Has anyone else experienced this issue? I bought a full set of front and rear rotors and new brake pads from powerstop, they are drilled and slotted. The front rotors went on smoothly, however, when i tried to replace the rears, it seems like the new rotor is too thick and the brake caliper bracket wont fit over the rotor. Am i doing something wrong? Or does the rears have a different type of rotor and powerstop sent me the wrong ones?

Compare the thickness of the ​old worn rotor to the new ones. The difference should be small​​​​​​, only about 1.5 millimeter more for a new rotor. More than 2 millimeters could mean the wrong rotors. If okay, then make sure the rear caliper pistons are completely retracted.
Most C250s with gasoline engines have solid rear rotors. Other C Class cars may have ventilated rotors which will be too thick.
