Hey Guys,


I was looking to find a DIY guide to replacing the front and rear brakes and rotors on my 2012 E350, most everything I could find out there only outlined changing the front pads. I was hoping to find something detailed as this will be my first attempt on any DIY project for my car. I appreciate any help you can offer, thanks!

See attachments.

Perfect timing for this thread! Just got my parts today and tackling front and rear this weekend.

Going to flush the brake fluid with fresh Pentosin as well. Cheers.

Good info from Konigstiger; be aware, however, there is a caveat about self-locking bolts used to mount the calipers. If the bolts removed are micro-encapsulated bolts, one should run a tap through the mounting threads to clear out any remaining encapsulating material. This also implies one should purchase new bolts. The M12 caliper bolts run about $4 each at the dealer with discount. An M12x1.5 tap should run about $7 on Amazon Prime. (Verify the threads on the new bolts first.)

From the torque values, these are Grade 10.9 bolts. The bolts will most like require a 1/2" drive wrench and extension. Be aware that when the caliper bolts break loose, they do so quite suddenly.

FWIW, the front M14 caliper bolts on my W211 E55 are torqued to 180 Nm (132 ft-lbs!).

Are these these the 4 bolts provided with the OEM front pads from Mercedes?

would be even nicer if someone could provide a DIY on brake bleeding process , that be great actually

Not to my knowledge. The part numbers are separate for brake pads and the brake hardware.

Did a search on youtube....came up with this.
