Install a hose with an inner diameter of 5 mm  on the end of the friction spring (1). Open the friction spring so that the primary cable runs freely.

Use a pipe wrench to push back the primary cable mounting (2). Insert a 6.5 mm  locking pin into the hole in the pedal (3) (it must pass through the bracket, cable pulley, pedal and the other bracket).
