Re: IML: rust on master cylinder

["Frederick Joslin" <fljoslin@xxxxxxxx>]

My concern is about the effects of spilled brake fluid. It seems to be very good at removing paint and then as you say you get rust.

Has anyone tried one of the phosphate treatments for this application?

Also, to be the devil's advocate, these master cylinders were designed to rust in the OEM application so should anything really be done to prevent that?

 

Thanks all.

I am going to replace the master cylinder on my 69 Lebaron and would like to know if there are any suggestions for a "home" method to stop the new one from rusting.

On the last master cylinder I replaced, I decided to try some spray paint that I found at a local auto parts store (can't remember which store, but it was likely either AutoZone, Advance, or NAPA).

The paint is Plasti-Kote Rebuilder's Finish: http://www.plastikote.com/plastikote/auto/template.jsp?searchcode=RES&product=Rebuilder

All in all, it did OK, but not fantastic.  It has prevented the master cylinder from rusting, but it does not resist brake fluid.  If brake fluid spills on the paint, the paint will come off in that area (and then, of course, that spot rusts).

But it was relatively cheap, and as long as you're careful checking the brake fluid, it works fine.  I also found that if brake fluid does spill on it, if it's cleaned up quickly, it won't hurt the paint.

Hope this helps!
