OK, well I will give the pistons a good cleaning tonight and see if that helps. I was at Meijer(walmart like) but they did not have any good sand paper to clean the pistons. All they had was 220grit and I really think micr cloth or plumper cloth would be better yeah? What should I use the clean the pistons?

 

Be veeeery careful with sandpaper, the red scotchbrite pad would probly be best but you can probly do it by nicking one of these from the cleaning closet:



Specially if you soak the pistons in gas, diesel or brake cleaner before (any of those will swell and destroy the yellow part so chuck the pad when you`re done)

The more you have to put elbow grease on it the less danger the pistons are in

 

I would not use sand paper. Some pistons have a coating. You don't want to remove that. You're just trying to remove grime and brake pad residue. If you pistons are to the point you need to use sand paper, then you probably need new pistons.

I usually just spray them with brake cleaner and let it soak for a minute or 2. Then clean them with paper towel and some elbow grease. Repeat if necessary. On really tough spots I'll use a scotch brite pad (white) or a toothbrush and a very light scrub. They should clean up nice this way without resorting to sand paper.

 

ok. thx for all the feed back I will post up if this fixes the problem or not.

 

Well I got the pistons out using a compressor and it seems my pistons are pitted a little and there are lite spots around it where the finish is coming off. I guess I will have to replace the pistons... fun. My bikes new name is Hostage, shes a fighter.
