Brake Shoes and Parking Brake Adjustment

This is probably a simple question but I had trouble finding a definitive answer using the search function. If my brake shoes "need replacement" and emergency brake "needs adjustment" per my mechanic as quoted on an invoice while it was in for other work, what parts do I actually go pick up from NAPA or other auto parts store? I tried to reach him on the phone but he's too hard to catch in the office.

Based on what I could find here, I think what I'll need is replacement brake shoes and a hardware (springs and cables) replacement kit. Then just remove and replace. That should re-adjust the parking brake cable, while putting it all back together, right? What do you think? I haven't ever worked on drum brakes before, or any brakes for that matter, but the one drum brake r & r write-up I found seemed pretty straight forward.

Thanks for your time.

that's pretty much it. but i would get your drums turned, or if they are at their max then get new ones.

What does it mean to get them turned? How would I know they need to be turned? Sorry for the dumb questions. It's my dd, so I can't just hack in there and hope to figure it out.

As the brakes wear, they create annular grooves (like rings) on the inside of the brake drum. These grooves can affect the wear of the new brake shoes.

The solution is to have the brake drums "turned" so that the inside diameter surface of the drum is restored to a smooth cylindrical surface.

The tool that does this is a "brake drum lathe". Most bigger auto parts shops have one.

A bit of warning---there is a limit as to how much of the inside of the drum that can be cut away safely. It's marked on the drum somewhere. When the drum reaches this dimension, it must be replaced.

Before you install the adjusters, slide them apart, and coat them with permetex anti-sieze.

That is 1 of two places to adjust between the e-brake lever and the shoe/drum, the other is under the body of the Jeep where the cables meet the lever. It's a pain, since you have to vice grip the threaded rod while trying to loosen the nut. You should adjust inside the drum itself first, then re-set the cable where it works properly.

I appreciate everyone's feedback. I've been so busy lately that when Saturday morning came and I couldn't get past removing the drum, my better judgement stepped in and said to just take it to the local brake shop and get it over with before I got in over my head. Many mistakes under my belt, coupled with working two jobs and having a family I care about, have caused me to become much more careful with new projects.

I told them to replace the shoes and use a new hardware kit. I also had them replace both rear drums because they were out of tolerance. A few hours out of my morning and then spent the rest of the day off with my family. I consider that a success.
