Hi all, My daughter has a 2000 230 slk and took it in for a brake job. She brought in with her 4 drilled and slotted rotors and ceramic pads. The shop did the job (not MB dealer) and now the car pulsates with medium pressure coming to a stop plus the steering wheel shakes and there is some squeeling too. All the parts are brand new, any idea what the problem can be? Thanks for any info.

John
