I believe Sherwood Kahlenburg nailed down the disc brake facts perfectly. There is one oddity in the parts books that maybe someone can explain to me though. In the most common '55-58 parts book, on page 5-7 are shown front AND rear exploded wheel cylinders and both are noted "Used with Disc Brakes". For what models in these years were discs used? Or were they just stuck in the books in case some of the NASCAR racers wante the option of putting them in their Chrysler 300 race cars? Wayne |
