so it comes to that time when blingy stuff happens and my brakes are due for a rebuild.... i have new disks and pads sitting in my room and was wondering what paint to use on the disks to simply keep the rust off...
ive seen it where the whole disk is painted and after some use its happy etc...
and then the calipers ill rebuild at the same time and paint them...
the simple question is which paint is best to use?
halfrauds high temp paint?
preferably a rattle can of sorts!
thanks chaps

never had a problem using hammerite (smooth) on calipers, not sure about painting the disc though, a coating of wd40 or similar will keep the rust off - just remember to degrease them before use.

I used satin black engine enamel when I rebuilt the brake calipers on my saab. They havent gone rusty yet! I did give the outside of the caliper a good go over with the angle grinder+wire wheel before painting.

i see, just thought they get hot but not hot enough to poop the paint during road use i guess...
i may just use some plack on the disks to just keep the rust at bay

if you're keeping the disks inside, unless you're not planning on fitting them for fifty years, then they'll rust less than a set on a car thats been parked up for a weekend in wet weather.

I'm taking it that he wants to paint the hub of the disc rather than the bit the pads act on cause I cant see any reason for painting that

I use smooth Hammerite, works great. High temp paint might work better on the disc centres, I am guessing you're wanting to paint the centre of the disc and not the part the pads are in contact with..

Well to avoid any rusting on the disk i used wheel silver on the entire disk not concentrating on the contact area
So the outer lip is painted too, but i want it so that theres a good line where the pads go!
So my question is will it be ok to let the pads remove the paint when bedding in so i get the crisp line or scrape the worst off?

You might gum the pads up a bit (depending on how much overspray is on the contact area)
It'll probably not cause a major problem, but personally I'd just remove as much as you can, either by wiping it off with thinners or some 320 ish sandpaper.

IMO i wouldnt have painted the disks on the contact area at all, But i cant see there being an major problems in letteing the pads do the work to remove as it wont have adhered properly in the first place. I have had a car stood for almost 2 years with only wd40 on to prevent rust and after a couple of miles they were gleeming.

Ah yeah as there small disks a bit but ill get some thinners on there and paper to remove the worst! But I'm leaving it to cure as long as possible to make the paint more flakey so it shouldnt gum up too bad!

Just take all the paint off.  I don't understand why you'd be worried about the very edge of the brake discs going rusty - most of it will be covered by the calipers and splash plates, and the centres of the brake discs (the ONLY bit I would even consider going near with paint) is covered by the wheel. In my opinion (and I'm employing a little common sense here): Painting calipers: Fine. Painting brake discs: Not fine. Dangerous. |

But you only see the very edges of the brake discs when you remove the wheel. Any part of the brake disc visible through the holes in the wheels when fitted is a friction surface and so needs to be free of any contaminants - grease, oil, brake fluid, paint - as it affects braking efficiency and is thus dangerous. That's why when you fit new discs you have to clean the oily coating off (the coating which stops the discs going rusty), as otherwise the contaminants will get burned into your brake pads and affect their performance.
If you're worried about the friction surfaces going rusty then just drive your car more, the braking will polish them up just great.

If you want pretty brake disc centres...  I guess it would be ok to paint the discs if you completely cleared the contact area before use. The paint could clog or even contaminate the pad material. |
