did you paint your master cylinder? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Just bought as new power brake setup and in less than 2 weeks some surface rust showed up on the master cylinder. Anyone paint there with lasting results? I am thinking of painting black.

Just painted mine with Eastwood Brake Gray. It's not cheap, one can with shipping ran about $24...But from the test they ran...brake fluid will not eat it. It actually has stainless steel particles in it, so the grey IMO, is somewhat of a misnomer. It comes out shinier than that. To me, it was worth it because I had my original master cylinder, prop valve, and calipers all rebuilt, and didn't want to see them get flashed over. So I sprayed them all, plus the rear wheel cylinders, the booster (also rebuilt/plated) /brake rod linkage.

I like the look, even though it's shinier than cast...If I have a chance, over the next couple days, I'll try and post a pic of how they turned out.

I used the rustoleum auto paint at Autozone - 500 degree and supposed to stand up to oil and grease better. I painted the MC with cast color then cleared it with the same type stuff. Cost about 14 bucks. It has been a little over two years and it has held up well. If you spill any brake fluid on it it wipes right off without stripping paint.

I used hi temp Cast Iron Gray.

I just used Eastwood Brake Grey and it's very light, like an aluminum intake manifold. For my tastes it should be darker. I like JWall's photo above, I'd go with the Dark Cast if I had to do it over.
