yesterday i let my friend ride my motobecane. when he came back, the front brake was not working. at first when i pulled the lever it would stick and the actual brake mechanism and lever wouldnt spring back. i bent the drum (i think it was the drum) and now the brake itself springs back but the lever doesnt. also, the brake isnt as effective as it was.
at this point, would the brake problem be cable tension related? or is the root of this evil in the drum?
also, my rear brake has never really worked well. the cable and lever are fine but the brake doesnt really bring me to a stop. is there any way to adjust this or is it time for a new brake?
