A couple of questions on the M4 if anyone can answer. Twice during driving in moderate rain/wet and for several miles without having to apply the brakes, that when I did need apply the brakes to slow/stop quickly/promptly, I had to push HARD on initial application to avoid hitting the car in front of me. Immediate successive applications were normal, until several miles later, (again in rain and after not having had to apply for a while) and the same thing occurred again. Is this normal, or do I need to 'seat' the pads properly? Was not told CCB pads needed that procedure. Only 1500Mi on car. Also, on a very tight turn/circle, I notice a much larger circle/area needed to turn 180+ degrees. Is that normal? I've not seen any thread or comments on either of these topics. Help appreciated, thanks!
