CPP brake proportioning valve

[fatgump]

I installed all new brake lines, CPP brake booster and proportioning valve. I have fluid leaking from the plastic sending unit on top of the proportioning valve. Does the proportioning valve need to be replaced or the sending unit.

Thank you,

Is it actually leaking from the valve or is it on the fitting which fits into the rear of the valve where the line which supplies the rear brakes fluid ? I just went through an ordeal involving CPP and a defective proportioning valve which at first appeared to leak from the switch but was determined to be at the top of the fitting where a small plastic piece was installed in their valve. They sent me a metering valve kit which will not fix it then I finally got tired of their tech guys treating me like crap so I purchased one from them and waited until CPPJEFF got me a refund! Goodluck post what you find please....

The leak is from that plastic piece. I purchased the brake booster and proportioning valve from Jeff, The Chrome Guy here in Arizona. He is going to replace the proportioning valve for me.

Good call as that is a defective valve if it is leaking from the plastic switch.
