Re: how to remove the rear brake drum on a 1999 chrysler...
The star wheel is accessible after removing the elongated rubber plug on the drum housing right next to the brake bleeder screw. Use a "brake drum spoon" to rotate the star wheel one click at a time. The proper direction of rotation is the direction the star wheel does not want to go since you are turning it against the hold of the ratcheting no-back. After rotating it several clicks, jiggle and pull on the brake drum and if it doesn't slide off with a normal amount of force, rotate the star wheel several more clicks. If I recall, the star wheel only has about 25 clicks of rotation or so before even brand-new, thick shoes are backed off away from the drum a significant amount to the point that the auto adjuster has a considerable amount of slack in it (no outward pressure).

does it have rear disc brakes or drum brakes, if disc brakes should be changed just like the front and you might have an emergency brake shoe inside the rotor that they call a halo shoe, if it is drum brakes take off the adjusting spring and the return spring remove the brake adjuster,the the brake bar then remove the brake shoe hold down spring by holding the pin from the back and pushing and turning the spring to remove from the pin, you might have to remove the the emergency brake bar from one shoe by removing the horseshoe clip from the pin on the shoe if you have problems putting it back together look at the other side that you have not torn down yet.
As you removed the brakes ,there is an adjuster on the bottom ,where the shoes go together .Is that adjusted down so to allow the drums to go on? If so some autos have a definate forward and rear shoe ,that may be looked at! Hope this helps!
