2004 liberty

[ve77er]

I just did a complete brake job (pads and rotors fornt and rear) on my neighbor's 2004 Jeep Liberty, when I removed the rear rotors, the right parking brake shoes fell out and the left side were non-existent, I am wondering if some of our fine moderators here have ever experienced a similar situation, the neighbor, was quoted almost 800.00 for the brake job at a local shop, I was able to buy all the parts for less than 200.00 and about 4 hours all told for labor in my driveway. she was thrilled but I am really wondering about those parking brake shoes???
