New rotors and ceramic pads are squealing and sounding like they are grinding
A local shop Installed brembo rotors and ceramic pads on the front and rear and I’m maybe two months In and they are squealing and sounds like grinding as of the last few times I drove it. The way the pads are wearing look kinda strange like they are rolling as they wear it’s kind of hard for me to explain. I’ll try to get a pic in the am. I’m wondering if they were installed properly and I hear people say so many things about the direction of the holes determines how they are installed then I also saw that it has nothing to do with the direction of the holes it has to do with the direction of the teeth in the top of rotor ?? Anyone dealt with this squealing or sounding like it’s grinding ? I’m going to have the shop look at them again but i think it’s coming from the front most likely but I am pretty upset at the fact they are squealing and embarrassing after less than two months I think They were installed wrong or faulty parts I can’t get into a shop for a few days due to work so I figured I’d ask on here thanks

Just got back from place and they blamed it on the pads and my parts of course I knew they were going to do that, now I still think they were either installed wrong or I was sent two of the same side. I took pictures to show that the holes in rotors on both sides are going in opposite directions don’t mind the ugly calipers lol getting resprayed as soon as I fix this brake issue lol Front left Front right

Think the cross drill pattern in your front rotors looks just like mine. I have Brembo rotors too. I had big problems with vibration after first install. Was given a replacement set by online seller and no probs after that.

that’s what I was thinking I hope the online seller will replace .
I don't know anything about the squeaky brakes but yours looks the same as mine (the rotor direction, not the calipers :p )
Those calipers are killing me lol I’m going to get those and my one scratched wheel finished at the same time here soon but the brakes and the way they sound right now are even worse. So your rotor direction is to the back on the left and to the front on the right ? Just looks off to me but I’ve never really paid attention.
I These look a lot older than 2 months
these are only 2 months old apparently I feel like they never changed the rotor when I checked the backs they still have some shine, no rust like the fronts and they were done a week apart, I’m hoping they didn’t just charge me and not change it all. I’m going to drop off at my Mercedes mechanic Friday for a trans flush so I will ask if those are the oem rotors bc if they aren’t the brembo ones I gave them to install we have a big problem but once again I don’t know if that’s normal rust for two month old rotors. Thank for input guys
It that a lip on the inside diameter of the rotor? In 2 months you shouldnt have that. Is there brake grease on the back side of the pads?
What's up with a trans flush? That's a great way to ruin a transmission You should change fluids every 60-80K miles.
looks to be a lip there and that’s exactly what a local mechanic said, he stated should not see that after two months. The place that did it claims the pads are bad? And that’s not grease it’s actually brake dust.
as far as the trans flush, I bought the car with 97k milesand apparently it was never changed and I have 102 now the Mechanic that’s owns a Mercedes repair shop asked me to look into to see if ever changed so I called the few dealerships that was on car fax to ask and confirm if was ever changed and it seems like it wasn’t according to the records they have at the two different dealerships that serviced this car prior to me owning. I’m also changing trans and engine mounts. I wanted to upgrade the trans and do a tune at renntech, but before I did that I wanted to have the brakes handled, flush trans and replace engine and trans mounts.
Brake grease is put on the backside of the pad and moving contact areas to prevent squealing, not on the wear side. Did your mechanic use any?
Again DONT EVER flush a transmission, but do change the fluid and filter. Flushing a high mileage transmission is a high likelihood of destroying it. One way to reduce possible damage is to change the fluid in the pan but not the torque convertor and then in 5K miles change the fluid again. Of course on the these newer trans that is a real pain in the **** since you have to fill thru the drain hole with a pump and the blue trans fluid is expensive.
Ceramic pads are more aggressive and will wear the rotor much faster. You might want to try a slightly less aggressive pad replacement.

im sorry, forgive for being mechanically illiterate lol but I think that’s what they meant was to have the fluids changed and filter changed for the trans. They quoted me 550 for the trans fluid that was supposed to be changed he said at 70k does that sound right ? and as far as the brakes I’m really pissed that this became an issue I bought the rotors and pads at same time in a brembo kit, I assumed the pads were made for the rotors because they came together as a kit my concern is that the rotors were never changed. Like they said they changed em but really just changed my pads in there on the same Mercedes rotors so I can’t tell by looking at them if they are Mercedes or brembo so I’m hoping the mechanic I’m going to see can tell me that. If they were never changed and they are still the Mercedes rotors then I can handle it how I have to but I have a suspicion they kept my rotors and just changed the pads
Turns out they are the brembo rotors and I can’t understand why it’s making that grinding noise and squealing. I’m guessing I can try new pads, any suggestions ?
