I agree with everyone that the brake job is pretty straightforward but let me share two pitfalls that I experienced.
1. While changing the rotors, one of the allen screws that hole the rotor became stripped. This added some time in drilling out the screw. To avoid this next time, I added anti-seize compound to the threads. If you run into a stubborn screw, I would suggest heat and or penetrating oil to loosen the screw (just don’t set the ML on fire)
2. After I finished the brakes would squeal terribly. I took them apart and sprayed an anti-squeal spray (Permatex make some) on the back of the pads. Sounds great now.

Good luck
