How to Tune Avid Juicy Disc Brakes

Avid Juicy disc brakes use hydraulic fluid to give the needed braking power on the mountain bike. The brakes also use a barrel adjuster off the shifter and brake lever; this design gives the rider the ability to adjust the brakes on the fly. Brake adjustments are also done on the drum with an Allen key. These disc brakes are made by Sram, a mountain bike component producer.

  1. 1

    Set the bike so it is standing upright. Look at the front wheel and the disc brake drum --- the metal cylinder where the caliper clamps down. Look to see how much distance is between the drum and the caliper, the C-clamp that grabs the drum to stop the bike.

  2. 2

    Put the Allen key into the allen screw on the caliper and turn to the left to decrease the distance between caliper and drum. Turn to the right to increase the distance. Keep 1 to 2mm of distance between the drum and caliper.

  3. 3

    Hop on the bike and begin riding. Test the brakes by pulling the brake levers in toward the bike. If there is too much slack on the levers, turn the barrel adjustment on the outer edge of the brake lever one-quarter turn to the right. Turn the adjuster one-quarter turn to the left to loosen and increase the slack if needed.

  4. 4

    Make one-quarter turn increments until you achieve the desired brake setting.
