Can u just remove the springs in the valve for full pressure or just the rear spring for full rear pressure
Any info would be great thanks

 

You could but the rear brakes would lock up before the fronts. Or. Install an adjustable valve in the rear circuit. You can bypass the rear of the distribution block completely but the brake warning light will stay on as it'll think the circuit has failed. You could T off the input to the distribution block and plug the rear outlet. Put the adjustable valve in the rear circuit. It's a great addition to the brake system.

 

I want backs stronger for sure big tire skinny in front
So I can just pull the spring out for full rear pressure and what spring the one closer to the firewell or one facing front of car

 

Any pics of this
Or pics of valve mods
