I bought a Caldwell that came with CSP disc brake conversion, I'm returning it back to drums for vintage. I'm having a lot of trouble getting the grease caps off the front brakes. The rotor hat is aluminum and I don't want to get too rough and score the crap out of the nice machining. There's two notches in the hat but that sucker is in there tight. I'm pretty sure it's not a screw-in, I don't have the tool for it in the parts. The caps themselves are stainless steel.
Any tricks for getting stuck grease caps off without ruining the rotor hat? Hopefully heat isn't involved, I don't know if PB Blaster would help or not. Never had a problem like this on my Chevy!
Thanks!
