gb110430 Posted December 15, 2007 Report Share Posted December 15, 2007 just had a new car , fantastic alloys a week old, and noticed inside the alloys where the metal disc is it is starting to go yellow and looking like rust is forming. ive seen this on many new cars in forecourts but was hoping this would not happen to me... im sure many of you the same is happening or has happened. what can i do to reduce this, are there any products or will just a cloth and water do ??? cheers Link to comment Share on other sites More sharing options...
maersk Posted December 15, 2007 Report Share Posted December 15, 2007 Your brake disc will always rust. Indeed it will do it whilst you watch if the conditions are right! This is perfecly normal. The discs are cast from grey, cast iron and will easily oxidise to form a protective layer. The fist time you brake the thin rust layer is mechanically removed by the brake pads. If you are sufficiently anal about it drive around the block to shine up those discs ! Link to comment Share on other sites More sharing options...
gb110430 Posted December 15, 2007 Author Report Share Posted December 15, 2007 just noticed driving it for five min removed the rust, halfords are saying they have products to void rust from happening or is just a con??? ad the products dont work Link to comment Share on other sites More sharing options...
dogbucket Posted December 15, 2007 Report Share Posted December 15, 2007 I painted the hub with hammerite to stop it rusting, but there is nothing you can do to stop rust forming on the disk face itself. Do not put any products on the disk surface as it will most likely stop the brakes working and damage the pads! Link to comment Share on other sites More sharing options...
alera Posted December 15, 2007 Report Share Posted December 15, 2007 You cant really stop the hub rusting either unfortuantely. You can paint them though. Eeventually the heat and corrosion will mean the paint comes off. Hammerite sounds like a good idea. They even do a heat resistant spray thats meant fo ruse on cast iron firplaces which would probably work well. Link to comment Share on other sites More sharing options...
steelwind101 Posted December 15, 2007 Report Share Posted December 15, 2007 HAHA!! I have mentioned this so often, you a nice detailed car and of course rust all over the disc. I think if you have a truely special car you have those ceramic ones, they dont rust? Still for everyone else....you could take it for a short drive and break a few times then give the wheels a wipe. A short lived though. Geoff Link to comment Share on other sites More sharing options...
Pincher Posted December 15, 2007 Report Share Posted December 15, 2007 I find a nice smearing of Vaseline help to prevent them rusting That was a joke BTW! Link to comment Share on other sites More sharing options...

techieboy Posted December 15, 2007 Report Share Posted December 15, 2007 Or, you could get some of those zinc? treated EBC disks. They have a gold colour to them and don't rust (at least they didn't when they were fittted to my VX). I think somebody also produces black discs that don't rust either. But the cheapest solution, as suggested above, is to drive around the block a couple of times gently applying the brakes. Link to comment Share on other sites More sharing options...
Tarmac_Terrorist Posted December 16, 2007 Report Share Posted December 16, 2007 It's not so much the discs going orange that bothers me but when I use the brakes on a simple trip round the block, the orange dust is transfered to the wheels - probably not good for the wheels either!

mb Posted February 18, 2008 Report Share Posted February 18, 2008 I was more thinking of painting the carriers as they have all gone horribly rusty - does that help ? Link to comment Share on other sites More sharing options...
dogbucket Posted February 18, 2008 Report Share Posted February 18, 2008 I just took the wheels off and slapped silver smoothrite over the hub part of the disc. It was on one of the few warm days last summer so it dried quickly so wheels went back on after an hour or so. Still no rust 10k miles later. If you have new discs just degrease first to remove any shipping oil I would think. Link to comment Share on other sites More sharing options...
bpsmith Posted February 19, 2008 Report Share Posted February 19, 2008 We were both joking about being shocked at painting the discs themselves. Was tongue in cheek though as know what you meant fella! Link to comment Share on other sites More sharing options...
