Don't to forget the brake hoses going to the front cylinders. My front left was locking up. Night and day difference!!!!

Thanks jeff. It is a 2003 F150. Guess I should replace all the brake hose.

They are like in the $30 ea. Range. I couldn't beleave how swollen shut the line was. The Expedition has 220k on it. So it is the same as a Ford F150 I think. Huge pads and rotors. If you come to a trafic lite and when you let off the brake pedal and they moan a little and then the truck starts rolling.....you have swollen lines.

That's usually caused by contaminated brake fluid. Somebody cleaning the lines and not flushing the cleaner out. Somebody adding oil to the brake fluid reservoir. Something like that. In humid areas, just leaving the cap loose so humid air contacts the fluid will do it!

Naw it's just a age thing for those rubber lines, it was a common problem for 90's Chevy's, we replaced them on the wife's 98 GMC, sons 94 Chevy pickup and daughter's 96 Monte Carlo, all had around 100,000 miles when the hoses needed replaced. They had just been replaced on the wife's 01 Chevy pickup when we traded for it, I replaced the ones on the 95 F-350 I had at 170,000, we replaced the brakes on my 04 F-450 last year, wasn't having any issues but with 115,000 miles we decided to changed the lines while it was apart.

On those 90's Chevys it was common to get a build up of mud or ice on top of the metal bracket that holds the brake hose to the spindle.
Hit a few real good bumps and the upper control arm and mud will bend the metal bracket and crush shut the flex hose.
This will give all the symptoms of a collapsed hose.
Two minutes with a flat blade screwdriver to bend back the bracket has got me home more than once.
