New original brake caliper too big?

[MyNameisChris]

Hello,

I changed my front brake pads and rotors on both sides and brake caliper on the left side today.
But now the wheel on the left wont fit. The new brake caliper, which is an original part and looks exactly like the old one, seems to be too big. I was able to put the wheel on, but it is completely impossible to drive. The caliper grinds on the wheel.
The wheels are original Subaru 15’’ alu wheels and I have the same problem with my 15’’ winter steelies.

The car is a 2002 Subaru Impreza Wagon, 125 hp.

Thanks for all help in advance!
