Hi guys,

I will shortly be removing my Cup 1 for a refurbishment and thought I would take the time to give my brake calipers some love. They are peeling and look tatty after years of use photos for reference.

My question is how best to attack this as a DIY job without removing the calipers? Can anybody recommend me a process and the products that I will need? I have found a source for some replacement decals once they are painted.

Thanks!
Tim

I did the callipers a couple of years ago and they are still looking great. Steps, from what I remember, were:
1. Remove pads (I did this at the same time I replaced the pads).
2. Clean and clean with brake cleaner.
3. Sand off the “Porsche” and make sure the surface is flush.
4. Sand and sand and sand every nook and cranny. Finish with at least 1500 grit. You don’t need to go to bare metal.
5. Clean again with brake cleaner.
6. Mask everything around the callipers. Disk, hub, inner and outer arch.
7. I used a self etch primer (a couple of coats) left it a day.
8. I gave the calipers a very light wet sand (1500 or 2000) and then 3 coats of Dulux Dupli Colour Caliper paint.
9. I let that dry for a couple of days and then applied the new Porsche decals.
10. About a week later I applied a clear coat.

Make sure you wait a week to apply the clear coat or the colour paint will wrinkle …. ask me how I know…😞.

All up this is very easy but like with all painting, it’s the surface prep and now rushing it that makes the difference.

A simpler process is to use something brush-on like G2 Brake Caliper enamel. It's not quite as good as a primer-base-clear with sanding but it is a lot faster and you don't really need to mask anything off.
You can buy new PORSCHE stickers on ebay.

Alternatively, send the brakes out to somewhere like PMB and they'll come back perfect (a month and $1000 later...)

Oem calipers are anodized black and clear coated.
If you sand off the black you will have raw aluminum underneath. So if it were me, I'd use paint stripper to strip the clear coat. Light sand to even out the surface, and then degrease, prime and paint with good caliper paint.

Wont be as durable as powder coating but works well and you have less issue later with corrosion.

Thanks so much for the advice - going to take this route as sounds simpler and less messy than spray on caliper paint!

Thanks for sharing your process - really appreciate the insight!
