Wraped front rotors question
Has anyone had problems with the front rotors with the AMG brakes? My '07 has 5,000 miles and I'm getting a slight shimmy in the steering wheel braking at 40-50 mph. This is the 5th MB I've owned and never had this happen before. One local dealer said this is normal that is the spring rate causing this. I can't believe some of the stuff some techs can come up with. Taking it to another dealer next week. Hopefully they will take the time and actually try and find the problem.

Huh?
Idye,
I have been building cars since I was 16... And that explanation is rediculous... On anything from a Hugo to a race car no spring rates would cause that... You have warped rotors...
When you first got the car, did you jump on the brakes real hard before the pads had a chance to seat? You have little contact area when both pad and rotor are new.. and that means the load is placed on that small area... Temps rise dramatically in spots that have contact on the rotor, and there you have the warpage.
If the dealer won't replace the pads & rotors... I suggest you contact MB.

I have also been involved in the mechanics of cars most my life and it's amazing what some of these techs will try to pass on to you. I purhased the car with 4000 miles on it so I can't say how the brakes where set in when new. I'll let you guys know what the dealer tells me on Wed.

I've gotten no where with my problem. Service techs just want to blame the tire size for what I'm experincing. No explanation what causes the steering wheel to shimmy when you lightly touch the brakes. I'm at a loss now as to what to do to try and eliminate this.

It has nothing to do with your suspension (
), and if it had anything to do with your wheels you'd feel the shimmy on ACCELERATION and AT SPEED. If you only feel the shimmy on deceleration then its brake rotors, PERIOD. Its about as hard to diagnose as a compound fracture. Oh that's your bone sticking out of your leg? Must be broken.

I've only had this car for 2 weeks. I've just about decided to dump it. When this MB is gone there will never,ever be another Mercedes in my garage. This is the 7 MB I've owned and everytime I have any issues with the cars it takes forever to get it resolved. I'm tired of fighting it. You shouldn't have to push a service department to correct a problem that is clearly detectable and fixable.

I would have quit after 2-3 bad cars, not 7...........
My used '05 SL55 has had absolutely no issues as of yet............
(other than the fact that it needed the ECU/Pulley/IC Pump upgrades........for more power.)
Oh, and we removed the "Deer-Whistles" the previous owner installed.....We had to in order to install the 2ndary Intercooler.

That's a shame that this dealer treated you like this. Was it the same dealer that you had the other issues with? This problem sounds pretty obvious. It was warped rotors. Period, end of story. You shouldn't have had to pay for it, but if you did...the rotors are $110/each, and the pads are $200. S, I would have just handled it myself. The SL55 is just too good a car to let this group of idiots destroy your views of the car. I still would contact MBUSA and let them know what happened.

Ditto............Warped rotors is no big deal..........new ones cost about 150 each...........I personally would not re-surface the old ones.......too thin then........"The more rotor meat........the more it will absorb heat".......you can quote me...
P.S.........the Porsche is a nice car........

The dealer sized you up, and was not motivated to help you, I wonder why?
Try telling the whole story...
