Hi all I have a 95 classic 3.9 V8 which travels abroad each year and has just come back from Hungary, fully loaded roof box canoe etc and she performs great, however this year I noticed the rear discs not nice and shiny like the front, is this normal? they are not rusty but not shiny as the front. apart from a rolling road is there a simple way to check. I have seen the service kits available which I don't mind doing but if its normal I wont bother. I did replace pads and rear springs earlier this year. Any suggestions?
