Storing brake calipers &/or MC

Post by cgranju » Mon May 14, 2018 11:02 pm

I've read some philosophical debates & some good arguments on ways to store brake components without corrosion issues. In my experience, I have usually either transferred parts from one sealed system to another or rebuilt/overhauled ones from storage. I am curious if anyone here has experience storing (used) brake calipers (maybe even an MC) off the car in a way that will allow them to be used without hassle. I am figuring air (or humidity that is) is the issue...vac seal? Wrap/ziplock?

Basically, I have what I believe will be a nice donor brake set up (in a functional, sealed system) for my basket case 124 Coupe that I could transfer from the donor car to the Coupe but it's not ready/logistics/etc so I became curious if storage for about a year is viable.

Nope, just put them on my brake parts shelf in the basement without any protection. They can sit there for years without any visible degradation.

I've flushed them out with kerosene before, drained, and then left on the shelf.

--If the used ones are crusty/corroded when you get them, just remove the old brake hoses, open/remove the bleeder screw and drop them into used engine oil. They can remain there for years, and when you are ready to refurbish them, the task will be much easier. You particularly want to avoid corrosion on the piston/bore. For rear calipers, you can remove the rubber dust boot first.

I believe these are good, not particularly crusty, basically what you would expect on a reasonably maintained car. If my timing were a little better I would simply transfer them immediately from the donor to the other car but really they would get in my way at the moment.

Sounds like a variety of options here as well. Maybe combining kerosene bath with oil dip is good...basically I would like to be able to pull them out of storage clean them and use them rather than cleanup corrosion from brake fluid which may or may not be an issue.

Thanks! I figure this may be a question others can benefit from as well

for small items, I will spray them with WD-40 or something similar and seal them in a zip-lock bag. For big items like cam shafts, I coat them and use stretch wrap.

I rebuilt sone brake calipers for later use and put them in some ziplock baggies and as every manual says lubricate with brake fluid. Well when I decided to use , they had turned crusty and had to tear them apart again. I realize most people don't have access to industrial products but I always use Dow Corning silicone valve and O-ring lubricant to lube brake seals and it seems to work better long term. DOT3 Brake fluid won't dissolve it but silicone based brake fluid might.
