97 F-150 brakes sticking

1997 FORD F-150

I have a 1997 Ford F-150, 4.6l, 4x4 with 133,000 miles. The front brakes have started sticking and they get very hot until the drag makes me stop. After they cool, it is again drivable. When the truck starts to shimmy, I know it’s starting. I’ve changed the master cylinder, cleaned the reservoir and put in new fluid and bled the lines. Any ideas?

Check the calipers, could be binding up, also check the rotors, when they get to hot the tend to warp, creating as shimmy.

I have a 2001 Ford F-150, 5, 4l, 4x4 with 90,000 miles. This vehicle has long travel front and rear and is used primarily offroad. Recently I've had the same problem. The front brakes stuck on me 2 hours from my house. I could get them unstuck by cracking the bleeder screws at the calipers. However, once the brakes were applied again while driving and the heat built up the same thing would happen. I replaced the calipers, pads and fluid. Same problem occurred. Today I replaced the master cylinder. I am having problems bleeding the brakes now. I didn't bench bleed the master cylinder. I think I still have air trapped in the system. Did you prime or bench bleed your master cylinder? Also, the push rod coming out of the brake booster behind master cylinder had resistance when puting on MC did yours? I read that could be out of adjustment causing brakes to drag. The only other thing I have not replaced are the hoses coming off the calipers. Mine are extended steel braided 4 the long travel a-arms and would be $120 bucks. I will let you know what I find out, please do the same if you determine the problem.
