So I bought my 2014 cls and had problems with the car kind of vibrating over 50-60 mph so I figured out the rims were bent got them fixed and fine no problems. Now when I’m driving and I slow down it sounds like the brakes are vibrating almost like the sound of the bent rim. So I spoke to my dad and someone else and they said there could be a problem with the abs because there’s plenty of pad left. I’m not a mechanic at all so I don’t know much. And this morning I went out to the car and there’s some buildup in some of the slots like maybe from the pad and looked like some black buildup outside of the pad and caliper. I ordered new front rotors, pads and sensors should be here Wednesday but I’m wondering if that is the problem or something else maybe. Has anyone had any issues with the brakes on this car thanks
