i took my stock rotors off and i will proibably want to put them back on sum time in the future. but if i leave them out they will rust to ****. so would it be okay to leave them in oil or something to prevent rusting and clean them off when i need to use them again?

 

oh okay.. thanks

 

uhh no.. thats not what i ment, i just want to STORE it in oil, and i was wondering if that was okay. when i need to put them on again they will get flushed out and then cleaned/dryed and then put on. i wouldn't put the rotors back on with oil lol but i think i am gonna paint them so they don't rust

 

the PROBLEM with using oil to store them in is this.....your rotors are made of cast iron...as Jesse pointed out...and cast iron is POROUS....you will actually end up with some oil working its way into the grain of the metal over time....and you will NEVER get it all removed once you go back to use them again...and the oil will leach out of the cast iron when you heat up the brakes....and that is the LAST thing you want....oil getting onto the discs/pads when you are wanting to stop....BAD....so as Jesse suggested....get some cheep *** spray paint and give them a good coat....this will seal the surface and prevent them from rusting up ..... NOW....as far as the bearing surfaces go....I would just coat that area up with a good coat of grease.

 

OOPS...one more thing I forgot....do NOT store them leaning to one side....

either stack them up nice and neat on their sides with no side presure on the rotors themselves...or put a rope through the centers and hang them.....

gravity is NOT your friend...and yes....believe it or not...if you took a rotor and leaned it against something and left it with presure on the rotor itself for long enough....when you put it back on it woud be warped....sure as the world is round.

been there....done that....it WILL happen, given enough time.

 

thanks everyone, i will put it flat on its back with a good coat of rust paint

 

Sounds like rotors are made out of pretty crappy materials .. must be the most reasonable thing in terms of cost/performance though but this sounds like a damned lot of work just to store some metal discs!

 

NOPE...I ment JESSE....HE is the one that pointed out that the discs were/are made of CAST IRON.....lol I read just fine. :{D

seems YOU are the one having a problem with the old memeory! lol lol

:{D

rjakobs......no they are not made out of crappy materials....all stock production rotors are made of cast iron...they have been for ages.....but even quality parts when stored improperly will become damaged.

 

YES you did....my comment about "as jesse pointed out" was that HE stated that the rotors were made of cast iron....and THAT is why getting oil out/off of it is such a pain....the fact that cast iron is porous....that was what I added....and was explaining in more depth YOUR point of why OIL IS BAD....at least to store his rotors in.

 

Why not use WD40... Not an oil base lube, just a mild solvent that does not evaporate, rinses off easily with water and remainder will burn off easily. We use to coat freshly machined cylinder bores with it.

 

its a delicate process..
