Thanks for the explanation and you are hitting on what Bernie asked I try and have done but not yet tested.

The change of spring I sought for my proportioning valve is I am presuming softer (lower pressure actuated) to allow earlier change of bias to the rear brakes.

This is as Bernie suggested and gives me the ability to press harder on the brake pedal increasing braking force without locking front wheels for a higher retarding capacity.

I'll wait for the real road test to see how it pans out.

Cheers
