hey i acquired a cheap coaster bike frame... turns out its really cheap i finally got tires and tubes on the wheels... only to find the brakes didnt work hardly at all... well i took it all apart hoping to be able to repair it but i dont think i can... it only had one brake pad, the clutch ass. inside washer is curled up on itself(is it supposed to be?)... im stuck im really new to all this. can i buy single brake pads from somewhere??? i checked ebay to no prevail... im thinking about just scrapping the whole wheel... any advice???
