Brake update

To refresh your memory. I have an 04 E 320 with 15k on the clock. While washing the car and cleaning the wheels, I noticed that the rotors were a series of hills and valleys. I thought that this was a problem.

Today the car is at the dealer and they insist that this wear is "normal". There is a combination of metallic pads and "soft" rotors that cause this behavior. I checked with other independent MB shops & they concur, that indeed this is normal.

The dealer also told me that the rear pads were worn and needed to be replaced (at 15k miles, rear brakes, and metallic pads?). Cost of this exercise is $300 to replace the rear pads ($119 for the pads and the balance for 2 hours @ $95/hr labor etc).

Part of the reason I am concerned is that I thought that this car came with maintenance included, so why am I being charged for these pads? Never mind that the rear brakes usually wear more slowly than the fronts.

What am I missing here?

Thanks for your input.

Sorry to burst your bubble but read the terms and service descriptions the free Maintenance Program covered. It states that brake's are wear items and will not be replaced for free (there are too many variables to take into account when looking at brake wear). I would replace the pads when the On board computers tell you to do so. You will get a message in the instrument cluster letting you know.

The wear of the rotors is my biggest concern.

Thanks

I think there is a TSB out for premature wear on rear brakes. don't know if it applies to your car but do some search here for more info.

The grooves on the rotors are a normal sign of wear and tear, I wouldn't worry abut it. I use this as an indicator for me after I break-in the pad/rotors.

Unlike BMW, MBUSA does not include wear items (i.e.: wipers, brakes, etc.) in their free maintenance plan. SBC applies additional force on the rear brakes than a conventional braking system and as such the rear pads usually wear first. There is bulletin P-B-42.10/48 JUL04 but it is for information only. Basically it addresses premature rear pad wear prior to a warning message being displayed in the instrument cluster and states that revised pads be used for replacement.

Thank you

Thanks to all of you for the replys. I was not aware of the way the rotors should appear. I am used to them being smooth unless there is a problem. The dealer replaced the rear pads and the car is back.

I guess I misunderstood about the maintenance coverage is for this car. I have an Audi that everything including the brakes and rotors are covered. The only time that warranty does not apply is abuse or damage.

Once again, thanks

My sales rep was very explicit when he sold me the car. Brakes and tires are not included. But, I was also surprised to see the brakes wear so fast. They will replace the brakes for free if you are under 10K though when they go.

I wonder how much the revised pads help in extending the brake life?
