5) Using a spring scale, measure the rotary sliding resistance of the hub in the forward direction.
6) Obtain the drag force of the disc brake (the difference between the values measured in 5 and 1).
Standard value: 70 N (15.4 lbs.) or less
7) If the drag force of the brake exceeds the standard value, disassemble the piston and check for dirty or corroded piston sliding surface and deteriorated piston seal.
