thanks,




When I took my W212 to dealer for sensor coding, without asking they presented me with $5200 estimate for recommended jobs, what include $720 for new pads. I measured the pads to have 6mm, or over 60% of meat on them.
To be honest, I can't vouch for the Brembo rotors just yet, since they haven't been on the car for that long ( around 4k miles) and I'll have to look into them shuddering again. I recently went on a longer trip (2k miles) to the east coast and I think the shudder might be back ( either that or the roads, usually freeway exit ramps, were so uneven that the steering wheel would shake visibly when lightly braking between 60-35mph). I'll report back after more research and tests. At least I have a 2 year warranty on the rotors and pads, which is nice

All i can say its amazing.....no visible brake dust.
It screams only from cold start, after that its super quiet on the road.
But i m not sure what rotors i am on, probably stock.
Front Brembo rotors and pads are not a suitable replacement for the W212 E550 since they start shaking again after awhile, in my case it was around 4k miles. We had to drive today and I could definitely feel and see the steering wheel shake under light braking, the worst feeling would be around 40 to 30 mph. I've also looked at the rotors themselves and there seems to be some sort of heat related little dots on their surface .I will be returning them to Autozone and try and figure out what to get next.
At this point I'm a little concerned with drilled rotors since they tend to create grooving more easily and that leads to uneven pad pressure which leads deposits and eventually to steering wheel shudder, but at the same time I don't want to upset the look of the OE cross drilled rotors. Which one would you recommend?




As I indicated above, mechanic routinely lie about it as rotors for them is heavy customer milking, while not much work added to pads replacement alone.
Each rotor by the law - has min thickness stamped on it. Invest 5 bucks in the tool and you will know the truth.

There's no money to be milked here, I'm doing the job myself, always have. I don't trust other mechanics, I've seem them work




Once again, I sold 300k miles cars and even junk couple of cars with factory rotors on them, so for me -rotors lasting for 4k means something else is wrong.
You concluded brake noise becouse of cheap grease.
For last 8 years I installed several brake pads with no grease at all and they are quiet. I figured out making clean job is crucial and it works for me. No grease needed.

Also brake noise happens only when the car is slowing to a stop and only under very light braking in the cold weather ( it's been below 20s here lately).
