   Squeezing the brake lever tightens the cable against the channel to produce braking friction. [49] A return spring slackens the cable when the brake lever is released, no adjustment is required, and the brake becomes more forceful when wet. Husted said his inspiration was the band brake used on industrial machinery. [50]
