VALVE ASSY-DUAL PROPORTIONING

Dual Brake Proportioning Valve for Nissan

Keep stopping power balanced and safe with this OEM‑grade dual brake proportioning valve ️. It meters hydraulic pressure so the front and rear brakes work together, giving stable, straight stops on dry, wet, or loaded conditions. Ideal replacement for tired factory hardware and a smart upgrade when refreshing the brake system.

Why this part is needed

Under hard braking the car’s weight shifts forward. Without control, rear wheels lock early and lose grip. This valve limits rear pressure at the right moment, improving tire contact, shortening stopping distance, and supporting ABS performance .

How it works

Inside is a precision spool with calibrated springs. As master cylinder pressure rises, it allows full flow up to a set “knee point,” then proportionally reduces pressure to both rear circuits (dual). This maintains correct front‑to‑rear bias and helps keep the vehicle tracking straight.

When it fails

Signs include rear lock‑up, nose‑dive, longer stops, uneven pad/shoe wear, pull during braking, spongy pedal, or brake fluid leaks . Ignore it and you risk unstable braking and increased stopping distance.
