Ive got an 04 f150, and its about to piss me off! Ive been havin brake issues for a while now but it comes and goes. at first the drive side front started draggin and heatin up, then it moved to the passenger, back and forth then to the rear passenger. I cant remember if the drivers rear has done it or not but it keeps movin. about half way home tonight from work I could tell it felt sluggish and didnt wanna go then it got to were I could smell it. got it home and now its both front and back passenger side locked up. any ideas what is causing this? I could understand a caliper stickin but not that many at one time or the problem "moving around" I plan on tearing into it monday and checkin all the calipers and might as well change pads while im at it, but im not sure of the main problem and id hate to eat up a new set of pads for nothin

I would try looking at the calipers. And possibly new ones.
I had the same thing happen on my f250. some how, im guessing previous owner mistreated it, and the caliper cylinders were busted.
Also, brake pads could be too big for the calipers.
Had a buddy had a f150 and took it to have brakes put on when he was out of town, they smashed f250 superduty brake bads in there and caused all kinds of problems..
NOt a mechanic, but just some of my thoughts...

Sounds like something in the lines. He said it was swapping sides, pressure "should" be even once it leaves the master cylinder?

I would atleast remove the master cylinder, drain it, and blow it out and check to see if there is anything floating that may be getting pushed into the lines and stopping them up
as not having enough fluid and filling full of air can cause them to be soft and continuous use can lock up the brakes up,
calipers may be bad now, but hard to say. brakes as well and since the locked up, you may have to get the rotors turned or replaced,

also look at the cap on the master cylinder, I know on my dodge there is a gasket make of some type rubber that keeps the air from getting in and as well as keep the fluid in, is possible this has gone bad, rotted, torn or whatever and allowing air into the cylinder then into the brake lines
