That's fine, but I think the kits are gone because Brembo wants to cut the liability. I can see a shop not being able to compete with the price of a new unit, but I can do a lot of work for $100.

This is happening pretty much industry wide.  Rebuilding a coffin master that can be bought new for not much more than $100 is no longer cost effective for a shop at today's labor rates so there is reduced demand.  Then add liability to the mix, by by kits.

Brembo, or US distributors who prefer to remain nameless?  AFAIK, TAW has rebuild kits.  They had them last fall when I ordered a set of pins and clips that every other distributor told me was backordered for some mysterious reason.  I know they had them because I spoke in detail about rebuild a set of calipers that I bought that was allegedly leaking.  They don't, so I haven't pursued it.

Edit:  Woops, just double checked with TAW and they no longer have the rebuild kits.


And fwiw, what is the curing temp for PC?  AFAIK, brake seals are good to 600Ëš, I don't see why you couldn't just pull off the outer rubber seal (carefully) mask the pistons and powder coat.

Secondly, Eastwoods sells hi-temp paint that would work for painting brake calipers as well.  It needs to be cured in an oven, but at temps that calipers can handle easily.

Someday, I'm going to do mine in Red.  Probably powder coat.

Is 600 degrees intermittent or sustained? And how solid is that information. I didnt think they would last 400 degrees. I thought all the seals were synthetic rubber or some type of plastic.

Either way, were talking about the Master cylinder, not the caliper.

Personally speaking though, i'd wouldnt PC brake calipers for anyone unless you broke it down for me, so if you mess up on the rebuild its on you, and not me.

But as far as curing goes. Its going to be in the oven for atleat 15-20minutes at 350-450 degrees depending on the type of powder your using. Most of that time is spent heating the metal to that temp so the smaller the item is, the faster it heats up, but you dont want it to heat up too fast. The temps also go as low as 275 on some powders. The low gloss powders typically need a higher cure temp than the high gloss powders (most low gloss is epoxy, and high glosses are TGIC powders) of course you can get epoxy in high gloss and TGIC in low gloss, but it isnt easy.

I don't think I'd risk just "baking" the hole mc. Sounds a little risky to me, and a have really bad luck so I try not to tempt fate. :P
