Wilwood 4444/30 260-11179 Proportioning Valve - Balanced Brake Control

In this review of the Wilwood 4444/30 260-11179 proportioning valve, the bottom line is practical: this compact valve is aimed at enthusiasts and professional installers converting or fine-tuning disc brake systems who need reliable front/rear brake balance. The reviewer found the valve straightforward to install and well built, making it a sensible upgrade when paired with Wilwood disc brake conversion kits. Ease of adjustment and a precise balancing range are the single biggest reasons to choose this unit for a street or track application that demands consistent brake bias.

Key Features

• Purpose-built proportioning: Provides adjustable front to rear brake bias so a builder can dial in braking balance for disc conversions or custom setups.
• Compact packaging: The small footprint and supplied single unit packaging make it easy to tuck the valve into engine bays or along brake lines without major rerouting.
• Durable construction: Wilwood Engineering designs high-performance brake components, and the valve reflects that heritage with a solid feel that supports long service life.
• Simple adjustment: The valve offers accessible adjustment for front/rear balancing so a mechanic can make tuning changes quickly during testing.
• US manufacturing: Made in the United States, which appeals to buyers who prioritize domestic production in performance brake parts.

Who It's For

This valve is best for car enthusiasts, custom builders, and professional installers working with Wilwood disc brake conversion kits or aftermarket brake systems who need reliable bias adjustment. It suits street, autocross, and light track use where precise brake balance improves control and pedal feel.

It is less relevant for vehicles that use integrated electronic brake proportioning or full ABS control where the mechanical valve would be redundant. Buyers needing a complete master cylinder or ABS replacement should look elsewhere for a matched hydraulic assembly.
