I've taken the brake discs of my car and they are seriously rustly. So on my shopping list for minispares are new disc and black stuff pads (MSSK014). Now in the ultimate mission to rust proof everything I haven't seen anything on here about protecting the brake discs. It seems sad to think after rebuilding her, when everything else will still be shiny the brake discs will be rusting. So the question is can they be painted? OR be protected by some other means?

 

Obviously the paint would have to be extremely high temperature. EBC don't give a spec for the black stuff but the green stuff pads are designed up to 600^oC so as long as the paint can withstand that. And as long as the pad/disc interface isn't painted! The only negative I can think is the paints inefficiency at dissipating heat. But is it any worse then a layer of rust?

Silly, just leave them. Nobody is looking at your brake discs thinking 'Oh, they're rusty', in fact I doubt anybody is looking at your brake discs at all. It's unavoidable and anything on brake discs that wasn't supposed to be there is just a bad idea to me.

Brakes rust, period. They go through such extremes of heat cycles, different elements ie rain salt etc etc that its not worth the effort. And as Craig has said nobody looks at your discs unless its going through an MOT.

I paint mine, and it's hardly any effort at all. 

 

Besides, if you've spend hundreds on some nice shiny wheels and brake calipers, why not? 

 

 

It only takes a couple of minutes to whack a bit of VHT matt black on them! I mask up the mating faces, but the braking faces i don't bother. Obviously try not to layer the paint up there, but it will have worn off before you get to the end of the street!

Yes paint the hubs and the non pad contact area, but if you do get paint on the braking area clean it off with thinners as if it does get picked up on the pads it can impregnate the friction material and cause juddering, far easier to wipe it off.

Sweet sounds good. I'll add them to the paint list then :)
