I have done many different brake jobs on the various cars and trucks that I have owned over the last 30 yrs. I have a 95 Buick Century that I am trying to do a rear brake job on and am totally stumped. I cannot find a schematic or exploded view of the rear drum brake system. Chiltons takes my money and then their books show nothing. I have one side apart and can not figure out how to get the large U shaped spring, that holds the entire assembly together and against the baking plate, back on! Any suggestions or special tools necessary... Help!
