Product Details

MPA Electrical NM4316 is engineered to restore braking performance by replacing a worn or leaking master cylinder with a new hydraulic unit. The manufacturer validates each unit against OE specifications using sample-based testing and controlled inspection processes, helping deliver consistent brake pedal feel and hydraulic operation right out of the box. This part cross-references 68263298AA for the same application.

Compatible with 2016-2023 Fiat 500X, new with front disc brakes, and 2015-2023 Jeep Renegade, new with front disc brakes. Search terms such as Fiat 500X brake master cylinder replacement, Jeep Renegade master cylinder for front disc brakes, and NM4316 brake hydraulic repair all point to this application.

What It Helps Fix

• Soft or inconsistent brake pedal feel
• Internal hydraulic leakage in the master cylinder
• Brake fluid loss at the master cylinder body or seals
• Reduced braking response from a worn hydraulic unit
• Brake warning symptoms related to master cylinder wear

Installation Notes and Quality Assurance

Before installation, confirm the vehicle is equipped with front disc brakes and verify bore, mounting, and hydraulic connections against the original part. Bench bleeding is recommended before final installation to reduce trapped air in the system. Use DOT 4 brake fluid only, and transfer any required components from the original setup if applicable, since the reservoir, booster, push rod, sensor, and pressure switch are not included.

MPA Electrical manufactures this master cylinder as a new standard replacement part and tests it to OE specifications using proprietary inspection protocols and OE sample references for consistent hydraulic performance.
