In a 2001 chevy tahoe, if there is no tension when the parking brake is engaged, and I have to physically pull the brake back up with my hand(it does not spring back when disengaged). Which brake cable would most likely need be replaced
There's at least four. You're going to have to check them. We can't tell over a computer. Probably the most likely one would be the intermediate cable which just connects on each end to the two rear cables, and the front cable pulls on the middle of it.
