Removing the 4 13 mm bolts on the rear brake drums

Hi Rich. Removing nuts and bolts associated with brake systems can be a real pain.

I use one of two methods to loosen frozen bolts, depending on the situation and how much of a hurry I'm in.

• The first method is to spray a penetrating oil such as PBlaster (available at any auto parts store, or maybe even big boxes like Wal-Mart). Liberally spray around the head of the bolt so the lubricant can seep down into the threads. This can take quite some time, and involves the process of: 1) spray, 2) wait, 3) try to remove, 4) repeat. Depending on the amount of rust involved, this process can take hours. OR, it can work in a matter of minutes. It just depends.
• The other option is to alternate between heating with a propane torch and hitting it with with a hammer. The material expansion associated with the vibrations from the hammer impacts can break the rust bond. This is something of a brute-force approach, and can yield mixed results if you're not careful.

Once you get the drums off, hopefully you have a good pair of vice-grips to get the broken bolt out. I've been where you are. You have my sympathy! Good luck and let us know how it goes.
