yeah at full lock my ebrake is hardly noticeable, i can drive away haha.. may be a good idea.!
Actually that has nothing to do with it, lol. It just that with most drum/e-brake systems, the ebrake forces the shoe out and puts the "shoe return spring" under tension.
Over time they are gonna get weaker.
As for your e-brake either the cable is stretched (very common is 72-93 Dodge trucks) or you need to make adjustments at the brakes.
