Rust prevention/Painting of brake disks

[greg]

Hi Guys,

I have Brembos on my Ibiza and it really annoys me how much bare metal (non braking) is exposed on the disk, which instantly rusts up!! I tried spraying the surfaces with heat resistant silver exhaust paint but the rust has started to come through that too.

Has anyone got a better method for preventing rust on the exposed metal parts of the disk?

I was thinking using this zinc rich spray to prevent the rust from returning and then paint over with the silver exhaust paint.....

any views on this?

Cheers,
Greg

I wouldnt personally touch the braking part of my disk brakes, but if you are serious then maybe ebay 'acid etch primer' will stick to the surface better once you have cleaned up the rust thats on there and then paint... good luck

you're an idiot if you want to risck contaminating your braking surface to make it look cool! leave it alone!

my view = silly.

Leave them well alon mate. they are the way they are to make you stop, painting them will stop them doing that as well.

I Think your missing what he is trying to say... He doesn't want to paint the disk... He wants to paint the inner part of the disk that doesn't touch the pads hence the bit that looks rusty on the inside.... I used normal black heat resistant paint on mine... worked a treat..

Im Not going anywhere near the braking surface of the disk!!! read the original post. The car would have to be left unused for a while for that to start rusting and after a few drives the action of the pads would get rid of any rust!.

Its only the bare metal 'hub' section of the disk that i intend to paint, the surface that is perpendicular to the braking surface. On the brembos this is massive and rusts quickly which is unsightly. There is no way painting this would effect the braking efficiency.

Thanks for the responses but probably best to read the post properley before chucking insults about

Daz, How long ago did you spray the disks? And are there any signs of the rust returning? I did mine about 6 months ago and its already starting to come through again.

you need to clean off any rust the best you can wire brush etc...its no good just painting over rust it WILL just keep coming back...

I cleaned the disk up with a wire brush attachment on a power drill before i sprayed them last time until there wereno signs of rust at all prior to applying the paint...... bt the rust came back

Zinc coating works well, spray the whole lot and it'll come off the disc where braking is applied very quick.

Inconel would do the trick,

specialists stuff but some engineering company might do it for you.

Must be getting on for nearly a year now and no signs of any rust coming through...

I just used Hammerite, it's heat resistant and can be applied on top of rust.

Or get some two piece discs with ali bells, job done

thats what I would use too. but as said get a wire brush over the rust and job done. Might aswell do the hub part as well, as I hate to sight of the corrosion through the rim (still have to do mine though )

 

[CupraElliott]

I used a wire wheel on a grinder to clean them up first.

Also done any bare metal I could see whilst I was there.

If your like me and you hate looking at rust everytime you take the wheel off I would do this. Not much effort, no masking and only take a few hours.

the fronts on mine are ok its the rears that are s**t car was sitting for a week whilst i wasnt using it and the whole disc had rust on it was making well imbarising noise when i had to drive it next..lol..squeeks to hell anyway if im in traffic and breaking lightly ok if im breaking more hard though..??

 

[greg]

Thanks for all the replys guys

Might give hammerite a try i reckon, did you all just use the standard spraypaint or get one of the heat resistant variants?

I prefer the brush on stuff for jobs like this, saves the masking up. Leaves a very nice finish, almost a sprayed on effect. It's the formulas in the paint that cover up all the brush marks, 'rollable' formula or something.

I just went to BnQ and bought a big pot of normal gloss black Hammerite paint.
