Kudos to Mr.5 for a fantastic write up. Just did my rear pads (waiting for my fronts) on my '09 e93 and here are my two cent contribution:
I am a 62 years old fart and I did it in one hour 15 min, if I managed it you certainly can do it. I used simple tools: you need a 7 mm Allen 3/8 socket, small & big pliers, small hammer, flat head screw driver, 17 mm 1/2 inch socket for wheel lugs and a torque wrench. For supplies I used ordinary Centric posiQuiet semi metallic, synthetic high temp brake grease and non chlorinated brake cleaner, one can per wheel. Spray clean the calipers and the rubber of the piston prior to pushing in the piston. Open the fluid reservoir. Use light hammer to gently tap the spring back into the slot of the floating caliper. Did not and do not recommend taking the carrier part out of wheel hub unless you are also replacing rotor. Look carefully for the shiny worn parts of the old pads, and only dab those points of contact with the high temp synt brake grease on the new pads. DO NOT USE any gluey stuff such as CRC or Permatex. German floating calipers are not designed for that, note that the oem pads are NOT COATED with that gluey gunk. NEVER use any anti-seize compounds on the threads of high tensile bolts (bmw oem bolts are rated high tensile strength), otherwise you will induce "creeping" and premature failure of the bolt will occur. Be careful to lubricate the shafts of the shear pins only, but not the thread part. Looks like the shear pins threads were coated with LocTite. Watch out for the brake sensor (passenger side) it got a tiny small metal clip that can get twisted or snapped off. Otherwise just follow the instructions as posted by Mr.5. I only removed the shear pins of the floating calipers not the 16mm high tensile bolts of the carrier part. The Centric posiQuiet pads are so smooth compared to the OEM pads, now my bimmer glides to a velvety stop. No squeaks at all. You must immediately "bed in" the new pads. Have fun.
Sou fanático por conversíveis...
