Front, passenger side piston sticks when cold and when going slow, locks up upon braking.
I think it's just a piston problem. Can I lubricate it somehow?? Brake cleaner?? WD 40??
Don't want to replace it!!

If it's original equipment, you may not have a choice.  Over time and with a little moisture in the system, the caliper bores can start to pit and give the piston a surface to hang up on.  You should be able to get the calipers rebuilt relatively cheap though.

yea it sounds like the piston is hanging up internally, youll need to rebuild, replace, or learn to live with it I guess.
