Brake return is slow

On Super Wheels by Carter model 2575, band brake, what makes the brake pedal return? What else should I look for? The rod runs by the frame in a couple places but seems to be bent correctly.

Sometimes the springiness of the band brake is enough to return it.

Manco karts have a torsion spring added to the pedal or an extension spring added to the brake rod.

Also, make sure there's no binding in the linkage. Everything should be nice and loose, especially at the front end/at the pedal. Don't forget to lubricate everything with a decent lube.

I use 30W motor oil in one of those old fashioned oil cans. Puts a precise drop or two right where I want it.
