See June 2012 thread: I'm going rusty post #7
I use POR15 as it "stops rust permanently"
On the REAR brake discs:
1) Remove loose rust and 'clean' the painted surface with fine wire wool (a Brillo pad will do)
2) Paint the surface with POR15 (I used the Grey colour)
3) Allow to dry and overcoat with POR15 'Clear' - cosmetic only.
On the FRONT brake discs:
1) Lightly 'clean' the surface with fine wire wool (a Brillo pad will do)
2) Paint the surface with POR15 'Clear'.
Now others will have an alternative solution, but this is how mine were done 15-months ago and remain as shownâ¦
PS: How went the delivery Marcus?
Thanks John, detailed and thorough description as ever! Delivery, any day now...
Excuse my ignorance but if indeed the discs are to be replaced with this fix, will the hubs be changed too, i.e. are they a unit or separate? I don't want to spend time and money cleaning/painting needlessly.
On another note, having driven a Q7 around for 24 hours, I am loving having the RS3 back - so much power, such a solid drive and now that the exhaust mount problem is fixed the myriad of little irritating squeaks/rattles have gone away. Happy days!
