I posted a few days ago about a Schwinn Le Tour bike I found. I did a little cleaning on it and thought it was looking good.It has Shimano RSX shifters/brake levers on it , which I have not seen before. The brake lever pivots to the side to downshift and a smaller lever that is attached to the brake levers upshifts. Neither one worked so I decided to try to clean them with some carb cleaner and compressed air. I removed a screw from the left/front one. A spring "unwound" inside and I can see no way to reassemble the thing. I was looking forward to riding the bike.
