Brake Bias Valve

Hi all,
Does lowering affect the braking via the brake bias valve. ie the lower you go the more brake bias goes to the rear?????

I think this is the case - however there is a nut / bolt attached to the trailing arm which you can move in a slot, so that when there's no load in the back of the car, the bias valve is still open even though the rear of the car is lower…

Can anyone else confirm?

Yeah your right

To adjust the brake balancer, simply park your car on level ground, and loosen the 13mm bolt/nut combo at the end of the spring. Slide the bolt/nut until the spring is just snug between its end points. This is the factory setting. For fine tuning, slide the bolt/nut up to give more braking to the front brakes, and down to give more braking to the rear brakes

Can be a pain when car is on floor because I couldn't get under it! as you can't obviously jack it up.
