Detailed Description

This brake master cylinder is built for Hyundai Santa Fe brake system service where hydraulic pressure loss, internal bypass, or inconsistent pedal feel has affected stopping performance. NM55159 is a direct replacement for 2001-2004 Hyundai Santa Fe models equipped with front disc brakes, and it cross-references Monroe Shocks & Struts (e.g., 5851026000, 5911026000) for the same application. The aluminum body, integrated reservoir, and OE-based testing process support a precise replacement for the original hydraulic unit.
