Combination Proportioning Valve – Adjustable

Combination proportioning valve designed to simplify mounting, plumbing, wiring, and brake bias adjustment in custom brake systems. This valve maintains full isolation between front and rear brake circuits and is compatible with tandem outlet or dual-mount master cylinder assemblies.

The rear brake circuit features a single 3/8-24 inverted flare inlet and single outlet with an adjustable proportioning valve to fine-tune rear brake pressure from 0 to 57 percent reduction. The front brake circuit includes a single inlet with dual outlets, allowing it to be used as a single outlet (with one port plugged) or to split plumbing directly to the front calipers.

Constructed from aluminum and steel with a clear anodized finish for corrosion resistance and durability.
