I have a 1997 jeep wrangler with aftermarket disc brakes on it. The guy that I bought it from seemed to have very limited knowledge about the jeep and I was hoping someone could point me in the right direction of what's is wrong and why the parking brake is not holding. I thought the cable attachment area seemed a little off with all the bolts but I understood where the guy was coming from because those bolts tend to slip after the first adjustment or two. The pads are in good condition and everything is in order for the regular brakes, why would the parking brake not be functioning?
