Can the stock master cylinder be disassembled and powdercoated? Bike is a M11000.
thanks
Probably, but you won't find any replacement parts, like seals, if something goes wrong during dis/reassembly.

+1, i have the goldlines on my S2R1k, and ive wanted to PC them black, but i cant find a rebuild kit. THats why i wont PC my brake calipers either. You can spray paint it with an enamel, it will be pretty strong, but not PC strong.
Thanks for the info guys.
No rebuild kits? Really? What, do you just toss 'em when they go bad?
Yea, you buy new ones... Brembo maintains that for safety reasons, they don't want "unqualified" individuals rebuilding their stuff, so they just up and stopped making rebuild kits.. Now you just have to fork over $400 for new calipers...

thats what i heard too. i couldnt confirm this, but the lack of rebuild kits makes this pretty plausible. im pretty sure you could open it up and figure out wht parts you need...but honestly you really want to sacrafice your braking power (and life) to turn your gold lines black?
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.

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.
Sad. Rebuilding brakes is not rocket science and can be very economical if you do it yourself. I hate our throw away society.

This happens with many different parts, not just brakes. My personal opinion? There is a lot more profit in a $400 brake set than a $25 kit. But what do I know? I'm a diehard cynic anyway.
If I'm not mistaken, this has been done for some time with valve seats. Instead of resurfacing them, they are replaces. And when was the last time modern cylinders were bored out instead of replaced. I don't think the Nikelsil linings allow for it.

There are vendors that will bore you cylinders and then Nikelsil plate them for you. Vendors like Calcycle works sell big bore pistons and then it is up to you to have your cylinders bored.
When I was younger and rebuilding VW bugs the master cylinder rebuild kit was about $15, the master cylinder was $35. No-brainer there but at least it was my option. But $25 vs. $400 would make me a lot more willing to take it apart. For Nikelsil cylinders, that's new technology. it amy take a while for things to catch up. A cast master cylinder is nothing special and the kit is basically a few o-rings and maybe a hone. Maybe I'm just a cranky old fart.

+1 for us cranky old farts.

Thanks, it is great to be acknowledged once and a while for who you really are. [clap] [clap]

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
