Drove my SL a week ago and it was perfect. Jumped in it today and the brakes are juddering every time I use them with it most noticeable when braking from high speeds. You feel it through the pedal and through the floor but not really through the steering wheel. Car has just had new discs and pads (Mercedes genuine parts) about 500 miles ago. Car was last driven in the dry and parked in my garage for the last week so no rust on discs etc. juddering feels more than that anyway. I think the lack of movement of the steering wheel indicates an issue with the rears rather than the fronts, but I'm open to advice on that. A brief visual inspection reveals no issues although I really need to get the wheels off and gave a proper look, Anyone any ideas before I take it to be looked at? Is it worth trying a bed in procedure (2 lots of 10 60mph to 10 mph stops with a cool down procedure in between?
