REAR MASTER CYLINDER GASKET 42455-97 1998 HARLEY DAVIDSON ULTRACLASSIC FLHTCUI

This rear master cylinder gasket (OEM 42455-97) was removed from a 1998 Harley-Davidson Ultra Classic FLHTCUI and is an original Harley-Davidson part, not an aftermarket reproduction. This gasket is used in the rear brake master cylinder assembly and is critical for maintaining proper hydraulic pressure and preventing brake fluid leaks.

At Midwest Moto Parts, every component is carefully removed, inspected, and photographed before being listed. If you’re rebuilding or servicing the rear brake system on your Touring model, using the correct OEM gasket ensures proper fitment, sealing, and long-term reliability.
