Answer
Cristian, pretty straight forward, BMW brakes are easy. Buy a Chilton, Haynes, or Bentley manual for your car if you are going to be doing service. I recommend only BMW pads, rotors, and sensor. They may not last as long and are a little more expensive then aftermarket components, but they stop so much better than the Hard long life brake pads if is not even funny. And with brakes safety is the name of the game. Remove the brake spring, pry the caliper back a little to get the pads/caliper to clear the rotor. Two 7mm allen bolts behind the black covering caps. Two 16mm regular anchor bolts for the mounting anchor. Clean the channels on the mounting anchors where the ears of the pads slide with a wire brush. Remove the Rotor anchor bolt 5mm allen and beat the rotor loose. Wire brush off the hub and lightly grease it with high temp grease. Depress the caliper piston back in it's bore (I use large tonque and groove pliers). Lightly grease the brake pad backing where the caliper touches the metal backing (Antisieze, NAPA's Silglide, BMW grease 81 22 9 407 103 <small packet>). and reassemble all parts. Wear sensor goes on inner pad with hump toward the rotor. Brake lining light will go out if you turn the key on engine off. Let it sit. Pump brake pedal until hard and check brake fluid level.
