Harley-Davidson FXD Dyna Rear Master Cylinder (OEM 1991-05)

This is the early style master cylinder assembly, correct for use 1991-05.  In 2006, the reservoirs were slightly restyled. 

Dust boot is in very nice, soft condition, and the cylinder and spring are clean underneath. We drained a few ounces of clear fluid, then wiped it clean with no indication of any grit or residues. Piston plunges cleanly, and it produced good pressure in our bench tests. Cap.

A very nice, clean assembly.
