Wilwood Brake Proportioning Valve

$64.99

Product Description

Wilwood Brake Proportioning Valve

Maximum line pressure reduction is 57% with this valve

Prop valve comes with 1/8 NPT to 3/8-24 IF female adapters and will not connect to Mazda brake system without our adapters. Mazda brake lines are metric 10mm x 1.0 inverted flare.

The optional SuperMiata adapter kit includes one 10mm union and two 1/8 NPT to 10mm inverted flare adapters which allows you to install in 90-05 Miata without bending or fabricating custom hardlines. Fittings are all brass to insure a perfect seal without requiring over-torquing.
