Hi all

Being an active gaylord I have an MX5 MKIII that I use at the weekends (use a diesel golf for commute)

Anyway have noticed that the brake discs go rusty as heck whilst its sat on the drive. Ive decided not clean them and put wax on for obvious reasons.

Is there anything that can be done or is it nowt to worry about? The discs themselves were replaced fairly recently but at a recent (main dealer) service the "bloke" mentioned it. Mind you he also mentioned that the air conditioning was not blowing cold. Thats because it doesnt have air con.

Cheers all.

Nothing you can do. They all do that.

Disks will show surface rust in a matter of hours if you wet them, for instance when you wash the car and then don’t use it.

It cleans up the first time you take the car out.

Depends how long you leave it for. Using the car once a week or so should keep the discs clean enough - and you can paint the parts that aren't a friction surface to make them look less nasty if it's a concern. Or you can buy coated discs when replacing them.

Having the car sat outside long term unused can give you bad enough pitting that it's a issue, but there's not a lot to be done on that front, bare iron in the British climate is always going to get a bit crusty.

It's pretty common on cars that sit around for a bit. Normally a drive and some firm braking clears it off I believe.

I'll hold off with spraying them with WD40 when I get home then. wobble

BH make something called atom-mac that might be worth looking into (not affiliated just had good experience with a lot of their products).
