so a few years ago I had a parking brake issue and the drum assembly fell apart inside of my rear rotors. Lucky this happened as I was backing out of my driveway and I parked the truck and removed the rear wheels to find the issue before I caused major problems. so I replaced both assemblies for the parking brake but I never got it quite tight enough to be effective. No when I push on my parking brake pedal to engage the break I got a sort of spring pop noise. Its as if a spring is under tension and then breaks loose. What is the issue with my parking brake?? Any help would be greatly appreciated. 2010 Nissan Titan SE Crew Cab 4x4
