P-valve CLOSED --> Stiffer spring will do it :)
I'm wondering if I can "pimp" the brake proportional valve by cutting the spring to increase rear brake pressure.
If possible I want to avoid installing adjustable valve for MOT ....

My question is basically:

Will a shorter spring in the p-valve reduce or increase pressure to the rear brakes?

In other words, does the spring close the rear outlet based on a certain hydraulic pressure (differential pressure)? In this case a stiffer spring will increase the rear pressure?
Is the spring deciding the opening of the outlet? This includes Pressure delay between Front and Rear brakes.
In this case softer (cut = less pre-load) spring increases the pressure and reduces delay...

The more I think about it the less sure I am Confused Confused
