The rear brake adjusters are mirror images of each other, including
threading direction. You need to turn BOTH sides UP to loosen! Looking
at it from the back side access hole that is.
As I have mentioned here before, it is very common for one or both sides
to be assembled wrong, preventing the self adjuster on one or both sides
from working. The 2 stiff return springs are not identical. If mixed up
the adjuster star wheel can be blocked from turning by the arm of the
spring hook. Both springs should be installed so the long arms are DOWN.
Carefully examine the springs to make sure no part touches the adjuster.
There is supposed to be one pair of mirror image springs on each side.
If someone mixed spring parts from both sides then it may be necessary
to sort them out

Prying with a screwdriver against the backing plate, you could see some slight movement around the lug bolts, but it felt like the shoes were holding the drum. E-brake cable was released..The drivers side brake shoes are tighter than the passenger side, significantly. I could just turn the drum by hand, after banging around on it some.Too tight, the way I've always adjusted drum brakes..
> So, from the archives, after perusing many posts, I found one saying you CAN 'fudge' the adjuster wheels for the brake shoes with a screwdriver..But for the life of me, I can't find one that works..Do I need to bend one up somehow in order to reach in there and turn the adjuster wheel? Also, the direction of rotation to move the shoes?.
> .From an archive post (Bently says nothing) I get that *to loosen the shoes you rotate the right wheel's adjuster upwards and the left one downwards*..So, taking the left side wheel: I bend up some implement that will reach into the little hole without hitting the other supporting structure. I try to locate the star wheel adjuster, probably by feel, since I can't seem to fit even a trouble light back there...and then using the edge of the access hole as s fulcrum, I lift my adjusting implement, causing the tip of said implement to rotate the adjuster downwards? And the opposite on the passenger side?
> I don't have the capability to loosen the axle nut..no impact wrench or large breaker bar...(broke all those trying to get off my Beetles axle nuts..After unsuccessfully bashing around (carefully) back there yesterday, I re-assembled and drove some. Got some 'squealing, squelching' noises from the rear driver side brakes when stopping..Also, after tapping back there, I found a pile of brake dust under the drum, indicating that indeed, I have a dragging brake there...
> So today, I want to try again..but before I spend all day doing it wrong, or devising a difficult way to accomplish a simple task, I thought I'd ask...Special tool to access the adjuster? and Which way does what with them?
