Question about Shimano Cycling
You can squirt them with a spray lubricant (bicycle lubricant) to free them up if it is just a dirt issue, you need to pull the brake lever to expose the internal gearing mechanism, don't take anything apart.
If your shifter part is sticky, this usually clears things up. If it does not make trace through the derailleur cable and make sure it's not the cable hanging up instead of your shifter. Replace the cable and housing as necessary.
If its the brake lever, smae check of the cable system but also check the brake itself. The lever will feel sticky when there is a snag in the cable or if the brake is no longer returning with the same spring tension.
After that you can have them rebuilt or replaced. Depends on which model you have 8, 9, 10 (7800, 7900) as too the exact recommendation.
