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

After three days of changing master cylinders and trying to figure out why my rear brakes weren't bleeding, I realized that this stupid thing won't leak brake fluid unless it's fully open. 1/2 turn locks the rear brakes completely. I installed it on a custom jeep and was hoping to avoid using a metering valve for simplicity, but ended up with a prop valve to get it working. Don't waste time fumbling with returns.
