Anything I can do to prevent it? I got a bunch of orange splotches on my brake discs. I heard you can buy brake discs that doesn't cause brake dust.

 

i have an island made out of jello....would you like to buy that???
lol im just messin with you

buttt those discs are probably alumnium but the best ones are always going to rust, the type of metal always rusts....chemical rxn

 

All rotors tend to do that here is a thread already discussing this:

Move out of Seattle ....

damn Seattle Rain Festival

who took away the sun!!!!

 

Cast Iron + Water + Heat = Rust

Cast Iron + Water + Salt + Heat = Lots of rust

Short of moving somewhere without oxygen there's nothing you can do....

No brake discs are ever made of aluminum. Aluminum is just way too porous to withstand the stresses a rotor has to bear with.

For the very large majority of production cars, they are made out of cast iron... and they will always rust, no matter what.

 

True, most decent rotors are made from cast iron or some steel alloy and they all rust. If I let any of my disc brake cars sit for a few days, a thin layer of rust starts to build. First time or two that you apply the brakes, the pads will clean the rust off again.

If the rust bothers you that much, you could invest in a set of carbon rotors that will never rust. Some of the new high end Ferrari's and Porsches and such offer carbon brake rotor options. If you can find a deal, you may slide in under the $10,000 for a set of four.

 

Pity you can't make them out of stainless steel, but I'm sure there is some reason or other (heat resistance or somesuch).

 

Cast iron is cheap, very strong if cast correctly and easy to machine.

Stainless, depending on the alloy can't be cast so you'd end up literally having to machine the whole rotor from a solid block. You'd even have to machine the venting in front rotors. That'd be very complicated and expensive. Stainless is also not easy to machine. Then there's the much greater tendency for stainless to warp.

But they would be pretty!

 

is that it? In that case let me get a box.
