Master cylinder is pretty crusty but after glass beading it and honing the bore everything looks reusable. Sadly no one carries rebuild kits anymore so had to order online. The cover and bail were original and the cover was pretty rusty. After blasting and re-plating, I tried the yellow chromate kit I bought from caswell. Worked perfect but as you can see, the pitting is very visible.anyone know a way to fill pits so that it can be replated?
