but screw my theorys....I did the brake pads today, first time I've ever taken a wheel off of the car as well as my first Mercedes...I like what I saw in there, the Girling caliper is awesome in it's simplicity. It took me 45 minutes to do both sides in a parking lot with jacking and bracing and so forth. Brilliant design! Much much simpler than my wifes BMW 325i brakes..I am blown away by the logic
