I use OEM regardless who the source is.
All suppliers must meet the M/B spec on brake components.
I change the front pads at 35,000 mile intravals and the rotors every other pad change.
The rear pads go twice the distance as the front.
STOMP STEER STAY that's ABS technique.

Edit: I Change the brake fluid every spring as the owner's manual notes.
