Customer Questions
I have a 3/8-24 in prop valve and need to convert to 7/16-24 at the brake line. The brake line is 3/16". Is the center hole small all the way through or does it step larger on the 7/16 side for 1/4" line?
The 7/16-24 adapter included in this kit is for a 3/16 line.
Does a 4 wheel disc need a different proportioning valve?
Not when you buy one of our CPP proportioning valves. Our proportioning valve will work with both disc/drum or disc/disc applications. 
What does a brake proportioning valve do?
A brake proportioning valve regulates the brake fluid pressure between the front and rear brakes, ensuring balanced braking power.  
What size fitting is the back of the proportioning valve?
The fitting size is 9/16-18" but we sell a kit that would accommodate any popular size adapter (part number CP2091) which includes 3/8-24", 7/16-24", and 1/2-20".
Do I need a proportioning valve when upgrading from drum to disc?
Yes! A proportioning valve is needed to ensure the proper amount of brake fluid pressure is going to the front and rear wheels.
