Hello everyone. I have been having a huge problem with the brakes on my '98 GT. It started off with me having to replace the rubber brake hose on the front passenger caliper due to a cut in the line. I replaced both front brake line hoses and cleaned up the calipers and pads. I do not have ABS on the car so I bled the brakes as usual and everything worked fine for a bit. However, soon after I was driving when the front brakes grab essentially locking up the front wheels. I have to wait for the car to completely cool before they release in order to drive again.

This now happens EVERY time I drive the car and I can't get more than 4-5 miles before the front calipers seize up. I have completed exhaustive research on the issue and have nearly replaced or rebuilt the entire brake system after having this problem for more than 2 years now. Listed below is everything I have done in order to solve the problem but to no avail:

Replaced front rubber brake lines to calipers
Replaced all four wheel brake pads
Rebuilt front calipers
Replaced rear calipers
Replaced master cylinder
Replaced proportioning valve
Replaced hydraulic power brake booster

Is there ANYONE that has any ideas? I have hit a wall and don't know what to do anymore! Please help!

Replace the front calipers.

The front calipers would be the only part that would cause the drag, what did you rebuild on them? Just buy new ones and your problem will go away.

Exactly. It's more cost effective to just buy new ones

I appreciate the input. Well it is now official...I have replaced the entire brake system with the exception of the metal brake lines. Replaced the front two calipers and am still having the problem. So any other ideas?

Your riding the brake ???

I'm stumped, every time I've dealt with dragging brakes, it's been from worn calipers not releasing completely.

Kind of a long shot, but sometimes the slider pins on the back of the caliper bracket get frozen and have to be lubricated

Actually I am the opposite of a brake rider...I prefer to downshift and use the brakes as little as possible. Somebody suggested to check my hub and bearing assembly. If one or both of them need servicing or replacement it causes the brakes to drag. The more they drag the hotter the calipers become which eventually causes the brake fluid to overheat and increase the pressure to the brakes. I am going to check them today and will let you know.
