Brake Caliper rust

Hey all,

Anyone else having this issue? I know it doesn't really have any affect on performance but it just look horrible. Is there any way to cover it with something, maybe a sticker or something?

You like turbos huh? Looks like a garage full of them.

I can't see the picture but I'm also in Houston, TX and have a little rust on my brake calipers too (both my 335/535i). A sticker may look kind of weird on your calipers IMO and I'm not sure if any stickers can handle 200+ degrees of heat?

You could sand them down and repaint them on your own pretty easily. I've never painted my calipers personally, but my brother did it to his RX-8 and they turned out very well. I'm sure there are plenty of DIY guides around the internet.

I am guessing you are talking about the hubs? If not upload a pic!

You could remove the components in question and have them blasted and powdercoated if it bothers you.

If you try to wire brush them with something like WD40 it will only come back.

The hats on the rotors are bad and that can be solved with aftermarket rotors. If you're talking about the calipers then you can either paint them or upgrade...it's not cheap but there's not much sexier than a BBK behind a nice set of wheels.

Pic wasn't working so I uploaded one from Google showing exactly what I mean.

That rusted piece is actually just the clip that holds the brake pads. You can either order new ones from BMW or sand and paint your current ones. I just painted mine when I painted my calipers with G2 caliper paint and they never rusted again.

Just take off the wheel, sand them down, mask everything off and get some black caliper paint, they will look better than OEM and no more rust!!

Just ordered some G2 paint myself, what grade sand paper did you need to get the paint to stick effectively?

Nothing too harsh. Maybe 120 grit. It came off pretty easily.
