Detailed Product Information

MPA Electrical NM4311 is a brake master cylinder engineered for Ford F-350 Super Duty trucks equipped with front disc brakes. It is designed to restore hydraulic pressure at the brake pedal and support consistent braking response after master cylinder wear, internal seal leakage, or fluid bypass. The aluminum housing and plastic reservoir match common OE-style construction for this application, while the 1.5-inch bore diameter supports the specified brake system requirements. This part cross-references Ford DC3Z2140B for the same application.

Common Brake Issues Addressed

• Low or sinking brake pedal caused by internal master cylinder leakage
• Uneven or delayed hydraulic pressure transfer in the brake system
• Brake fluid loss at the master cylinder body or reservoir area
• Reduced braking response after wear in the original hydraulic unit
• Brake warning symptoms tied to master cylinder performance

Installation Notes and Tips

Before installation, verify the vehicle is a 2013-2016 Ford F-350 Super Duty with front disc brakes and confirm bore size and mounting hole layout match the original unit. Bench bleed the master cylinder before connecting brake lines, use clean DOT 3 fluid, and inspect the brake booster, lines, and fittings for contamination or wear. Mounting hardware, push rod, seals, and brake booster are not included.
