About 4 Series Brakes

Great gods, I want to ask if I need to change the oil pump to change the front six pistons and rear four pistons of the Brembo (the original car has a single piston front and rear)?

I would suggest to get the 2NH brake booster if you are upgrading from sliding calipers to fixed-pistons.

The electric parking brake would be eliminated with the addition of multi-piston rear calipers.

Not necessarily the EPB system will be eliminated if the OP is planning to do this:
