quote:Leaking 2 psi pressure residual valve.
The Pantera performance center deliver this valve in their Wilwood brake kit.
What will happen if they are removed?
Practically nothing. Try it and see for yourself. I routinely remove the valve(s) from all my cars. Some are built into the master cylinder and can cause much trouble if a second one like your Wilwood is added. The valve's intent is to keep a little pressure in the lines and the pads fractionally closer to the rotor for quicker brake response, benefitting sleepy drivers. It works OK for drum brakes (different valve, though) but IMHO you'll never notice approx. 0.002 second improvement in disc brake actuation time anywhere except a racetrack. Deleting the valve also slightly increases street pad life, lowers brake temperatures due to reduced drag, and on long trips you may even see a little mileage gain. Its also two less leak points in your system.
