Help, I changed my rear tire and went through all the steps by the book. had a little trouble getting the brake caliper on but it finally went. After all was done, I went to set the brake pads and the pedal would not move. It is locked up. tried forcing it and managed to lock up the breaks. Had to oped bleed line to release the pads. Any ideas as to what happened. Took caliper off to check and saw nothing wrong. Pedal still locked up. Need advice.

maybe too much fluid in there.  If you had topped off the master and then compressed the pistons.....well bad stuff can happen

When you were having a hard time getting the caliper back on, that was a sign that you needed to compress the pistons back into the caliper a bit. Try removing the caliper again, compressing the pistons a bit, and trying again.   Use a clamp, make sure to have a pad in on the piston side to clamp against, and remove the top of the master cylinder to monitor the fluid level. Since you need to do all that, I would push the cylinders MOST of the way out to clean all the gunk and contamination from them before compressing them back in.

The pistons should go back into the bores easily. It sounds to me as though somehow the wheel was installed incorrectly.

You could have crap in the brake line that pushed back into the master cylinder when you reinstalled the caliper.

First thing to do is locate where the problem is!

A brake bleed would eliminate the master cylinder from the mix.

Proceed as necessary.
