How do you replace front brake pads?

undo two bolts on back of calipers then lift off mine has four piston brembos fitted not sure if all 430 have them, then you knock two pins out holding pads take note how spring holding pads is positioned then pull sensor out of pad

I'm afraid to answer questions like this because if you can't figure this part out, will you be able to replace the brake pads safely? Get a repair manual and read up on the repair BEFORE tearing into a job you're unfamiliar with. Some of these MB's brake systems can seriously injure you if you don't know what you're doing!
