05 Liberty parking brake
I'm having an issue with my parking brake where it doesn't work. A little history:
I bought the Jeep used about a year ago, and noticed, within days that the parking brake didn't work well. I took it back to the dealership, and they said the brake lever was broken, ordered a new one, replaced it, and the parking brake was tight, and held the Jeep, even on an incline. Then a few days later, I heard a something snap when driving down the road, pulled into a parking lot, and knew what happened when I tried to set the parking brake, since it was quite loose, and pulled up all the way.
I took it back to the dealership, they said the part must have been bad, ordered a new one, replaced it, and again, it was tight and held the Jeep. Again, a few weeks later I heard a loud snap, while driving, and the parking brake was loose, came up all the way, and didn't hold it well.
A few weeks later I had it at a different dealership for some warranty work. I mentioned the issue. Their mechanic said he tightened the drums, and that seemed to do the trick. Then, within a few weeks, the lever was loose, and didn't hold the Jeep.
A few weeks ago, I pulled up the center counsel to look at the brake lever. I noticed that there was a piece that could be moved by the lever, and it would tighten it up, or loosen it. The first and second image show when the lever is tight, and the third and fourth when it is loose. I tried leaving it tight, but then noticed the first time I used the parking brake, the brakes were sticking, and even after loosening this piece, they were still sticking. I removed the rear tires, and the regular disk brakes looked great, but I had to loosen up the parking brake star adjuster to remove the rotors to inspect the parking brake shoes. One of the shoes had broken off of the backing plate. I just loosened the both up big time, and I will replace them.
Sorry, I know that was long winded. Do you think that just replacing the parking brake shoes/springs/turning the rotors, along with tightening up the mechanism on the parking brake lever will be good enough, or might the new shoes start sticking again? Might I need to replace the parking brake lever again? What would have caused whatever it is to snap soon after installation on two separate occasions?
Thanks in advance, and sorry again about being long winded
