[QUOTE="Nigel Spaxman, post: 110613, member: 2907"] Gary, the first part is wrong. When you apply the brake there will be tension in the cable 10 lbs if you have very weak hands. That tension pulls up on the left hand brake lever, but it can only do that by pulling down on the balance beam (which then pulls up equally on the other side). If the force in the cable is 10 lbs at the handle bar then the force is going to be 10 lbs on both cables. You are not building a perpetual motion machine because the travel is halved. The reason I had to modify my lever is instead of using the original type that has the 7/8 pivot distance. That is the type the Speet brakes are designed to use as well. I used a Dourhety lever because I like those. They have the 1 1/8 pivot distance. [/QUOTE]
