C55 brake squealing please help
I have had my c55 for about 2 months now and about a month ago i started hearing my brakes squealing at low speeds most of the time not always and its getting annoying. The previous owner said he replaced the brake pads but I don't know which ones he used. The other day I took my brake pads out and cleaned my brakes with brake cleaner and used some brake disk quiet on the back of the brake pads. It still seems to make some noise. I'll post some pictures of my rotors and fd below. Any advice or suggestions would be appreciated. Thanks.

Seems Rotors already gone, before he had replaced the pads..!,
pads face looks harmed with Rotor groove lines,,
i think you need to replace the Rotors & Pads in the same time, that will definitely save time & helps a lot..!!

Zayed is 100% in his answers. I bought brembo pads last time and regret it. OEM has the most brake dust but they work really well for street use and they are matched to the rotors.

It really is dealers choice on the matter. I have found that certain setups work better together than others. There is a lot of difference between manufactures/models of pads a rotors in regards to their materials. you can run into issues of a pad that is so hard you go through rotors like crazy or they make noise no matter what you do. After all the setups I have run on all my cars I have found that stock is usually the most problem free DD setup you can buy.

Your rotors could be warped, causing an imbalance of rotational mass. Could also be your flex disc or motor mounts going out.
Essentially there's a lot of things that can cause vibration, your best bet is to search the forum and try to figure how exactly when the vibration is happening, at what speeds and what it feels like.. Pulsating, slight vibration, thudding.. Etc

It's possible, if the rotors warped to the point of failure then yea you'd feel something. Essentially you'd feel the pads bite once every rotation. Highhhhly unlikely but in theory possible. As I said before its probably the flex disc, motor mounts or some bushings somewhere that are shot.

Or it could be a wheel out of balance a bad tire or a million other things. We could speculate all day but with the responses from the OP in the thread I would suggest he go to the dealer and get a PPI.
