The JH has no native means to alter the balance between the front and rear brakes. The easiest way to change the balance is probably to install rear wheel cylinders having pistons of a different diameter. Since the rear brakes came from a Vauxhall, it's reasonable to think something suitable might exist, but you'd have to research the subject. As an alternative, you could use two master cylinders along with an adjustable mechanical linkage. Perhaps one of our racing members could offer advice on such an arrangement.
Easiest way to do this is with a brake bias valve. These are about $50, available from Wilwood and others, and are simple to install. Just put on the rear line and it will essentially pinch the fluid down and reduce, or increase, the braking depending on how it is set.
But if you need to increase only, that is a different matter.....
