Proportioning valve Question

[bburginger]

A couple questions on what to do on my 62 Impala Build. I'm running Wilwood 14" disk w/ 6 Piston Calipers up Front and the 12.19 Disk and 4 piston Calipers in the Rear. Running the Hydratech Hydroboost w/ will wood Master Cyl 1.12 Bore. My question is what I should run for as far as the proportioning valve? Also another question as far as brake lines can I run just a single flare / AN fittings or should it be the double flare type? Any help or suggestions would be appreciated.

Come on guys I'm sure someone has a simular setup? What are you running?

Run the wilwood adjustable proportioning valve.

Brake lines, you can do either AN 37* flare or standard 45* double flare. Each will work fine.

A 37* single flare can only be used with tubing that doesn't have a seam. Any tubing that has a seam requires a double flare. This is to prevent the seam from cracking.

The standard steel lines have a seam. The tubing is made by rolling a long narrow piece on a round mandrel (like a metal rod), then welding it together to form a tube. The weld is the seam which can easily be seen on the inside.

Take a look at the Wilwood Brake Proportioning Valve p/n 260-11179

Go with stock replacement lines unless you want the SS option. If you have access to a hydraulic flaring tool build your own.
