Steve, Mike (Spicer) is correct. All the levers on the left side pivot on the same shaft. Looking at the illustration below, that pivot shaft is item #14. When I took mine apart, the shaft was corroded. Cleaning that up and adding a little lube should take care of your problem. To get at the shaft, you'll need to remove the left side plastic console. It's bolted on from underneath the fender and you can even get to the bolts without removing the wheel. With the console off you can unbolt one bolt on each end of the shaft and slide it out so it can be cleaned. That's what I'd suggest as a first step and probably will be all you need.
