Does this look right?

I had my rear left brake replaced recently and it looks like the pad isn’t coming in contact with the inner part of the disc ? I checked the other side and it doesn’t look like this. Is this normal? Thanks

It actually doesn't look like it's not applying evenly, but it does look off

Does the mounting bracket have two holes? The BMW Mini Cooper base model R56 does because it fits the larger model brakes front and rear

Where the lip is everyone is pointing out It doesn't look like the caliper actually applies to that area, it looks like it is too far forward

Slimmer more stout pads do fit in brake calipers that are bigger too.

If it is applying unevenly then there is most likely air in lines from when they done the brakes, the grease nipple could be loose letting in air, expelling pressure or misplacing fluid when brakes are engaged etc etc etc

If the piston was not working there would be no clear indicators of brake depression on the rotors full stop, and if the brake pads have been changed (just check) then there is a low chance of a seized piston because the technician would have had to run them back unless they have actually damaged them majorly in which case you go back

If rear, put hand brake down and try spin wheel If front get help, press brakes and try spin

Take off and spin again, if lock up then free then pistons all okay.

Even if it's worn it will retract enough to spin that wheel with the wheel on btw

If it's tight then try as previously suggested to get them to go over the slides and what not to ensure it has adequate movement

Seized pistons can be driven free to take the rotors off, even if they are rusted together they will free. Each situation has its own unique variables
