Caliper coating

[Guest]

Anyone every coat a caliper that wasn't broken down? I want to do mine tomorrow and was wondering if I could get away without rebuilding them.

Re: Caliper coating

I would worry about the boots and or square cut seal in the caliper. As well as any fluid in the caliper coming out and ruining your day. I think it would be easier to pop it apart and do it. You can reuse the seal and boot if you take your time poping it apart. I have many times just to clean the gunk out with no problems. Anyway just my opinion. Let me know how it goes.

I agree with hjeades,think about the time lost you might acure if you do not take them apart and find out later that the seals are ruined.400 deg is not uncommon for brakes to get.Also making sure you don't get any of the fluid from the inside
of the caliper all over the place could be a chore.

Re: Caliper coating

I just shot a pair of Brembos fully assembled. No problems whatsoever. It was at the customer's insistance that I not disassemble them. The hi-temp neoprene compound they use in the calipers can easily take the cure heat. Just thoroughly flush all the fluid out with water, pre-bake to dry them out, then cap the fittings, mask, and shoot. Be sure to flush with clean brake fluid before putting them back in service to make sure there is no burned fluid residue or water left in them.

Re: Caliper coating

The red did bleed into them a little, which I should have known would happen because red is bad for that. I should have done a coat of clear on the front, applied the decal, then re-cleared the whole thing. The white wasn't as bright as it should have been, but the customer was very pleased anyway. Said you'd hardly see it behind the wheels anyway. Next time I'll do it correctly.

Re: Caliper coating

So those decals withstand the temp in the oven? Where would you buy decals like that or have them made? I didnt know you can do that!!!

Re: Caliper coating

I got them from Mike (2003z) the Kaliper King, and yes they hold up to the cure temp just fine. I've coated over vinyl decals many times. You do have to make sure there are NO air bubbles, because it will bubble through the powder during cure if there is any trapped underneath the decal.

Any tips for applying the vinyl so there are no air bubbles? Did that RAL brochure show up?

I just peel off the backing paper, work them down slowly and evenly from one edge to the other using a soft but flexible window-tinting squeegee to press them down as I go, although fingertip pressure works just as well. After the decal is fully applied, I go back over the top with a stiffer plastic straightedge to make sure they are stuck good, then peel off the protective cover sheet. If there are any bubbles at all, work them out with finger pressure and if that doesn't work, take the tip of a needle and poke a hole in the bubble. It will smooth right out with pressure then.

That brochure hasn't showed up yet, but mail does come by stagecoach here, and the weather's been tough on the horsies!

Re: Caliper coating

Maybe I missed it... but did you shoot a base coat or primer on those calipers? They look pretty smooth, was the surface rough at all?

They were blasted lightly after outgassing, then just coated with Bright Red and a topcoat of High Gloss Clear. (Both Periduim powders, from Diamond Vogel).

No issues with the pinhole, other than you might see it if you get sloppy and make it too big or too deep. When it heats up, it smooths out and all you might see is a tiny dot. An air bubble in your clear shows up WAY more.

Cool.

Maybe the delivery truck ran out of money for gas. You should contact the government and get him a stimulus check then he can get going again.

Re: Caliper coating

I guess I need it whenever it shows up! Sure nice we can count on our Gub-ment. It's only going to get worse too, I'm afraid.
