I can swing the large lever to the left but encounter no resistance, unlike when I swing the smaller lever I will get a small click.
Any suggestions? Thanks!
As a bike shop owner for 12 years, I can tell you that coagulated/hardened grease in Shimano shifters is a common problem. It may not be necessary to replace it. Try this: Have paper towels handy; this is a messy job. Unflip the small lever on the brake caliper or detension the brake wire. Strap the brake lever so it is engaged. Pour 2" of oil in a shortened 2 1/2" tall paper cup. Motor oil is ok. Take the front wheel off and lean the bike on the fork. Submerge the portion of the shifter with the ratchet mechanism for a minute or so. Wipe the shifter and see if the levers work. You may have to shift through the gear range several times. Good luck.
