My Old man is restoring/building a 1960s Renault Open Wheeler and we have made our own brake rotors and tophats. Can you have a look at what we've done and offer advice?
We are using Girling Single piston each side Callipers.
Currently nothing will be floating, and the hats are bolted to the Grey Iron disc, is this bad? Should we do some sort of floating bolt type setup between the Top hat and the disc.
Do we need to allow for expansion between the iron of the disc and the aluminium of the hat? Currently the tophat is spiggoted and bolted on.
We were considering machining out any excess iron out of disc once we were happy with the way it was mounted.
thanks for any advice you have
