Any advice on how best to store a new set of brake master and wheel cylinders to prevent internal corrosion. It may be a year or two before I install them on a project car. They're still in original packaging and will be kept in a dry, heated garage. Thanks for any thoughts!
I stored my brake parts for quite a bit longer in the bottom drawer of my toolbox with no issues. If you control the humidity you should have no issues. I save all those little packets that come with electronics etc and throw them in my tool boxes.
Clean and paint the steel, wrap them in oily rags, try to keep stable temperature. Really though, consider they sit in a warehouse or parts shelf for possibly years, with no regard to temperature, just the cardboard box and maybe some port plugs to protect them.
Parts like that I keep inside the house in a broom closet or my pantry. I have made a list I tape to the inside of the door in case CRS kicks in.
I have a spare master that's oily and in a plastic bag. Still nice 2 years later. Temps swings in the shop over winter go as low as 40, high as 68 and in Mich besides. Yup, still oily.
Do you have access to a food saver type vacuum sealer? That should take care of any condensation issue.
You can buy a 30 pack of the small desiccant pack on Amazon for 10 bucks as I recall. I looked awhile back to store a block. Price may have changed.
What does the original packaging consist of? Are they sealed in plastic, just sitting in a cardboard box, or what?
It depends on how they were assembled, either with brake assembly lube or brake fluid. The brake fluid will of course draw moisture from the air leading to corrosion. Usually (hopefully), the assembled part is enclosed in a plastic bag. TECH ARTICLE - http://www.nbsbrakesupplies.com.au/technical-information/why-you-need-to-use-assembly-fluids.html
You're good. I've sprayed a squirt of Kroil in the bleeder screw at times. Still looked good 10 years later. No leaks
