• Normal forces.
  • Effective radius of the brake pads.
  • Material suitability testing.
  • Co-efficient of Friction.
  • Braking torque.
  • Sliding forces.


  • 3 different positions for brake pad sets, 20mm intervals
  • Brake pads in steel brass, nylon, brake material (one each)
  • 2 hangers of 0.5N each
  • Set of slotted weights

Brake discs are mounted into a sturdy frame which needs to be mounted vertically either on wall or on stand. A single shaft runs through the brake disc and the wall bracket supports. A cord pulley mounts to the shaft onto which is mounted a cord terminating in a load hanger. A lever is mounted on upper side of brake disc which is moveable on the length of shaft and contains brake pads. The brake pads are made of differents friction material. Through the load hanger and calibrated weights the leverage load is applied to the brake disc and the parameters of braking force, braking torque, normal force can be assessed. All load hangers, and calibrated weights are supplied with the apparatus. Different brake pad materials can be tested as well as their radial position on the brake disc. A comprehensive instruction manual giving full details on apparatus assembly and operation as well as example results. All necessary assembly and operational tools are provided.
