Honda Clutch Master Cylinder - NSX, 1991-05 (M/T)

Genuine Honda Clutch Master Cylinder. Part 7 in diagram.

Resolves the problem of the master cylinder leaking causing the clutch not fully to disengage and brake fluid leaking into the interior (pull back the carpet and follow the rod that connects the clutch pedal to the cylinder to look for dampness). Typically replaced every 10 years depending on use. 

Consider replacing the reservoir, hose, and cap if older than 20 years.
