Re: Dual Pin brakes on rear - not factory
Mike----
I never said that you were saying that the dual pin rear calipers were factory installed. However, someone might infer that they were, in some way or another, originally installed. I wanted to make it very clear that they were not.
The GM factory J-56 brake system was not necessarily the "ultimate" brake system for a Corvette and it was certainly not advertised by GM as such. It was simply a "better than stock" performing brake system. For some forms of competition it might be quite adequate; for others it certainly wasn't adequate. An important consideration here is that the J-56 system that GM offered had to be 100% ok for street operation. All the cars that GM sold to the general public had to be, more-or-less, suitable for street use, even before there were laws which heavily dictated this. So, systems which were suitable for all out racing might not be suitable, at all, for street use. Generally, the more severe the racing application, the less suitable that some system designed for it is going to be for the street.
So, the factory J-56 system was simply a braking system "between" a stock, street system and a system for all-out racing. GM offered the stock system, and the J-56 system. If you wanted or needed something beyond the capabilities of J-56 you had to come up with it yourself from another source.
Could GM have "upgraded" the J-56 system by using the dual pin style calipers at the rear in conjunction with the same pads as used for the front? Yes, they could have. In fact, they could have done it quite inexpensively and quite easily. I'm sure that "crossed someone's mind". However, my guess is that they felt that the system as it was constituted for so many years represented the best "balance", etc. of what they were trying to offer in a system suitable for street operation.
