e brake question

Hey guys, this may sound stupid but a first for me ,i just changed the shoes on my 07 tacoma sr5 prerunner 4x2 and i adjusted the brakes and they felt hard to my wife when the truck was off and when i went to make them self adjust in reverse the pedal dropped to normal height,but then when i went to apply the e-brake in my driveway with i a slight slope my truck just rolled forward,the truck stops fine but the e brake doesn't do to good on even a slight slope any suggestions on how to correct this little problem?? any tips would help greatly and very much appreciated since paying a dealer do fix or repair my truck is insane if i can do it myself....GOD BLESS

 

Readjust shoes, put drum on pump brakes, pull ebrake, repeat until you can only move it 3 or 4 clicks with moderate pressure
