Proportioning Valves & Accessories
The back of proportioning valve is 9/16 fitting. Is that for the front or rear brakes? Do you sell a reducer to fit a 3/16 brake line? And is that adequate in size for rear drum brakes (3/16) 1970 ford F100 what size do I need for front disc brake ( brake line) I purchased your 7 inch power booster and master cylinder combo with proportioning valve
On the back of the proportioning valve part #PV24- the 9/16-18 fitting Is for the rear brakes. You can use part # CP2091 to adapt to the smaller fitting size. Yes 3/16 line is adequate for rear drum or rear disc brakes.
Is there a difference in brake master cylinders from a disc/drum to a disc/disc, eg bore dia.) or is the difference in the proportioning valve. Thank you.
Hello Greg and thank you for showing interest in our products. There is no difference in master cylinder between disc/disc or disc/drum, there is also no difference between the proportioning valves.
When you purchase a brake booster kit and are going to run disc/disc do you have to remove a residual check valve from the proportioning valve
Hello Greg and thank you for reaching out. This was true pre 2019 when there was residual valve that was located in the rear plug. Now our valve come with a relief valve that does not require you to do anything when switching from drum to disc.
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.

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?
