Brake proportioning valve

[joe garland]

I can't tell if I am making a differance when I try to adjust the valve, any suggestions?? Where is a good starting point, all the way shut?

Thanks for any tips!

Hi Uncle Joe,

Here's a quote from the Wilwood FAQ page:

Q: When do I use a proportioning valve?

A: A proportioning valve is a pressure reduction device. It is typically installed in the rear brake line to reduce braking efficiency and compensate for premature wheel lockup; a result of incorrect front to rear brake bias. An adjustable proportioning valve permits incremental adjustments to fine tune brake bias.

You need a place to stop from speed that has no, um, fixed barriers, if you know what I mean. If you lock the back tires under braking the car is unstable

What you need to do is to get the fronts to lock up just before the rears.

Regards,

Tom
