Hi, just new here.. I want to find out about the brakes on a Colt Major failing to hold on a hill.. I've had the brake pad repaired on mine and it still don't stop straight away when taking my foot off the pedal neither does it hold on a hill. I have tried adjusting the bolt that holds the belt pulley tensioner forwards and backwards on the floor next to where the throttle is situated but it doesn't seem to help. Does someone have any idea what is causing this problem?
