Not sure if you guys have any input on this. Purchased nugeon calipers through rock auto and the rear right is slightly rubbing against the rotor. My other side has lots more clearance, is this some sort of issue with powder coating/paint throwing off dimensions?

Should I just use my old bracket with this rebuilt piston? My old bracket and brakes never had this issue.

Thanks in advance on any tips you might have.
 
Using non OEM calipers and or mount brackets (plates), can produce fitment issues. One being, OEM bleeders often do not seat in non OEM calipers. Remains brackets, may also have been in accident, which can bend mounting plate.

To be clear: Rub is at lower part on mounting plate, rubbing on rotor drum (hat)?
Did you clean the axle hub face, down to clean metal without removing any metal. So you could run out and so the rotor fits flush.
Did you runout axle hub face after cleaning. What was runout.
Did you run out the rotor, with 5 lugs on and torque to at least 20 ft-lbf., Then pull off and place back on, turn rotor to all 5 lugs position. Then turn rotor to best (lowest) runout. What was run final out.
You don't show the two bolts, with their thick washer, that secure mounting plate to rear axle assembly.
What torque did you use on mounting bolts and caliper pin bolts.
Are the pins fitment in the mounting plate sung. Is the one with rubber, in lower port.

BTW: You have the fitting kit in wrong:
Correct fitting kit orientation and gap between mounting bracket and rotor drum. I like my wear indicator on backside upper, since back pads always wear faster.

Hello thanks for the thorough reply.

Looks like the bracket is bent or the paint is causing fitment issues. Looks like I knackered up the top hat paint :(

I am able to fit the caliper by mixing the oem bracket with the old one. See photo.

FYI thanks for letting me know about the shim, I’ll flip it. (Wrong in photo attached)
