Listed among my many faults is the desire to take things apart that I shouldn't, like the above shift/brake levers. I got it back together but now the long lever doesn't spring back into position after shifting up into larger rear cogs. The long lever return spring is located under the grey plastic cover on the front of the lever. It fit in nicely when I reassembled it but it wasn't under any tension. My question is: Is this spring supposed to be wound up or under tension or does anyone have any other advice? The shimano pdf shows how to disassemble the rear (brake) part of the levers and says not to open the front part. (So why did they put a big screw there?) My LBM just laughs and makes cash register noises.

Here are two sites that may be helpful in solving your problem, otherwise I agree with your LBS, be
prepared to fork out some dough, cha-ching....Good Luck

Yes the spring should be woud up a little. About three quarter of a turn.put the spring in the
holes, one in the grey plastic cover and the one in the front of the lever. now turn the cover under
slight preasure, so the spring can't leave the holes until it''s in upright position and fit the
square iron bit.The hard part is. Find out how the spring should be. (two choises) finding out witch
holes to use (two choises) turnning the cover whitout teh spring leaving the holes turning the cover
in upright position with the cover hole slipping over the square iron bit before being upright

Good luck, It can be don, but not at ones, just keep trying (sorry for my poor english, i'm dutch.)

Good time to consider an Ergo conversion. Ergos & a rear Campagnolo changer can sum to less than DA
STi levers. And Ergo are _easily_ rebuilt.

hats off to Mr Cotton but really. . .
