So I finally got time to work on my Juicy rear brake. See thread here. Got the pads out, cleaned everything with 95% ethyl alcohol. CAREFULLY squeezed the handle so the calipers came out just a little. Cleaned some more.

Got everything put back together. Spun wheel -- no rubbing on the disk. Squeeze lever -- Some (very little) pressure. Wheel stops. Everything stops. No pressure in lever; brakes are not letting go.

WTH? no oil leaked out. Which means all the oil is in there someplace?

Ok, more research. Looks like I seriously screwed up. I pushed on the center of the piston to open it back up. This is a no-no?

I don't have a bunch of tools. Am I getting in over my head?

go to the "Juicy Overhaul section"

"Use a 11mm box wrench to push caliper back in". Yes you should avoid pushing the locating pin in the center of the caliper.

Just sounds like the caliper(s) are seized. Remove the brake pads and push them both all the way in (and I mean all the way, not just half way) Then press the lever to get them back out. You might have to repeat this a few times.

It might help to apply a bit of brake fluid with a q-tip to lube them to help them go in and out.

When you push the pistons out, it takes several squeezes of the brake lever to make the pads contact the rotor again.

Thanks for the info. I won't get a chance to work on them again until the weekend. I have to decide if now is the time to keep trying to work on these or wait until summer (take to shop for now). Biggest issue is the difficulty in doing this outside in the cold. Just in case oil goes "spllttt!" Time is second.

Again, thanks for the info. I am learning. And I WILL get to where I can do this on my own. Appreciate everything. Will keep you updated.
