Quote*.................. Now during this winter I intend to replace the master cyl seals and tackle the brake proportioning valve.
I know there are early and late prop valve kits what do you think my
13th April 1965 car is likely to have ?
I will measure the adjustment on the prop valve before I take it apart but wondered how people set these up, is it just trial and error? or is there some science behind it, as I think that a properly set up disc / drum system is unlikely to need a power booster.
there is usually a fair amount of pitting/corrosion in the bore of the proportioning valves. I have never been able to get them to be leak free after putting in a kit. Jim Cowles does a great job of restoring these.
