Disc brake replacement vibration- 2nd warranty claim?
2108 car c63. First service last year I mentioned a wobble/ vibration coming through brake peddle. Car had done 10k miles. Initially tried to get me to pay for new discs/ pads all round at nearly £4K, but kicked up fuss and in the end all discs and pads replaced FOC. Tried to insinuate my driving style but I left it as replaced, but they said unofficially if further issues wouldn’t be covered.
Roll on 11 months, brake vibration back, back in for 2 year service, and I’ve mentioned original issue present. A further 10k miles covered. It’s my daily so genuinely not driven hard. Is this going to be a battle to get replaced again? Why does the brake wobble keep coming back?

sounds like a good shout. Wouldn’t/ shouldn’t MB have picked that up last time before replacing all the discs? Presumably it would be more worn now and fairly obvious after 20k miles? Take it wheel bearings would be covered under warranty at 2 years old/ 20k miles done?

I’m sure it makes sense, but basically the play in the bearing wasn’t enough to feel when driving, but under braking, it let the caliper shift on the rotor and wiggle slightly, eventually causing uneven wear. After the bearing replacement, brake feel has been 100% perfect for 2 years.

E63s Edition 1
Rotors were warped...I don't molest the car either. Always cycle through cold start in the AM, let temps get to operating #'s then id have a little fun. Not quite sure what cause was but 2x full sets on the fronts...1st one was BADDDD vibration, I probably waited too long to take it in but was at 3-4k mi. then the 2nd time they did rears cuz vibration came back a bit but didn't fix soooo back to another full set of the fronts.
My 17 Edition 1 is smooooooth sailing with carbons, back dust like a mother offer and are a bit squeaky but much happier with these.

Dealer came back to me. Mb have only authorised 50% of the cost to be covered. Not happy. Basically said it’s a wear and tear part which is rubbish. Said it’s the fronts only causing the wobble. I’ve asked if they checked the wheel bearings and they are coming back to me. Had to complain to mb customer service so just sent of and email and will follow up with a call tomorrow. On a positive the fronts disc and pads are ‘only’ £884 so a lot less than I was expecting, not that I’m planning on paying anything!

Well, waiting for response from MB customer service now. Dealer says they have checked the wheel bearings and no issue, so no cleaner on route cause.
Do you still check wheel bearings by wobbling wheel and see if play or is it more advanced nowadays? im pondering an independent check maybe?
anyone had experience if MB come back and stick to their guns on not replacing ? What’s the next level to go to?

Wouldn't be surprised if the vibration is caused by uneven pad deposits on your rotors. Did you follow a break in procedure similar to what is called out in the link below after purchasing your car and having the new pads and rotors installed?

If not, I'm quite certain that's the cause of your problem. The vibration can easily be solved by re-bedding your brakes using the same procedure in the link above.

Why hasn’t Mercedes given you micrometer readings from your rotors? Until then, it is complete speculation as to whether it’s a pad issue or a rotor issue (a pad issue will BECOME a rotor issue over time, too).
In my case, with the wheel bearing, the micrometer readings were wildly off on the right front rotor (left was fine), through two sets of rotors. Zero pad buildup was visible or present. That’s when they finally caught the wheel bearing.

And that is often the culprit with performance brakes. Most warped rotor diagnoses are not warped rotors at all, but uneven pad material deposits due to lack of brake use and lack of bedding the brakes. For better or worse, performance brakes are designed to cope with heat and they only perform properly if you get decent heat in them regularly, so you can build a thin layer of even pad material on the rotors and maintain that layer over time. Otherwise, uneven pad deposits and unpleasant brake noise along with vibration is often the result. In some cases it's a genuine issue with wheel bearings or something else, but for the most part it comes indeed down to driving style. The issue is exaggerated in climates where you get snow and salt on the road as the lack of heavy use of the brakes allows corrosion to spread. This is also an increasing issue with electric cars, because the brakes are rarely used due to regen and so they corrode away.

Man I have never heard of this issue before. Do you just contact Mercedes Benz of your country customer service to complain about an issue if the dealer refuses or does not want to do it? I would like to know incase if any issues arise in the future the dealer gives me a hard time about.

Would anything be visible on the disc if this was the issue? The theory does make sense but surely if that simple the dealer would have picked it up?

it wouldn’t surprise me if the stealer was unaware of the break-in procedure required for a performance braking system. Do a quick google search for brake judder and you’ll see what I mean.
You maybe able to see the uneven pad deposits on your rotor. They will be the spotty darker spots on the rotor. If you done the break-in procedure correctly, the entire pad contact surface of rotor will have a dark blue/purple color to it. That is when you’ll know you have done the break-in procedure correctly.

So, cars back with new front discs and I’m £440 lighter ( 50% of normal cost), and no vibration. I think I made the wrong decision saying to replace them but wanted my car back. Merc customer service useless, and I got passed to the AMG CS representative who basically said the decision was final as a wear and tear item, and not covered and under warranty, despite only covering 9k miles and 11 months old.
I requested the original discs and pads to be kept. After I found out basically they hadn’t even inspected the disc with the wheel off prior to replacing, which I’m pretty annoyed with.
Discs and pads look unworn but one disc has what looks like could be pad deposits (?//) on it and are brown when you wipe over it, same colour as the brake dust that drives me crazy. Does anyone know if the brake deposits should be known to mb before replacing? Some pics..
so, next steps? I’m pretty annoyed I’ve just spent £500 if they could have been cleaned up through hard breaking ( break in procedure prev mentioned). Annoyed at my self for authorising replacement. Not 100% sure if this is the issue still?
Anyone have the email of the head of AMG as may ping him an email to see if he would be annoyed if the front discs of his new AMG lasted 11 months subjected to normal road use?
or just leave it and get on with life.....
