2012 Grand Cherokee Parking Brake Problem
I have a problem with my 2012 Jeep Grand Cherokee parking brake. A couple of months ago, I tried to apply the parking brake, and just as it tensioned as normal, there was a clunk type of sound and the pedal went to the floor with little tension. I didn't use the parking brake for a week, thinking I would take it for repair. One day, I tried it again, it worked normally for another week or so, then the same thing happened. I took it to the dealer the first time and they said the pedal and cable were fine and that they thought the problem was in one of the wheels. They didn't take the time to pull the rear brakes to really diagnose it because they ran out of time for the day, and I took my Jeep home. I have observed that when I push the pedal, I can see under the rear of the vehicle that the slack in the cable assembly is taken up, but the pedal still goes to the floor with only small amount of tension. I took my jeep back to the dealer this week to have them finish diagnosing and fix it. Now they say the cables are stretched and I need a new brake pedal/lever, yet they still never checked the brake assemblies in the wheels. Needless to say, when they told me they were going to replace all the cables and brake pedal, taking 5 hours and disassembling my car interior to do so, before checking the brake assemblies, I told them I was taking it home. When I got it home I noticed they sprayed WD-40 on all the cables where they go through guides (nice touch). I can disassemble and inspect the brake assemblies myself, but took it to the dealer since I have an extended warranty. The vehicle has 60,000 miles on it. What do you think the problem might be?
