Rusted Brakes, what to do?

[jaackyy]

Hey all,

I've been wanting to paint my calipers lately, but jsut the other day, I've noticed that there
is a **** load of rust all over my rear brakes.

Google search tells me this is normal, and comes off when you apply brakes, however that does not seem to be the case for me and I definately want to remove this as it's quite an eye-sore.

It's a bit late, so I'll update with actual photos tomorrow, but for now, it's something similar to this:

Thanks for help, will update tomorrow

TL;DR
Brake discs are rusty, how to restore to normal/maintain it?


**EDIT: ADDED PHOTOS**

You'll probably need to get the rotors machined or polished mate

That's annoying... Since I Recently purchased the car, and the RWC included having the rear brakes changed, I have a warranty on the check, would I be able to claim warranty on this?

Mine will do that overnight... It goes away when you drive the car, right?

The rust is because of the material the rotors are made of... No big deal

Go for a drive put brakes on Problem solved. Dont take it out in the rain or wash it and it wont happen again. Mine go like that when I wash it.

Brake harder

Just added photos to main post.

I took it for a quick drive and did some braking but its still there, albeit maybe a little less.

can i take a microfibre cloth or something and try rub it with water or something?

You worry too much go for a longer drive with more corners needing a bit more braking Every time they get wet they will do that.

The rusty part appears to be the hub, not the friction face of the rotor itself. You can wire brush the rust off & paint it at the same time you do your calipers

So it's safe to paint that bit where the rust is? I don't wanna paint it and make my brakes not work properly or something

Yes the pads dont rub there do they Use the same high temp paint as you do the calipers with You were going to do that werent you

In this photo - the black bit you can paint. The shiny dinner plate part with the slots has to stay shiny. (your's doesn't have slots)

Search brake rotor painting and brake caliper painting. There are heaps of you tube how-to's out there

In the picture that was added later, yes. The originally linked pic only showed the rotor face.

Even if you painted the rotor faces, I couldn't see the paint there surviving more than a second of braking. Of course you could have an accident in that period...

I've seen people paint the friction face & rely on the brakes to remove the excess. It works but is also can contaminate the pads & smoke like crazy until it burns off.

So at least make a token attempt at masking the friction surface.

I made this dodgy cardboard screen when I did my Subaru



There was overspray but i wiped most of it off with metho.


And it does look better

Alright, thanks for the help everyone !
Last quick question, since google is giving me both answers.

When painting my calipers, do I need to prime them? Or can i just wire brush them, degrease them, dry and then spray?

One of my friends says he just cleaned them up, got the caliper paint, sprayed it into a container and painted it on with a brush. They're still going strong 1 year later too.
