the brake still operates like it should, the piston isn't seized like I thought, I can turn the axle and push down the pedal and it grabs, but when the pedal is all the way up, the pads still bite and drag

yeah than i would pull the pads off and pump the brake to see if you can push the piston out. do you have pressure? when u get the piston out look at the plastic seal, make sure its good. and use a dremel with a wire wheel to clean up the inside of caliper. i put a little bit of water resistant grease in mine after i cleaned it up

the axle turned freely before i installed the caliper, i checked those bearings thoroughly when everything was apart. but i will be pulling it apart to check this stuff out in the caliper itself. the piston doesn't seem to move

yeah bad axle bearings will cause it to turn hard in a spot or two during the rotation. my old ones did this and my brother in laws honda 250 did the same, calipers were fine but bearings were not.

I would say you got a bent rotor, or a stuck caliper. And your sure it's the brakes not the axle bearings.

Even if the piston is sticking it's easy to pull them out and clean the inside of the caliper with a Dremel wire wheel and re install them. The slides may be stuck also. To pull the piston out you have to take pass out and pump the brake lever and it should basically fall out. You probably knew some of that info but just throwing it out there.

ok I will give this a try, I hope the piston isn't seized  [|]

You can also remove the caliper and pull the pads, they might have stuff in/behind them.

Or if you put new pads on you might need to push the piston back out like you do on a car.  If you do this make sure the piston is not hung up on anything.

Make sure the axle is square to the swing arm, or the brake could drag a bit.

Hey guys I'm in the middle of my rebuild and my rear caliper is really tight on the rotor and I can barely make the axle turn, is there a way to back it off a bit when there is no pressure being applied to the brake or is there something I'm missing here?
