Master Cylinder rebuild

[elisent]

Before I anodize my master cylinder I have a few questions. I removed the piston and there seems to be alot of corrosion. Does anyone know the diamater in MMs? By the looks of this I feel it needs to be sleeved. Any good sources? Thanks, Eli

13.7mm I think. Thats the OD of a socket that almost got stuck in mine. I think they can be honed slightly larger and still work. Sleeving it would be a trick to get the resivoir holes to work.
