I too have rebuilt Autozone calipers on my truck. I got them around six years ago for a "great price" of $40 each. Well, each time, they work fine for about 18 months and then a piston sticks and they eat the pads like crazy, create tons of brake dust and make bad graunchy noises at the end of low speed stops. Every time this happens, I trudge down to the store and get two freshly rebuilt calipers and pads. Even though they are free, I still have to get all dirty, waste several hours of a Saturday, buy a bottle of brake fluid, and beg the wife to pump the pedal while I bleed them. What a pain! The last time I replaced them, I took my old ones in, got home with the new parts and while I was installing them, something didn't feel right. The brake line fitting on one caliper screwed in deeper than usual. It tightened down fine, so I filled and bled the system. The next morning, I went to drive my truck and the pedal was soft. I backed it up a few feet and saw a puddle <img src="/forums/images/graemlins/angry.gif" alt="" />. I pulled the caliper only to find that it was missing the steel insert. I'm not sure how they missed that when rebuilding it. The fitting simply bottomed out on the casting rather than forcing the flare onto the steel cone seat. Luckily, Autozone had another caliper and I was able to get it back together, but I had to make another trip across town and bleed the system again. Of course I needed to buy more fluid too. The parts guy at Autozone had no idea what I was talking about and couldn't even tell the difference when I showed him the defective caliper next to the one he pulled off the shelf. He shrugged and handed me the box. At this point, I don't know if I should keep replacing them or use them as cores at a real auto parts store. The LH caliper is hanging up again, so I will have to do something in the next month or so. The truck is getting rather rusty and it has 255,000 miles on the original 3VZE, so I hate to waste the money, but I'm tired of replacing the calipers all the time.

I will never buy anything like this again at Autozone.
