Brake Lever Travel
Squeeze the brake lever. It should move no closer to the handgrip than 1/2 in (1.3 cm) 1 after max lever adjustment. A smaller distance indicates low brake fluid level or air in the hydraulic system. Your dealer can assist.

Make sure the brake lever is clear of any obstructions, including items that are mounted to the handle bars, such as the throttle block, kill switch, handguard or gauntlets.
