Brake Caliper Question
While driving, I am feeling what I believe to be the right rear brake engaging. The vibration and drag go away when I apply the brake to stop to investigate. I just changed the front brake pads and rotors. One piston on the right front caliper kept drifting back out after I compressed it. Can someone enlighten me as to how to address this problem?

Couple of questions first...
Did you bleed your lines when you changed the pads and if so, how?
Had you already changed the left side when you noticed the right side caliper kept drifting back?
How did you push the pistons back in? What was your process?

process
I changed the right side first. I pulled the wheel, removed the caliper, used a c-clamp with the old pad to press the pistons back into the caliper, installed new pads, tried to install the caliper but one piston had already extended, repressed with the c-clamp, tried again, piston had extendeded again, repressed with c-clamp, held the piston in with tongs, installed caliper. The left side went together as it should. I did not bleed the brakes, as the reservoir was never empty to allow air to enter. Something I failed to mention, it was the inside brake pad on the right front wheel that wore out (the one that the drifting piston pushes against), while the rest were still at 33% or better.
Thanks

I've got a similar situation where my right rear caliper will stick closed when i brake hard. Have hade smoke pouring off the caliper. Releases when I put the truck in reverse.
You might be able to buy a rebuild kit for the caliper but my advice would be to pick up a new caliper. They are around $100 up here in Canada.... FTE Parts Guy might be able to do even better

No but a bad master cylinder, clogged line or clogged portioning valve may.
I would suggest you do a full bleed first. Pushing fluid back in when you press the caliper piston back in is not really a good idea. In the future, it would be better for you to open the bleed valve and release the fluid out that way.
One man brake bleeders are readily available at most auto parts store to make the job a very simple one.
