I just had my 02 burb 1500 in the shop for 30k and 36k service, $700 later, I'm out the door. My driveway is at a 10-15 degree or so incline, where it is normally parked. The e-brake goes to the floor (no ratcheting and smooth like usual), but when I go to move the car, I take the e-brake off and switch out of Park, I get a "kaching", like the tranny is the only thing holding it in place. I test it and it is the only thing holding the car in place. WTF? I call the dealership, figuring I'd get a line of crap. I'm told that GM changed their e-brake set-up with 2000& up trucks and use a smaller drum system outside the rear discs in conjunction with the tranny to hold the vehicle in place. He said that it barely holds the car in place on level ground. What kind of BS is this? He also said it takes only a block or two to smoke the "drum" brake if left on (there are enough lights and alarms that only an idiot would leave one on). What's the story?
