I have seen others convert rear coaster hubs to drum brakes for their front wheels, but I dont have an extra coaster hub or access to welding equipment to do the necessary midifications. I have also heard of what some call "suicide brakes," where instead of a sprocket, there is a rod and cable attached to the brake lever, and the lever is clamped to the front fork the same way it would clamp to the rear chainstay. but I can find detailed enough instructions to make this modification. I know that I can remove some of the coaster brake components from the rear hub and basically convert it to freewhheel. my plan is to use the coaster brake arm to adapt some sort of drum type brake to the front wheel, and i was thinking of attaching a return spring and a cable, so that when you pull on the handlebar lever, it pulls the brake arm up, and when you release the handlebar lever, the return spring pulls it back down. I was thinking I could take the cone that the brake arm bolts to and replace it with a cone from a parts mountain bike I have in my basement. the idea is that the brake lever when pulled would push the cone against the bearings, stopping the wheel. when released, the arm would back away from the bearings, releasing the hub to move again. a possible drawback to this would be wearing down the bearings faster, or ruining them completely. any thoughts on this?
