Painting brake disc edges

[adamnreeves]

I was wondering around Halfords today and brake caliper paint caught my eye. I was intending on getting some for my calipers (when I get them) but as was going to use the same paint to paint the rear disc centres and edges. All the caliper paint was bright vivid colours of course and I wanted black. So in wandered into the engine paint section. I sought the highest temperature black was described as V.H.T. (hand brushing type), the specification says upto 650C.

Now I have got home I have the destructions and they say to cure the paint you have to start the engine and bring upto to temperature. I am wondering if this paint is suitable.

Painted my disks with smooth hammerite and my engine/gearbox,all seems well so far.

you can use it and then put it in the current wifes oven.May kill the taste of food for many a night after tho'.As animal said,I have used smoothrite and seems fine,although nothing garish,just black

Ditto, use smooth hammerite. I've been using it on discs and calipers for years, never had a problem....

used high temp matt black spray paint [VHT] no problem on rear and front discs.no need to heat up. will do that when you next use them.

Is it too late to do this if the non-swept area of the discs are rusty?

My discs front discs I have not even ordered yet. My rear ones are still in the box! So no problem.

Problem is that the next time I use them, i.e. the first time, could be 18 months away!

No, but obviously you need to clean the rust off first...

I would not have though hammerite would be suitable for these temperatures. I guess the engine might reach a few hundred degrees and brakes higher than that I think?

Keep guessing...

I've not convinced that normal road driving gets westfield brakes particularly hot. I'll stand corrected of course, but my simple 'touch it quick to see if it's hot' tests after a drive have never shown the brakes to be more than warm to the touch.

Maybe I'm not driving it hard enough though

i normally spray the whole disc ,only lighty on the disc the brake pads soon burn it off but leaves paint on any where  that needs it from getting rusty.

if they already rusty just use a rotary wire brush in drill first.

The manifold will certainly see high temps, I guess I could apply a small patch of hammerite to one of the pipes under the bonnet to see how it bears up.
