I have to disagree with your comments that braking was not one of the best features of this generation of bmw. By this generation, you're referring to the E30, E34 and E32.These three cars shared alot of similar components across the chassis. They even share engines - the M20, M30 and M70 (basically 2 M30s sandwitched together). Many of the subcomponent manufacturers for everything in the cars, were the same, If the E34 had world record winning brakes, then how is it possible for the other cars in the same generation to be far behind ?I believe something in your old car's stock system was not optimal on your car. In fact it seems obvious to me.Take heed to the comments Alan made that upgrading to brembo callipers did not make much of a difference. The brembo callipers are able to apply force to more of the brake pads (in terms of surface area) and thus apply more force to the brake discs.Changing the size of the rotors would not have made any difference to the contact area between the pistons and the pads, and the pads and the discs, unless you had large pads as well. However, larger callipers generally need to come with larger pads so that was probably done to begin with.Probably the stock brakes you had were very close to the brembo's performance, and in any case, only made a difference in the pre-lockup part of the braking process, which didn't amount to much......MKMD428, what are your thoughts now ? Have you done the mc (master cylinder) tests I suggested above? Did you do any other tests ? How is your brake fluid's quality? Have you done piston bleeding?</blockquote>
