Yes, you read right - I hate my 2002 ML55 right now! :banghead:

My new front Mercedes OEM rotors and OEM brake pads are squealing like a deranged pig on crack cocaine!:crybaby2:

It's doing this to me:

ML55 Front Brakes:1poke:FAR888

I'd like to do this to it right now:

ML55 Front Brakes:bash:FAR888

I don't have access to Mercedes paste out here in West Africa so don't even suggest it or it will lead to this::argue:

My sister is currently in the US and I was considering asking her to buy me Posi Quiets, which some members have used with success.

I can only seem to find them online at the dreaded Ebay.:eek:

I was wondering if I could buy them online at another trusted site used by one of you.

I'd be grateful for your responses - Please help me kiss and make up :sloppy:with my ML55 again!:)

ps. I love Smilies...:surrender:

ouch FAR. I'm sad for you, but glad you could let the glory out here on benzworld. How many miles on the pig brakes? mclass, understand, FAR is an attorney by trade, so details and that devil that lies in them is very irritating to him; I understand processes and exactness in my own profession so it is frustrating to repeat something you feel you shouldn't have to redo; IF you did it right the 1st time. FAR these OEM's, were they shipped from US, Europe, or you get and Africanar deal? Just helping you think here. Just my .02, but I would try the paste and tons of cleaner before putting on new shoes if at all possible--if it doesn't make $'s it doesn't make cents. FAR, you have 1 of the best looking stock AMG's in this forum; squeaky or not, @ least it's not an AIG.

Thanks for empathising oreif!:)

I'm not really mad just embarrassed and irritated.

The rotors and brake pads are Mercedes OEM bought in the US.

Something is very wrong. The new OEM pads don't squeal a peep. You're not even in cold weather, a condition for which these pads squeal. I'm surprised at your pig brand pads/rotors. Take the wheels off, remount then and retorque to spec. Overtorquing is known to warp rotors. maybe you're at some threshold, I don't know. But something doesn't sound right.

Also, I'd get some kind of paste on the back of those pads. It doesn't have to be MB. Personally, I like the spray-on types. Keep us posted.

Looks like you got some troubleshooting to do. But in the end if it ends up being pads, my Posi-Quiets have been pretty good. Only some squealing backing up on a rainy day. Best of luck!

Lol, I thought to myself.."I'm going to have to tell ANOTHER person what we did to my father's AMG to stop it from squeaking...", but you saved the day. Thank you, good sir. :thumbsup:

Darkmann, you may be on to something about installation/torquing of wheels etc.

Yesterday, after work, I drove along the beachfront with my tinted windows UP and wearing DARK SUNGLASSES:cool: so no one would see the owner of the ML55 with squealing brakes!:D

As I drove, I got so irritated with the squeal that I slammed on the brakes hard enough for the ABS to kick in and after that....NO MORE SQUEALS...:dance:


.....I felt more comfortable and rolled my windows down, opened my sunroof and took off my dark sunglasses...proud, once again, to own a Mercedes ML55.......10 minutes later....the squeal was back with a vengence:elefant:........I quickly closed my sunroof, rolled up my tinted windows and donned my dark sunglasses:cool: disguise once more.:crybaby2:

I will have the installation of the brake pads/torquing of wheel bolts checked at the weekend after I have bought a big hat and a beard to disguise myself as I drive through the streets on the way to my mechanic.:p

Were the new rotors "surfaced" before install??
I'm not too sure about what you mean by 'surfacing' but nothing at all was done to the rotor upon installation.

The squeals appeared approximately four months after installation.

Indeed ML-O-PHILE!

Please indicate whether you bought them online and where you bought them - Is Ebay safe* for this sort of thing?

Thanks!:thumbsup:

* 'Safe' in this context (Ebay) is of course a relative term!:D

Aye I got those pads on ebay. $92.00 for complete front and rear set. The seller was propartsusa. Was a pleasant transaction.

It also appears you have discovered the Unsanctioned Mercedes secret to breaking in pads. (although your problem has returned) When I was Q/A for a Mercedes dealer in the early 90's, MBNA would have me apply "firm" pressure on the brakes from "generous" speeds two or three times. (translate this for yourself, lets just say WOOOOOOHAAAAAAW!) This solved all sorts of brake noise issues related to rotor glaze, poorly seated pads, etc.

Mercedes Q/A in my early 20's... It didnt get any better.... Lots of stories there....

FAR, although I haven't done it on the ML yet (this weekend I hope), I had a similar problem on my car.

I took the wheels off, had someone slowly spin the rotor while I gently applied an orbital sander with 100 grit emory cloth on it to the rotors, it put a really pretty swirl on them, just like new ones have. After doing this to both sides of all 4 rotors the squeal was gone!!!

Mind you I didn't let 'her' drive it after that either, so the noise may have been related to the 'loose nut' behind the wheel too. ;)

You're killing me with the smileys. If it is any consolation. I'm wearing sunglasses with a mustache too as every stop means a loud, embarrassing shreaking squeal. My only consolation is that I do need to change out the brakes anyways.

Interesting: an over torqued rotor can cause warping... can warping cause squealing?
