I installed a double brake lever on my 2 stroke bike so that there'd be only two levers on the handlebars. The first problem was the C type sidepulls required a LOT of grip pressure to stop the bike quickly. After hearing about the combination throttle, kill switch and dual brake lever in another thread on this forum I ordered one. It has the advantage of a longer lever which yields more leverage and faster stopping. I got it yesterday and decided not to use it. The cables are attached to the lever in a way that doesn't allow them to pivot on their round barrel shaped ends. Instead the cable will be bent at the hole where it exits the lever each time the brakes are applied. This continual flexing of the cables where they emerge from the lever will cause accelerated fatigue and failure of the cables. I decided to use the original double cable lever lengthened the brake lever by epoxying on a piece of steel tube that just slipped over the brake lever after cutting off the turned up end. The new lever is about 6" long measured from the pivot bolt. It greatly reduced the grip effort needed to stop the bike. This lever system has the cables connected like most normal brake levers which don't bend the cable so the brake cable life should be a lot longer. I adjusted the brakes close to the rim so now if one cable breaks the lever will still operate the remaining brake so there's very little chance of losing both brakes at the same time. If anyone has one of these type combination brake and throttle units it would pay to take a careful look at the way they work.
