D-5

A interesting thing that I noticed after driving my friend's SL55... there is absolutely no virbration and buzzing noise from the brake pedal!? What happen to the SBC Pump? Where did it go?? And after my E55 did the recall on brakes, the buzzing noise comes on more often than before, like every 2 times applying the brakes (If I remember correctly, I believe it used to be every 5 times..) Also does anyone know the fix to squealing at low speed without braking? I wanna ask you guys first before going to my stealership, I can already imagine what they're going to say: "Its normal, that's just how the way it is, there is nothing to worry about"
