Ok, I got past the rusted on rotors by using the method desribed here:

But since I put my old pads back on and did that stop & go method, my caliper on the left side has become stuck in the outward position. My C-clamp is getting me nowhere. I even tried attaching a wrench to the end to give me move leverage. All that did was start to bend the handle on the C-clamp. I've sprayed it pretty liberally with some penetrating oil...

Any suggestions?

Come on, where's the help at around here? Somebody has to have the answer to this...

 

Are you talking about the piston?

Or the caliper itself on the slides?

 

Oops. The piston. It is what is stuck.

 

Replace the rear calipers.

 

It's possible the piston came out too far, and it's crooked in there, and hung up.

If so, it's also probably no good at this point.

Your going to have to pull the rubber seal, and check to see if it's got the piston messed up, before you go any further.

I would use several clamps spaced around the piston to see if it will go back in, after checking it for damage.

Good luck.

 

I would mirror what he said, but would also add a "Why Bother?" at the end.

Personally, I'd just replace the caliper. They're relatively inexpensive, readily available, and most of them come with a warranty. .

just a sug.- i may be wrong since i am not familiar with the workings of the f150 brakes. but- i had much this same problem on a car that i did a brake job on once. i too tore up a c-clamp trying to push the piston back in. depending on how the emergency/parking brakes work on these trucks- you may have to turn the piston back in. there is a special tool to do this- but i always use a screw driver. look at the face of the piston- does it have an "X" or a couple small holes cast in it? if so- the piston needs to be turned back in- almost like it has really large threads.

like i said- i am not familiar with the f150 brakes yet- but it's just something you might check. i know i felt like a complete tard after a friend clued me in on what i was doing wrong.

 

Not on the F-150s and Expeditions. They use a completely independent set of parking brake shoes that ride inside a small drum in the center of the rotor.

Good to keep in mind when working on GM products though...
