Product Details
MPA Electrical NM52873 is engineered to restore braking performance by matching OE specifications through tested manufacturing processes and controlled inspection protocols. The 1.0625-inch bore size, aluminum housing, and included reservoir support consistent hydraulic pressure delivery for vehicles originally equipped with front disc brakes. This part number NM52873 is listed for Subaru Impreza, Subaru Baja, Subaru Legacy, Subaru Outback, Subaru Forester, and Saab 9-2X applications with front disc brakes.
This part cross-references Subaru OE numbers 26401AC190 and 26401AE03A for the same application.
What It Helps Fix
- Low or inconsistent brake pedal response
- Internal master cylinder fluid leakage
- Brake pedal sinking under steady pressure
- Uneven hydraulic pressure in the brake system
- Brake warning symptoms caused by master cylinder wear
Installation Notes and Tips
Verify bore size, mounting hole layout, and reservoir configuration before installation. This master cylinder uses two mounting holes and does not include mounting hardware, a push rod, or a brake booster. Use fresh DOT 3 brake fluid, bleed the hydraulic system thoroughly after installation, and confirm all seals are seated before returning the vehicle to service. Fitment includes 2002-2007 Subaru Impreza, 2005-2006 Saab 9-2X, 2003-2006 Subaru Baja, 1998-2004 Subaru Legacy, 2000-2004 Subaru Outback, and 1998-2002 Subaru Forester, all noted for front disc brakes.

MPA Electrical tests each brake master cylinder against OE specifications using proprietary processes and strict inspection protocols to support consistent braking performance out of the box.
