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. |
Although it does indeed appear that the piston is sticking as well.
I did earlier give a method of diagnosing a sticky piston, but for the rear
brakes you need to cut the number of pedal presses to 2 or 3, NOT eight.
The rear pistons eject a _LOT_ farther than the front ones do!

side. They actually are much closer in thickness than it first
appeared, I looked at the boot on the caliper piston, and there
was junk on the inside edge of the seal that has been sitting for a
while, so, I'm pretty sold on the caliper being sticky for a while
now... At the rate these pads wore out I'm thinking it must have
been March or April that the caliper started to go as the rear pads
before were definitely worn heavier on the left than on the right as
well. So, I'm going to order a new caliper tonight. I'll be
checking back in once it arrives for some insight on installation...
Looks straight forward, one bolt for the lines, and slip off the
clip for the e-brake. Just have to get some help with the bleeding of
the lines. Maybe this is a good time to replace the fluid? I'll
have to read up on how to do that.
thanks again

I went back to the pads and compared again, holding them side by side. They actually are much closer in thickness than it first appeared, I looked at the boot on the caliper piston, and there was junk on the inside edge of the seal that has been sitting for a while, so, I'm pretty sold on the caliper being sticky for a while now...

That's pretty much it. It's best if you get a couple of new copper washers
for the hydraulic fitting.

You MUST do a thorough bleed, as anything less will leave air in the new
caliper and you'll have a soft pedal.
That caliper is really complex inside, with many nooks and crannies that
trap air bubbles. Get a nylon mallet while you're at the parts place;
you'll need it.
