You should consider replacing the brake cable when you notice a decline in performance. The brake cables used on a bicycle consist of 2 parts the inner wire and housing. Over time the housing’s cable rusts, this causes the cable to catch on the housing causing things like the brakes not releasing properly.

Sometimes the inner cable is made up of twisted wires that become fray and break. If this happens on to you, then more than likely your brakes won’t work.

  • With the Allen keys, twist it to turn the pinch bolt in a counterclockwise direction to loosen the bolt. Then slide it out the brake cable.
  • On the handlebar, next to the brake lever there is a small barrel that secures the cable to the lever.
  • Slide the cable out from the brake lever.
  • Remove the outer cable housing from the bike and slide the inner cable out of the housing.
