Detailed Description

The NM55492 brake master cylinder is engineered for Hyundai Elantra applications that use front disc brakes, including 2011-2016 model years. As the primary hydraulic component in the braking system, it converts pedal force into brake fluid pressure for the front and rear circuits. The aluminum housing helps keep the unit lightweight while maintaining the dimensional accuracy needed for proper brake system operation. This part cross-references OE numbers 585103X400 and 585103X500 for the same application.

Common Issues It May Solve

• Low or inconsistent brake pedal feel
• Brake fluid leakage at the master cylinder
• Internal hydraulic bypass causing pedal drop
• Uneven or delayed brake response
• Need for replacement during brake system service

Installation Notes and Tips

Before installation, verify the vehicle is a 2011-2016 Hyundai Elantra with front disc brakes and confirm the bore size and mounting pattern match the original unit. Bench bleed the master cylinder before connecting brake lines, and use DOT 3 or DOT 4 fluid as specified. Because the reservoir, cap, push rod, brake booster, and mounting hardware are not included, reuse or source those components as needed for the application.
