Brake Discs ……..
Discussion
…. I have my (to me) exotic road car and it's really just foe high days and holidays. It has sat outside without turning a wheel, for 5 weeks.
The brake discs are covered in rust - ok so they clean off after the car is driven for a bit, but the rust and corrosion sticks to the alloy wheels and the nice shiny and just painted callipers ……..
Here's my question - are Brake Discs available in stainless steel?
[edit] - to read Brake Discs, not Callipers!

ker. OP, depends on the overall design of the discs but it's quite possible to have a set of stainless discs turned on a lathe to suit. Youred likely be starting with a lump of billet stainless which won't be cheap but will still be very much cheaper than CC discs. Combined with low dust pads it would be a huge improvement. I can see the attraction of SS discs, there's nothing worse than seeing rusty dics behind a nice set of alloys..

He could but stainless steel discs have a lower coefficiency compared with cast iron. The SS discs may not like the heat cycle so much either. flashbang said:

Ordinary brake discs are usually cast iron, which has friction, thermal expansion and wear properties well suited to this use. They are vulnerable to fatigue failure if overheated, so you might find people using steel disks in highly stressed applications. I don't think anyone would use stainless steel since it is relatively brittle, has a high thermal expansion and poor conductivity which all make it more vulnerable to fatigue failures as well as having a lower friction coefficient.
I suppose that being rust free might be more important for a show car but it isn't a good choice for a car that will be driven.

I’ve seen gold plated discs on a show car many years ago. Was never driven, just trailered and towed into position.I suppose that being rust free might be more important for a show car but it isn't a good choice for a car that will be driven.
Two piece discs with aluminium Bells are an option. Stainless steel wear face would be two hard and just polish up. Cast iron is relatively soft and sticky hence it’s used for brake discs. Electro magnetic brakes would probably be best for zero rust and dust.
You could get the wheels ceramic coated, which would help stop the discarded friction material sticking to the wheels, making them easier to clean off.
Not sure if you can apply it to calipers with the temperatures they get to, but worth asking.
Failing that regular application of a hard wax, the stuff you get in tins not bottles will help with cleaning the dust off.
