The brake fluid had got onto my calipers and eaten away some of the lacquer. The questions-

I will have to remove all the lacquer off them, whats best to use? A wire brush?

What paint to use - Obviously it will need to be VHT and the same colour, can you buy the stuff from ARUK that comes on it?

Where can I get VHT clear lacquer?

I have seen some VHT lacquer paint in Motor World, reckon its worth a punt? I think not but dont know:confused:

P.s will lacquer the rear ones while I'm at dont know why they aint done as standard anyway (as you pointed out OA!)

you should be able to spray a clear coat over them..

Dont wire brush them as you will take off the red paint and the logo!!

This happened to my fwd callipers:( , I believe it is a kind of ultraviolet degradation not brake fluid as I also thought (although I doubt brake fluid would do them much good!) if it is UV degradation the lacquer will just peel off to show a mat red paint finish underneath. The best way I found to remove the lacquer without damaging the red coat or the alfa transfer is with a strong sticky tape used like a waxing strip (sounds odd I know!) this will just remove the damaged lacquer. Then all you need to do is give them a good clean and degrease mask it off and give it several coats of any good high temp gloss lacquer. And hay presto they look like they just left the factory! :D

I personably would not bother to go to the trouble of powder coating the callipers (they will need to be removed from the car and completely stripped for this to be done properly) unless they are so chipped/corroded they require refurbishing anyway.

Any good independent motor parts shop should stock high temp paints and lacquers, I would avoid halfords as they will be double the cost.

P.S. found ebay linky:D

Interesting comment about the UV.

If you look at the calipers though most of this degradation is leaking from the bleed nipple.

Ggood tips for repair though! :cool: :thumbs: :)

This is only were the lacquer has visibly separated from the red painted surface leaving that ugly milky look (possibly weakened by brake fluid leaking from the bleed nipple). However when using my waxing technique ;) (with sticky tape!) I found that the lacquer came off fairly easily on the entire outward (direct sunlight) facing half of the calliper, even though it did not appear to be separated/milky and was not likely to have got brake fluid on it. This backs up the theory that the factory finish of the calliper has suffered a chemical decomposition due to UV light.:D

I highly recommend the Foliatec range of Calliper paints. Not only does the paint seem high quality but is also supplied with a seperate lacquer, so there is a chance you can re lacquer the original paint.

I think the kits are around the £25 mark.

Well, the paint on my front callipers was until recently in great nick (just a couple of stone chips). I had done nothing special to them, just cleaned then as much as possible through the wheels when washing and at least once a year had the wheels off for a clean/polish.

Then this summer at a well known Alfa specialist they allowed the fluid to run over the calliper so below the bleed nipple there is a lot of damage to the laquer :mad: The paint seems fine underneath so presumably I can sort it as and when I have the time. But it's still a PITA - even Alfa main dealers had managed to change the fluid with no problems before...

When challenged they said it was because I was using aggressive race fluid, but a friend had his done (standard fluid) at the same place with the same result so I reckon they are just a bit sloppy with the fluid changes...

The lacquer on my calipers has started to go around the holes where the pins of the pads go into. The previous ones had stuck so had to be punched out and this split the lacquer. They were perfect up until this point.:(
