so I searched & searched and I haven't had the opportunity to pick up a service manual yet but looking for info on rebuilding front brake calipers. I think I have one hanging up. I have to say that self help section is FANTASTIC! Can someone please point me to the information that I am sure is here I just can not find? Thanks again for the help. This is why I am thinking they need rebuilt - I was riding home Sunday and it sounds like the brake squealers on the car brakes are coming from my front wheel. As soon as I apply any front brake pressure it goes away, and to my knowledge there are no squealers on the bike brakes correct? So I put the front end up a little yesterday and there does seem to be some drag on it, I can't get a full revolution of the tire when I spin it without continuously pushing on it. Also it appears that the outer top piston is out further than the other one, but I didn't have much time to play with it. Any advice would be greatly appreciated! Thanks for the help!!!!
