How do you remove the rear brake drum from a Mazda B2200?

First you need to have the rear axle jacked up on a stand or jack.Dissengage the parking brake have the truck in park or in gear if manual.Use a brick or wheel block to keep the vehicle secure.To remove the rear drums it has 2 set screws that typically are Phillips head (use some liquid wrench or any penatrating fluid if they are rusted or not removed over a long time).You remove them and will reinsert them into the 2 holes 180 degrees opposite of the location they came out.Simply use a screw driver and run them in equally this will push the drum off the shoes.Sometimes the drum will stick and u can use a large pry bar or flat head screwdriver to evenly pry the drum away from the backing plate.You may also may have to tap the drum with a hammer to loosen this as well.I would spray the penatrating fluid around the studs and hub(on the front side)so it will slide off easier.And if the set screws are really tight place a set of channel locks onto the Phillips head handle to give you leverage to break loose the screws if they do not come free u can grab the channel lock while holding the screw drvr in place.Always if u plan on replacing the rear brakes do 1 side at a time so you do not place the springs,and push rods incorrectly.Hope this answers any ?s you may have and if the set screw head gets stripped out,simply drill out the head and buy new screws like at lowes (I have had this happen use a smaller drill bit so not to damage the hole).I recommend using antiseize on these two screws when u reinstall them in there original location.They hold the drum tight to the hub.OK
