For brake systems utilizing CPP’s Proportionalve Valve, use this tool when bleeding your brakes to lock the valve in place and keep the valve from tripping.
Simply remove the warning light switch (white plug) on the valve, then screw in this tool while bleeding your brakes. After the bleeding process is finished, replace the warning light switch. Save yourself the headache of having to reset the valve. Works with PV-2 #PV-2A, PV-C #PV-4, #PV-4A and PV-4C .
