hey all, this past summer ( early august maybe) I replaced the pads on the rear of my 03 accord. the left side was worn badly, the right, not so much, but I did them both with OEM pads, this week my wife said the brakes were squeeling, and sure enough, the rear left was making noise. looking at the outer pad on the left side there is 1/2 of the material worn off, compared to the right side already, maybe 7,000 miles into the new pads... I haven't had a chance to take the wheel of and look at the inner pad, but, I'm starting to think that that rear is dragging constantly, so, what can I do to fix this? is a new caliper in my future or ??? thanks for the thoughts and ideas.

Not likely a bad caliper, but a sticky pin or pad.

obviously...
hey, I watched that vid of you turning in the piston on the caliper
on the rears, I remember when I had to do that back in the summer it
took WAAAY more force for me, I ended up putting the screwdriver
lengh twise to the groove and used the shaft of the screwdriver in the
groove of the piston to turn it... ( did that make sense?) I tried to
turn it with the screwdriver normally, but that did not work at all...
the other side did turn a fair bit easier...
I know the pins looked decent at the time, and I could pull them free
with my fingers.
based on all that info I'm thinking that that the piston is a bit
sticky, If I remember right, the inside pad was much more worn than
the outside pad this summer, and I'm guessing the same has happened
again...

under the shims.. I know I had to pry off the the old pads with a
screwdriver and they popped out of place pretty smartly after getting
a bigger screwdriver... I gave lip service to cleaning under the
shims with a screwdriver, and was able to place the new pads in by
hand, but, it wasn't loose.
I live in SE Michigan, on a dirt road where they put calcium chloride
down in the summers... can't think of many worse places for steel
brake parts to live...

pins not moving freely. Did you disassemble and re-grease them, then
put them back together right, or did you just test that they moved,
then leave them be?
The rears (especially) need the full service done each time. They get
a lot of crap from the road splashed on them.

and needs to be taken off. Then, make sure you lube up all of the
contact points.

If the inside and outside wear at different rates, it points to the pins not moving freely. Did you disassemble and re-grease them, then put them back together right, or did you just test that they moved, then leave them be? |
them at every oil change. I forget which side wore faster, but I presume
it had to do with a single piston, essentially pushing one pad against the
disc which then had the added burden of moving the caliper before the other
pad touched.

Or one pad being clamped much more than the other on account of rust.

The primary problem with the rears is that they never get very hot, so
moisture doesn't boil off them. This means they rust like crazy.
I can't quite remember how hot the fronts got last time I checked, but the
rears only get up to about 90-100F max. I think the fronts get up to about
140-160F under normal use.

K, so I got a night to look at the wheel in question its the rear left.. rear right is in perfect fine shape... The inside pad on the rear left is down to the squeely (whatever you call it "wear indicator" ) the outside pad is at least twice as thick as the inside, though probably only half the thickness of the outside pad on the rear right ( and yes, they were replaced at the same time... ) |
Then you still have a sticky pin or outer pad. No way around this, my
friend.
What the piston itself is doing isn't important in the context of that
inner pad.
