Charliefarlie:
the brake disc faces attract moisture and turn brown with surface rust through the winter months,
Has anyone any ideas if it’s possible to stop this ? Anything the swept areas can be treated with safely ?
Don’t treat the brake surface with anything!
However I’ve used wheel covers successfully after finding rusty discs a few years ago after a damp fortnight parked at Gatwick.
I posted here about the success of wheel covers
Success! After a cold, wet and windy couple of January weeks parked at Gatwick with the wheel covers in place, the discs were clean and shiny when I removed the covers. I’ll be using them again in March.
Compare this with seeing the discs skinning up with rust while still washing the car! (Which is easily fixed by a ten minute blow-dry and brake-polish on some nice quick local roads.)
EDIT. Here’s a picture.

The second link in the post above points to the covers I used.
Job done. Clean discs, new Brembo pads, and painted calipers fitted.
I reused the unmarked Mazda shims because the Brembo shims had a less good match to the contact points for piston and caliper.
The piston winder kit from Az had a 4pin adaptor to wind the piston, perfect. I was prepared for a struggle, but they were dead easy and smooth, with just a touch of brake fluid to lubricate the boot-to-piston seal of the bellows.
Robbie’s guide in the Downloads is excellent, torque settings very…
