Product Details
MPA Electrical M55128 is engineered to restore braking performance by replacing a worn or leaking master cylinder in the hydraulic brake system. The aluminum construction and 0.875-inch bore support OE-style brake pressure delivery, while the remanufactured design is tested against OE specifications using controlled inspection and validation processes. This part is a direct service replacement for 2001, 2002, 2003, 2004, and 2005 Honda Civic applications with front disc brakes.

What It Helps Fix
