Sounds like you have air in the system, youll need to bleed them, if that is the case. You should first pull the drums and inspect the shoes. I replace them when the linings are worn to 1/32" or less. I use a cheap plastic vernier caliper to measure linings, but a tape will work. If the shoes are shot, go ahead and take the drums to a good shop to see if they need to be turned, I had two drums turned at a local parts store for $15, cheap insurance. When thats all squared away, install em, adjust em, and bleed the system. Trust me on this, you want your brakes to work, you never know what may happen!! tips on bleeding brakes.
