To fit Girling type rear brakes to an earlier car I'm told that you need to machine down the backplates.
Having done this I've discovered an oddity and I'm after advice.
I turned down the brake backplate mount so that it just cleaned up the boss for the spring mounting pin. This gives an OD of 4.25 whereas a Girling backplate needs 4.00. See the picture. I wouldn't want less metal around the pin.
Did Austin alter the spring or pin position for Girling brakes or am I unlucky in trying to adapt the "oval backplate" 1935-ish brakes? Or perhaps this is normal and I'm worrying unnecessarily!
Thanks
Charles
