[NASSTY]

I had my rear end rebuilt by a jag specialist when I built my kit so the rear disks work reasonably well but as this discussion has stated it's pretty hard to adapt donor brakes to cobras and get the balance right. It's certainly not right in my cobra. Given our jag diffs are 30 odd years old I wanted to make sure they were working properly from the start.

I know of a fair few cobras, with jag diffs and falcon master cylinders, who have removed the proportioning valve altogether to improve the brake balance and their fronts still lock up first. I'll plan to do this mod myself when I next change the brake fuild.
