2005 Escape front wheel drive, rear drum brakes. 84,000 miles. I am trying to remove the rear drums from my Escape. First I wire brushed all the rust away from the center hub. Then I used the tap between the studs method. Then PB Blaster and the same tap method, then heat from a propane torch and the same tap method. Then my taps became more aggresive. My Ford workshop manual says if the drums do not come off easily to tap between the studs. It states not to use heat or a puller to prevent distortion. I did use my propane torch wich is not a lot of heat in my book. I have been tapping for over an hour. I should mention when I replaced the front disk and pads a few months ago I had to use a puller along with tapping to get the disk off. It appears on the front disk and rear drums it is the area under the disk/drum that is rusting and causing the problem. Any ideas? My next move is to use a puller, but I do not have much room behind the drum and backing plate.
