Made from corrosion-resistant brass and engineered for flexible mounting, this universal valve is built to interface with standard master cylinder and caliper plumbing while fine-tuning front-to-rear brake pressure distribution.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the PV4 improve braking balance?\u003c\/h3\u003e\n\u003cp\u003eThe PV4 reduces the risk of rear brake lockup by adjusting the hydraulic pressure routed to the rear circuit relative to the front. By proportioning pressure correctly it helps the front and rear brakes engage more predictably under heavy braking, improving controllability.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eProportioning action calibrated for disc\/disc systems\u003c\/li\u003e\n  \u003cli\u003eReduces rear wheel lockup tendencies under hard stops\u003c\/li\u003e\n  \u003cli\u003eWorks inline with existing master cylinder and lines\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat connections and fittings does this valve use?\u003c\/h3\u003e\n\u003cp\u003eThe PV4 includes five threaded ports to attach to the master cylinder, front and rear brake lines, and parking brake or auxiliary lines if needed.
