I think if the clear is gone you'll probably need to redo the paint on them.

 

I just did this project yesterday and wrote a very detailed how to guide with lots of pictures to hopefully make this easier for the next guy. It goes over rebuilding the calipers as well as painting them. Check it out here on DirtyEvo; I hope this helps! Rebuilding and Repainting Brembo Calipers - DirtyEvo.com

 

you honestly don't need to disassemble them. On my last evo I just painted them off the car and taped up the boots/what not really well. They came out good. I painted them black and got the brembo logos to put back on them. You don't have to powdercoat them if you don't want to. Powdercoating is just a more durable finish. the pic below is of mine painted. They turned out just fine. You do need to sand that clear off if you are just going to paint em though.

 

I see all of the responses about not splitting the calipers. Well I just discovered that mine have been previously split and reassembled incorrectly (instead of both bleeder valves being up, one half is up and the other is down). I have no choice but to take them apart and put them together correctly. Any tips? Has anyone successfully done it?

 

Are you certain someone didn't install them on the wrong side? The brake line that connects the halves hydraulically is on the bottom and the bleeder is on top like you said. You have to flip the caliper to move it to the other side putting the bleeder down if this happened. I don't think its possible to assemble them backwards, but I may be wrong.

 

No, they were assembled incorrectly. I bought them used. The rears don't have that external crossover pipe like the fronts do, it's inside the rear calipers. Both bleeder valves should be towards the top. On mine the outsides on each side were towards the top while the inside valves were towards the bottom. This was preventing the internal hydronic crossover from lining up and not allowing any fluid to reach the outside of the calipers at all. I had to split the halves, swap the two inside halves, and reinstall. Now they bleed perfectly.

It was actually a very easy job. If anyone decides to do it, even though Brembo recommends against it, you need a 6mm Allen head socket and it's a good idea to break them loose before taking the calipers off the car, although after removing the brake line. Torque is between 60-70 ft/lbs for putting them back together.
