I'm having a strange thing happen with the brakes on my E320. I back out of my garage and down my driveway. I ride the brakes lightly as I go down the drive. It's only mildly steep. After about 10 feet I always feel a catch or a bump from the brakes. It feels as if it's happening on the right front brake but it's hard to say.
Anyway, it only seems to occur when backing and braking lightly to control speed. Generally in those instances in which it occurs the vehicle has been sitting in the garage overnight.
Any thoughts? Is it something warped? Is a wear indicator catching when reversing? This is my first Mercedes and I am very ignorant about their particular issues.
