Loosen the brake line at the wheel cylinder. Make sure you have something to catch the expelled fluid. Tighten the line after you push the shoess together. Goodluck
you may have to repl wheel cyl, then tend to leak after this happens
Also check the parking brake adjustment . If it's a self-adjusting parking brake you will need to find out the method to reset it or it will still be difficult to install drums
