Squeaky Brakes and Break-In
Alright, so I have been doing everything perfectly for break-in. Keeping it under about 5000 and 90 mph and giving it a good amount of throttle here and there, easy on the brakes and tranny too (no Kickdown)
My question is why my ****ing brakes are squeaking, it's really irritating for a brand new 100k car. I feel as though this is a common issue. I know how to bed the brakes, but I think I have heard that bedding is not a permanent fix. Any input would be greatly appreciated, I would like to fix this ASAP.
Thanks in advance, Josh.

on the E55 i know all the brakes have a bit of squeak - even the tech who works on my car told me that is standard - its almost like floating rotors on my HD - a bit noisier - but i would take the dealer and ask them to take a look to be sure

Alright, thanks to both of you. I think it is also a winter thing and they squeak because of moisture.

Do a quick search - common issue and some options to help are available. Mine is in wed to change the front pads. Rear ones didnt help. Oddly enough, my squeaking went away after changing the summer rims and tires and driving it in wet snowy weather for the first time last week. No squeak ever since???

No squeaks on my 2010 E63 or new 2012 CLS63... but I always break my brakes in. I like to set them but running up to speed and using heavier force to slow down over a period of time.
Another thing I do not do is coast brake to stop lights as this creates a coating on the rotors which causes the squeaks. When I brake I use those powerful brakes for what they were made for- quick stops. I dont wait until the very last second but I do brake with more force than most. Dont coast; it brings out the squeaks.

The heavy braking should clear off the coating.

BTW, is the OEM front pads ceramic?

What is the proper break in method for these cars? Or could someone point me in the right direction. This was as close as I got via search. Just picked up a black 2012 and that info was missing from the documents I received.
Thanks!

I assume you are referring to the engine rev part of the breaking in. There is either the break in procedure from the manual or the hard breaking in procedure by Vic. To summarize, the one by Vic is to have the engine rev up and down the entire range but not to have the high rev for a prolonged period of time during the break in period.

Wondering how often you guys are having to replace your rotors? Are you having to replace them every time you replace pads? I know this will vary on the way the car is driven but I'm asking because the dealer is saying I need new pads and rotors and the car only has 28k miles (2010 e63). They are saying that there's a lip on the rotors but I'm just wondering if i'm getting taken?
