Driving home the other day I noticed a rubbing sound in the front end of the truck. It also felt like something was holding the truck back.
The next day driving home I started to hear what sounded like a caliper hanging up. Then the ABS light came on. I also have the shuttering brake pedal like the ABS was working under harsh condition like ice or something....
I got home and the passenger side wheel had lots of brake dust on it. So I pulled the wheel off, took off the caliper, had my wife push on the brake pedal and noticed only one of the pistons was working. I replaced the caliper-$55 later-still have the same problem.
Im thinking a sensor may be bad but Im still trying to figure out the rubbing noise and what is holding the truck back.
Any help would be greatly appreciated!

One last question, if ABS light is on, shouldnt my PHP Edge pull the code and tell me what/if any sensor is bad?

 

I got the same problem among others.. I tried changing out everything such as rotors , pads, front hub bearings, rear brakes I checked all my connections and I put in a new speed sensor .... So I am stuck as well .,. I was told to drive it until it gets worse and my wife says the truck needing repair is all in my head so this is where I am .. I am going to another Ford place in Canton , MS tommorrow to have a ABS code pulled by a rep..dealer.. Probably going to try and sale me a new truck like the other 2 did..

 

But my truck is hard to even drive. Almost like a CV froze or something. Or like the emergency is on holding back. Im trying to check the Ohms on the rear sensor. Im expected to see about 1200 if its good. So far, I have nothing but im also not sure i have a good ground. I hate cars!! Just a necessary evil!

 

Good news! Jacked up front end of truck grabbed the passenger wheel and it rocked side to side a good 3-4". I cant believe I didnt know it was going bad. Never heard or felt anything until 3 days ago. Anyway, I thought I would let you know in case you come across same issue.

 

Yep its the front hub bearing assembly.. I bought mine for about 140.00 at advanced auto.. Be careful not to bust an axle boot like I did when I changed mine out... The Jobs not hard ,, You need a torque wrench , 10mm 13mm 15mm sockets and my hub bearing nut was 35 mm it took me about 4 hours to do it

 

OH YEA Check your Cv axle as well they are only 60.00 at advanced and it would be a good time to cahnge it out if it needs it..
