brake help...

[koukis4teen]

I'm not sure if this is the correct section but i need some help.. I got some z32 brakes for my car. I took them off a 300zx w/ 160xxx miles. so i took out the hardware and was going to rebuild them before installing them on my car cuz a brake up grade isn't really a upgrade if it is not done right. A boot or two is torn but nothing looks majorly messed up. My question is about the pistons.. they all have quite a bit of rust on them.. when i removed the pad a substancial amount of rusted metal flakes fell out. they seem to be pitted. I don't know if this is typical for brakes this old. All the rebuild kits i see are just seals and clips and you reuse the pistons. i feel like my pistons should be replaced but dont see a kit including them or a place to just buy the pistons. if anyone has advice on what i should do thatd be great, maybe i am making something out of nothing with this rust but i felt like a piston should have a clean machined look.

Pics would help.

If its light surface rust, you may be able to sand it off.

Anything more and you'll probably need to either buy new pistons or get them machined.

ill try and get pictures up tom... the rust i speak of is like inside the recessed part of the piston so maybe only thing that matters is the condition of the sides. i know its dumb not to have them but i was hopin maybe someone would know where i can get pistons or about how much they cost im thinkin oem from nissan is the only way... i didnt take the pistons out yet. mostly cuz if i can't find new ones it wouldnt be much point so i jes kinda been holdin off. thanks for posting man.
