O-RING - BRAKE (Mitsubishi MB1901-78225)

A worn brake o-ring can lead to fluid leakage and reduced braking effectiveness. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB1901-78225. The o-ring functions as a static seal within a brake assembly, preventing fluid bypass between mating surfaces. A common failure consequence is gradual loss of brake pressure, which may compromise stopping ability. During routine brake service, the o-ring should be inspected for cracks or deformation. This item ships at approximately 0.004 pounds. Verify the serial number or application, then call (562) 693-7748.
