Having problems with your Cars & Trucks ?

1988 crown victoria ltd new brakes seizing up

\015 Brakes were getting down and i was at the warning plates for about 2 weeks longer then i should have been. i replaced both front brake pads. i saw the rotors were too damaged so i replaced both of them as well. the calipers would not compress so i had to go buy a driver side caliper and when i got it all set up it still grinded a little bit when i spun the rotor. i was assured by my help thats normal. i got everything put together and the passenger side locked up badly on the test drive i took it all apart and it would not open up i had to buy another caliper for the passenger side. after putting it all back together for the 12th time my calipers still lock up and the brakes are making my tires drag. when the engine is off the lines get great pressure when i turn the key i lose it all. lines have been bled brake fluid has been checked emptied filled emptied filled bled filled. no leaks or broken lines. i cant figure out what it is and im already out about 200$ cant afford much more.\015 Posted / edited by AnonymousUser on : 17-09-2018

Where to start. . . .
A defective hose would only affect that wheel.
A faulty booster or master cylinder could cause the front wheels to lock and at varied amounts. You may have a metering block or just a junction block for the front lines. It would be mounted near the frame if you have one. Some Ford models from 88 - 92 used a master cylinder with the metering valve built in.
Its possible the front calipers got hot enough with the old pads to damage both front hoses.
I would want to know what it takes to release the pressure on the pads. Do you have to take the hoses loose, or just the bleeder screws on the calipers ? Or are the calipers not sliding back and forth ?
