Brembo B2B Lever The primary advantage of this lever is a 50% reduction in actuation force. This means less fatigue, less arm pump and more endurance especially during high intensity race conditions. Our innovative brake levers are engineered to reduce both finger fatigue and arm pump thus increasing endurance during high intensity conditions A "shorty" lever length allows a one or two finger operation enabling you to squeeze the lever to the bar without releasing your grip with the rest of your fingers. Depending on the mounting position you employ, you can even go for a three finger grab when necessary. Installation instructions 1 . Remove old lever. 2 . Install new lever. 3 . Make sure piston rod is seated in the small recess. 4 . Use some lube on the pivot if you want to, it helps. 5 . Reapply Loctite on the lever adjustment set screw as necessary. 6 .
