Painting brake discs. 

They don't cost a lot - £100 an axle every 5 years @ 10,000 a year.  Really?

Yes really! The rust breaks off in chunks and can catch you unawares. Quite easily. It is not a cost issue, or an appearance issue, but a braking performance issue.

So yes, REALLY !

So you have found a paint which will happily sit on a metal surface and endure the massive heat fluctuations that a brake disc will sustain?

I'm not a very quick driver but even I know that the Omega standard discs, callipers and pads are pathetic for the weight of the car.  They get smoking hot on occasions (I live near the A4174, Avon Ring Road) Roundabout after roundabout.

I really want to be proven wrong (no doubt I will be) but a squirt of some manifold paint on the fins will make bugger all difference - How do you get deep inside the disc?  How are you applying this rather 'thick' paint?


Sorry, I can't see it.

I'm not bothered if you see it or not.

The paint on both the GM discs for the Vectra C and Mercedes discs are painted with a fine grey paint which does rub off the disc with brake cleaner and a bit of elbow grease, almost looks like primer

It is effectively that. It is calleda Dacromet coating and a lot of manufacturers use it when the brakes are going to be behind wheels with lots of spaces between the spokes. Ford were doing it about 15-20 years or so ago.

Dacromet contained "hexavalent chromium Cr6" so it was replaced by Geomet http://www.anochrome.com/wp-content/uploads/2012/01/NOF.pdf in 2007.

Does anyone know if it is available for DIY use? it looks ideal for prolonging the life of steel fasteners on old cars, motorbikes (& preserved railways?).

I'm using Hycote very high temperature paint: "superb adhesion to bare steel"  "temperature resistant up to 650C".  £5 for a 400ml can inc delivery.

I don't care much about the innards, discs rust from the edges to the contact surface in my experience and it is the contact surface rust that is the problem.

5yrs or 50K

I usually managed 2yrs or 20k, max. Admittedly, usually due to inside edge corrosion...

If paint stops the corrosion, I'm happy with that .  I guess any high temp paint, such as that designed for calipers, will withstand the abuse

Are you talking to yourself again Mr TB, or is that a real person your quoting?

I reckon some nice bright blue sparkly paint will look the business on either of TBs cars

Ah the old "found guilty pretend fuddelment"  line. I see
