Brake caliper sticking
So changed brake pads front passenger, found caliper weeping so bought a new one. Damn pistons wouldnt retract enough to get new pads on. Finally went on. Bled caliper. New caliper sticks. Brake caliper is engaged no matter what. Swapped caliper. New one isn’t so stuck, however you can hear the grinding when ever so slightly and when you brake sure enough pulls hard to the right. What am I doing wrong? Oh yes after the second caliper I bled the entire system with new fluid.

Possibility your brake hose needs replacing. They break down inside and when the brakes are applied and released, they don't let the pressure go back through the system and lock up the caliper. I had this happen to the rears and really toasted my rotors. Good luck.

Something like this made or bought ( i had some sheet metal and bent) or 2 crossed screwdrivers....
you may also crack the bleeder when pushing back if needed then re bleed..
do one side at a time..there are springs in pistons they are supposed to push out..but not lock..
push them back evenly so as to not catch sides of pistons

oh and in future do one pad at a time starting with inner and don't do both at once. i should have known better. see number 6 where my dirty fingernail is pointing (i've been working on the vette so i have the right to be dirty lol)

So I found the metal shim behind the pad itself jammed between the dust cover and rotor making a grinding noise. I must have forced it in so hard and didn't notice it fall off? I don't see how. Anyway I changed them again. pulled hard to the right. I talked to a friend of mine and he said to wear them in. I would hard brake going very slowly around the block then drove for a bit and it went away 95%. The alignment is horrible so dropped it off today for that. Lastly I should have done both fronts but since I ran into this didn't want to destroy both. Will change on friday and see how it goes plus alignment today will check out

Mike, if you only did one side of the front, without at least changing the pads on the other side at the same time, you are going to get a certain amount of pulling to one side or the other. At the very least try using the below Brake pad & Rotor Bed-in Procedure to see if that helps.
"Bedding-in new pads and rotors should be done carefully and slowly...Most brake pad compounds will take up to 300-400 miles to fully develop an even transfer film on the rotors."
Good luck... GUSTO
