How to Install an Arai Tandem Brake

Arai tandem brakes work best when used to control braking rather than stopping. It requires more cable than normal braking systems and needs its own handle. This gives the rider more control when braking is necessary. Because they don't work against the rims of the wheel, they help even more by keeping the temperature on the rim created by braking to a minimum. The one thing that you shouldn't overlook while installing the Arai tandem brake is to assemble it with clean hands; oil or grease will cause the tandem brake to fail.

Instructions

    • 1

      Grease the threads on the hub. Screw on the larger of the two drum parts on the left side of the hub.

    • 2

      Secure the smaller of the two drum parts, known as the brake plate, to the axle. For a Hadley hub, remove the left axle cap followed by the washer. Install the brake plate and then re-install the axle cap. For Shimano hubs, remove the outer lock nut and the washers. Install the brake plate and then re-install the hub.

      Insert the hook bolt through the chrome-plated brake arm and secure it with the lock nut. Tighten the nut until it is snug but can be spun.

    • 4

      Place the anchor assembly on the end of the cable into the concave on the hook bolt. Be certain that the end of the cable sticks through the slot. To remove the cable from the brake, pull the end of the cable away from the wheel. This frees the cable from the hook bolt.

      Install the long Allen bolt through the anchor arm of the brake plate. Slip the lock nut on the end of it and tighten it down.
