I usually find my answers by searching but i couldn't this time. Sorry for the long read but i wanna give you guys all the background info to make it easier to find a solution. I have a '90 SC with a brake problem. Initaially it was a hard pedal so the car was parked for about 3years with that being the only problem with the brakes.
I recently did the conventional swap with the '90 tbird booster, 93 crown vic master with proportioning valve, and the longer pushrod. All parts purchased from autozone. Took it around the block the car had a real low pedal but the brakes dragged! so i adjusted the rod until i had the feel right but the brakes still dragged.
So i bought all 4 remanufactured calipers from autozone swapped them thinking it would fix the problem but it didnt, all 4 still drag and i know this because they start to smoke. Now i know you cant always trust a new part in a box to work but all 4 being bad is hard to believe so i think its something else. I also exchanged the booster at autozone since it was new still no luck, and i picked up a master at a local junkyard that didn't fix it either.
I did some research on this forum on how to fix the abs, ran the tests and came to the conclusion it was the accumulator ball, I ended up putting the ABS back in with the new ball and the hard pedal is gone the brakes feel great but they still drag. I checked the lines and found no pinches, and the hoses don't look bad no cracks or anything. When the car was parked I had the Front calipers off the car for more than a year so air was in the lines all that time, could that have ruined my hoses and lines from the inside? Any suggestions will be appreciated.
By the way if anyone is interested i have a new '90 Cardone booster with the long pushrod, New '93 Crown Vic BENDIX Master, crown vic proportioning valve, and a '90 Used tbird master from my swap that im selling since im gonna stick with the ABS.
