I am installing the Forte Hydroboost setup with the Wilwood disc brakes. I would like to incorporate a brake line failure switch and also set the bias on the brakes. All the adjustable brake proportioning valves I've found only have a brake light switch. The common brass proportioning valves/ distribution blocks have the brake failure warning switch, but they are fixed with regards to reducing the pressure to the rear. Any suggestions? Does anyone know of an adjustable proportioning valve with a brake failure switch?
