This happened to me on both brake pedals, nothing happened when I tried.to put them on, the pedals just did not move at all. I tried adjusting the brakes as per the dorel video on you tube, but still nothing. My husband found the solution though. He worked some oil into both pedal mechanisms and worked it through until both pedals moved again, once he had plied through a couple of times, both pedals and the brake now work fine, just turned out the pedals has seized over the years and just needed a good oiling. Worth giving this a try.

Can u email close up of brake handle n wheel from inside where brake is n ill tell u how to fix
