Changed the front end rotors and pads on my F150 Saturday. Drove it Sunday no issue but driving home yesterday afternoon the brake light came on. When I got home I noticed a smell coming from them and when I spit on the rotors it bubbled. Drivers side ABS sensor is toast when old rotor went out and pushed into it. Stuck caliper or something else?

Not enough grease on the pads possibly? If you don't put enough when you change the pads, this would definitely happen.

calipers sticking, need to replace them or you will be doing another brake job really soon.

You're putting grease on the inside aren't you?

How many miles on the truck? What year?

Sometimes caliper pistons can stick. Did you clean and lubricate the caliper slide pins? Sil-Glyde is the best lubricant. Do not use anti seize.

On older F150's I have had the front lines swell and plug up over time and make the calipers drag.

Its a weight distribution issue. You've got too much weight on the front wheels. You forgot to re-install the nuts on your rear bumper didn't you?

Depending on the year, there is a recall on F150 brakes. Not that exact problem, but it's free if the year is right.

I had the exact same thing happen on my f150. Turned out my buddy helping me put the pads on wrong. He put the exterior pad on the interior side(vice versa). I swapped them around and was good after.

Possibly the wrong type of break pads used. Did you switch to ceramic?

this will always happen. Always.

confused by this, was this before or after repair.

Do you have a surface temp reading, or is it a guesstimate that it's hotter?

what is a stuck caliper? You mean the piston engages and then doesn't ease up when there is no hydraulic pressure against it?

Some brakes are tricky and if the pins aren't' on right the pads can have too much friction. A sticking piston is possible though.
How did you push the piston back in? Was it flush and level? I have seen people put the piston back in in a slight angle and it caused the piston to get stuck in the caliper.
You could rebuild the caliper with a new piston kit, but much easier just to swap, but now you have to bleed your brakes.

F150 has a ceramic piston that cracks/breaks causing the pads to remain in contact with the rotor.

Not too uncommon when new brakes are bedding in. Depending on the style of brakes I'd say no grease on back side of pads, or on slide pins. Highly doubtful that you would all of the sudden stick calipers.

mother f'er. I hope the E150 doesn't have that. I helped a friend change his odd-ball spark plugs in his F150, one broke. Such a pain to change. Why'd they change things that worked so well before?
