If you go to www.partsfish.com or www.bikebandit.com and look at the HANDLE
SWITCH LEVER parts diagram, you will see that item #4 is the STOP SWITCH
ASSEMBLY.

There is no external spring directly associated with the switch, but there is
probably a spring inside it.

Also, if you look at the FRONT MASTER CYLINDER 2 diagram, you will see that
there are springs inside the master cylinder which push the brake piston
pusher back to the normal position when you release the brake lever.

If you are having problems with the brake lever feeling very hard and
applying the brakes immediately with the slightest pressure, change out the
brake fluid and make sure you clean out the tiny air bleed hole in the bottom
of the brake fluid reservoir.

Excess air pressure builds up when the brake fluid gets old an blocks the
bleed hole.
