Brake problem can't seem to fix.......
Well i've had a problem with my brakes randomly will start to go on as i'm driving down the highway. it's not all the time sometimes it will be fine and won't even do it for the entire day and other days like this morning it was doing it for 15 minutes out of my 1 hour drive. it would seem to help if i slammed the gas on hard they would stop dragging.. I've been to lots of mechics and two ford dealers and no one can tell me exactly what is causes the problem. i've pulled the fuse for the ABS just cause i've heard that can cause problems and that didn't work.. the one ford dealer i was at today said they have only heard of this problem once before on a 2004 superduty and they replaced every caliper, rubber brake hoses, master cylinder, hydroboost and it still would do it sometimes. so i'm totally lost on what i should do. i've replaced calipers on my truck flushed out the brake lines. flushing the brake lines seemed to help a bit but still didn't fix it. anyone heard of a powersteering pump that works fine cause this? that was the only thing they didn't replace on that 04 that had this problem other then that the truck had an entire new brake system on it....

My best guess is your caliper slide pins are hanging up. The caliper itself could be bad as well. Ive had to replace 2 calipers on my 06 because of intermittent random dragging. The first time i brought it to ford they couldn't find the problem but after the rotor got so hot the second time they spotted it.

I read a thread on here a couple of months ago where several people said the brake hoses were worn on the inside and causing brakes to drag, one guy had a situation similar to yours where he did all that work and still had the problem, turned out to be the hoses.

I have also heard of problems when you flush out the brake lines, or do any other work to cause a back pressure, or air into the system and it can find its way into the abs module. The only way to bleed the brakes properly would be with a scanner that has the option of opening up the abs, to flush out the whole system.

I've taken the calipers off and greased the slide pins a few times and replaced two calipers already this summer. it's not the pins it's all four brakes go on at the same time not just one brake....

Yea i've heard of that and so did the ford dealer i was at, but we both agreed that there is no way all four hoses would go at the same time to cause all four brakes to stick..

If the pedal is hard to push, it may be your vaccum pump, the pump on my '05 failed twice in 40,000 miles.
