The wear is teeny tiny, just enough so the caliper tends to float to

let you know quickly.

Long shot, but if you wheel where it's muddy, dirt can build up behind the pad
and it won't retract properly, the heat then cooks the mud solid. Usually the
brake shield and tire rim keeps debris out.

I pulled the caliper today and the piston was frozen, I culdn't move it back
in at all. Also, the anti-squeal shim on the fixed side pad had pulled loose
from the pad backing plate and was slightly distorted.
The fluid is new, however I found some small metal particles in the drain
pan I put under it. I flushed a buch of fluid through the the line into a
glass container and didn't find anything in it, so I assume the crud came
out of the old caliper. Despite the fact that the paads were twidce as worn
on the right side as the left, the rotors are identical thickness..weird,
musta been pretty soft pads.
Anyway, on went the new caliper from NAPA and a fres set of pads on both
sides.
The axles have been on there for over 20k miles and the pads on the drivers
side were virtually identical thicjness to the ones out of the box. Amazing
how litle work 3/4 ton brakes do ano a 1/4 tone vehicle. ;-)
Drove it a lot today to bed in the new pads and everything seems fine. Just
seems odd to me the thing semi-siezed like that. Never seen anything like it
before.

If the piston was plastic, get ready for the other side to swell
and jam too.

Re: Dragging front brakes. $#@!
It appeared to be metal, as did the piston on the new one.
Now, next questioon for GM experts: The old pads had a retailing spring clip
that holds the piston side pads to the piston. There weren't any new ones in
the box with the new pads, so I transferred the old ones. The clips push the
pads ever so slightly past the edge of the rotor and I'm wondering if that
clip is unnecessary. Stopped by my local Jeep / GMC dealer
yesterday and they found that the factory had discontinued the clip as a
replacement part. Hmmmm, maybe I shoulda tossed the clips, wadddya think?
