Review on Black Racing Lever Type Adjustable Prop Brake Bias Adjuster - Hypertune Brake Proportion Valve by Kyle Hong

I bought this to regulate the rear brake pressure on my 1935 Chevy hot rod. I was surprised to find out that the control was exactly the opposite of what you wanted it to do. The valve must be adjusted to the stop so that the brake pressure does not decrease. The only problem is that the valve has no stop in this position. It just goes completely out of the body. The adjustment knob has no lock nut to secure the adjustment. This is very bad design. I would like someone to post this information if I was about to purchase this item. I bought it at the beginning of a car project. Seven months later I find out how bad it is. Please save your money and keep looking!
