For some reason my e-brake never has been right. I have always adjusted it during oil changes ETC. and it sort of worked OK. Recently it just doesn't hold. I have the rear shoes up as tight as I dare, but that doesn't help. I push on the e-brake pedal and it will go down and I feel a small amount of resisitance, but when I take my foot off the pedal it either engages or doesn't. Usually doesn't. I believe there is another way to adjust this but I'm reluctant to start messing with the cables without some sort of assurance it is the right thing to do.
