Detailed Product Overview

This brake master cylinder is designed for 2007-2014 Ford Edge and 2007-2015 Lincoln MKX models with front disc brakes. NM4163A replaces the hydraulic component that converts pedal force into brake pressure, helping maintain firm pedal feel and predictable braking response. The aluminum construction supports durability, while the included reservoir, cap, and seal simplify the replacement of the hydraulic assembly.

This part cross-references Ford OE part number 4G7Z2140AA for the same application.

What It Helps Fix

• Low or sinking brake pedal
• External brake fluid leakage at the master cylinder
