Review on Wilwood 260 8419 Adjustable Proportioning Valve by Todd Adams

I installed this metering valve between the master cylinder and the rear brake hose. Great little safety improvement as the factory manifold doesn't have a pressure gauge or limit so every time you apply or brake you send full pressure to all 4 brakes. I have power discs on all 4 wheels and without this valve my rear discs would lock up first. Not good. so now i can adjust the braking power that goes backwards!
