortly thereafter the front brakes locked up. I replaced the master cylinder,( in the process the front brakes disengaged), I followed all manufactuers instructions, as soon as I started to move the car they locked up again, I bled all the lines and this did not help,there is no ABS system on this car. Somebody please give me a good solution to my problem. brain

 

You likely have bad rubber flex hoses going to your calipers. Throw them out, replace them and rebleed your system. Failing that, stuck calipers.
