Storing a hydaulic brake system.

[SteveD]

I've just scored a cheap spare rear brake mc/reservoir and lines. It came with the brake fluid still in it. It wasn't dirty.

I have drained all the fluid from the reservoir and do plan to pull it apart and inspect the bore etc, and clean it all up.

Once all clean and dry, is it prone to corrosion? It'd be stored dry in a box on a shelf in a garage.

I'd spray some anti corrosive on everything with a note to clean it when used. I'd wrap it airtight and keep out of the light.

I would rub some brake fluid on the rubber bits.
And store it air tight (ziplok?) with one of those packets of stuff that absorb moisture.
(But that's just me.)

Both techniques should work. I have some oily sheets of paper that are designed to prevent corrosion when packaged with metal parts, so I would use that, or, for longer, probably spray it with Boeshield (wax based - doesn't hurt rubber parts). But, that would require the cleaning note.
