Chrome calipers leaking
I got a set of chrome calipers and I can't get them to quit seeping. There's not a drip but they are wet. They are as tight as I can make them, I took the calipers apart to check the seals, they look good. I checked to make sure there was no grit or anything under the chrome that wasn't allowing it to seal properly but that looked good too. I even went ahead and replaced the seals since I was there and it's exactly the same. A friend of mine bought chromed stock calipers from a chromer on eBay and his do the same thing.
Has anyone seen or heard of this?

I heard from a guy on the tourng model section that said his chrome Brembos did the same thing. He went back to stock and got chrome covers. I think that's the way to go or make sure they mask off the mating surfaces when they chrome. I think the tolerances don't allow for extra thousandths in plating and that's what causes the leak. I just picked up a set of stock black ones, I'll try to find some covers and call it a wrap..

I have a set of chromed Brembo's from an e-Bay vendor and have no issues in the 10k miles since putting them on. Always make sure to replace the brass banjo bolt washer every time you remove it. I have seen these sweat fluid when reused. And be sure to tighten the banjo bolt to the proper TQ spec as well.

I got a set from ***** Shiney and have no issues. I tend to agree that the extra thickness from the chrome is probably causing your issue. It might have to be thinned out a little on the edges where the calipers seal together.

I had a similar problem with some rocker covers I had chromed, and leaked bad. I took a close look and the mating surfaces had a slight lip and drips. I cleaned them up carefully with fine mill file.

Like someone mentioned above, I also think your issue is with the mating surfaces of each halve. There is a good chance that a small amount of plating in one area is causing them to not fit flush. If possible try rubbing them on a lapping block.
