I have a bmw 435i coupe M sport package that came with just the gray color front brembos (4 pistons I believe so), but the rear ones are just like regular calipers.

Does anyone know if the Brembo rear brake calipers (to be used with a 345mm rear disc) are compatible with my car?

These originally came from an f80/82. Please, see the attached pic of the actual rear brembos that I would like to install on my car.

Also, pardon my ignorance at this, but when is time to replace the brakes, Do the shop change/replace only the break pads from my brembos, or the complete kit?

I greatly appreciate your help with this matter.

Thanks!!!
