Looking for a little guidance here: ‘97 Wrangler and the parking brake won’t hold the vehicle on the slightest incline. I took the Jeep to Les Schwab, they said the rotors are good, the pads are good with 5 mil, and they also adjusted the brakes. The brake handle was adjusted and feels completely normal when pulled. Underneath the Jeep the cable from the handle is loose when the brake is released and taut when it is pulled. Both cables to each rear tire are loose when released and taut when pulled. Everything looks completely normal and functional, it’s just that the brake won’t hold the Jeep in position. Has anyone had a similar problem and what are my options going forward here? Thanks in advance!
