MPA Electrical NM55377 Brake Master Cylinder
Brake Master Cylinder for Subaru Front Disc Brake Applications
Restore consistent brake pedal feel with this MPA Electrical brake master cylinder, part number NM55377. It is a standard replacement for Subaru models equipped with front disc brakes, including Impreza, WRX, WRX STI, Forester, Legacy, and Outback applications.
Key Features
- Aluminum master cylinder body with plastic reservoir
- 0.9375 in. bore diameter for OE-style hydraulic performance
- Reservoir included with cap and gasket/seal included
- Uses DOT 3 brake fluid
- Two mounting holes with 0.340 in. mounting hole diameter
- New condition, standard replacement grade
- Brake booster, push rod, sensor, mounting bracket, and brake pressure switch not included
Product Details
MPA Electrical NM55377 is a brake master cylinder engineered to restore braking performance by matching OE specifications through tested manufacturing processes and strict quality protocols. The aluminum construction helps provide a durable hydraulic housing, while the included plastic reservoir, cap, and seal support a complete master cylinder service replacement. This part cross-references 26401-AG031 for the same application.
Compatible With Subaru front disc brake vehicles, this master cylinder is a direct-fit service part for 2008-2014 Subaru Impreza, 2012-2014 Subaru WRX, 2013-2014 Subaru WRX STI, 2009-2013 Subaru Forester, 2007-2009 Subaru Legacy, and 2005-2009 Subaru Outback. If you are replacing a leaking or worn Subaru brake master cylinder, NM55377 provides the hydraulic foundation needed for proper brake system operation.
Common Problems This Part Can Address
- Soft or spongy brake pedal feel
- Brake fluid leakage at the master cylinder
- Loss of hydraulic pressure in the brake system
- Internal seal wear causing inconsistent braking response
- Reduced braking performance on Subaru front disc brake models
Installation Notes and Tips
Confirm vehicle fitment by year, model, and front disc brake configuration before installation. Bench bleed the master cylinder before connecting brake lines, then bleed the full brake system with DOT 3 fluid after installation. Inspect the brake booster, lines, and fittings for wear or contamination during service, since related components can affect pedal feel and hydraulic performance.
Quality Assurance
MPA Electrical tests each master cylinder against OE specifications using proprietary processes and strict protocols to help ensure consistent braking performance out of the box. The NM55377 is a new standard replacement part built for Subaru brake service applications.
