Still pitted

Postby noca » Fri Feb 11, 2011 1:14 am



I bought some piston from a guy really cheap for my 83 aspy. I should have taken a picture of them before I clean them up. They still pitted pretty badly at the top of them. can still use them. the had alot of surface rust and pitted everywhere. I you the use the method from the articles here to clean them. you can see some of the pitted. Not should if I can still you them. I guess the guy sold them cheat thinking I couldn't clean them up.

Yes yous can..first that part isn't going to be in contact with anything until the pads are really old..worn down.second the o ring in the caliper is wide so as long as the pits are smoothed out and won't catch the rubber they shouldn't leak even when/if the pits reach the o ring.

lastly you could try to fill them with JB weld and resand to smooth..if it worries you.

I think you mean the opposite, the pitted part is outside of the slave cylinder, so it will only come into contact with the seals when the pistons are completely recessed into the caliper, meaning new pads, not old pads!! Otherwise I agree 100% with all the above, you can use them as is or try any 2 part epoxy (like JB weld) to fill the pits and then sand to a smooth finish, I wouldn't bother filling the pits, but it is definately an option if you are concerned.

Man I had to read that first post three times before I understood it.
"It´s a friggen motorcycle, it´s not supposed to be comfortable, quiet or safe. The wind noise is supposed to hurt your ears, the seat should be hard and riding it should make you s**t your pants every now and then. "
