Brake Proportioning Valve

Description

The Wilwood 260-8420 Adjustable Proportioning Valve is designed to provide precise brake-line pressure adjustment in compatible hydraulic brake systems. Its compact forged billet design combines strength with a six-position lever for quick, repeatable brake-bias adjustments.

Pressure adjustment ranges from 100 to 1000 PSI, with up to a 57% decrease in line pressure. The lever clicks into six preset positions, allowing consistent adjustment without relying on an unmarked setting.

Vehicle Fitment

Application: Designed for compatible custom, performance and motorsport hydraulic brake systems requiring an adjustable proportioning valve.

Fitment Note: No specific year, make or model fitment is specified. Verify brake-line size, thread type, hydraulic configuration and system compatibility before ordering.
