AC Delco-Style Combination Valve with Wire Connector for 4-Wheel Disc Brake Systems

Upgrade your braking system with this AC Delco-style PV4 proportioning valve, a direct factory replacement designed for 4-wheel disc brake applications. This OEM-style combination valve ensures proper brake fluid distribution, optimal braking feel, and enhanced vehicle safety.

Key Features & Benefits:

✔ OEM Factory Replacement – Exact AC Delco-style design, based on the AC Delco 172-1361 disc-disc valve.
✔ Durable Brass Construction – Corrosion-resistant internals and external housing for long-lasting reliability.
✔ Pre-Set for 4-Wheel Disc Brakes – Optimized brake pressure balance for front and rear disc brake setups.
✔ Low-Pressure Shutoff Valve – Enhances safety by preventing fluid loss in case of hydraulic failure.
✔ Integrated Brake Warning Light Switch – Alerts the driver when hydraulic pressure is compromised.
✔ Includes Wire Connector & Pigtail – Ensures quick and easy installation.
✔ Not for Disc/Drum Applications – Specifically designed for 4-wheel disc brake setups (not for front disc/rear drum configurations).

Why Choose This Proportioning Valve?

🔹 Essential for 4-Wheel Disc Brake Conversions – A must-have when upgrading from drum to disc brakes.
🔹 Safer than Adjustable Valves – Aftermarket master cylinders with built-in adjustable proportioning valves lack a low-pressure shutoff feature, which can compromise safety.
🔹 Reliable, Factory-Style Performance – Engineered to match OEM specifications for superior braking.

Application Compatibility:

✅ GM, Chevy, Buick, Oldsmobile, Cadillac, Pontiac, and GM Trucks.
✅ Designed specifically for disc/disc brake systems using a GM-style master cylinder.
