says it all.. (3 page tiff, view with something like irfanview)
Somehow I cannot find this page on the
web version of TIS. This is an export I made from the DVD version
This is the auto adjuster that you need to push back in that little retaining clip:
I used here a tyre iron, but a really long screwdriver is even easier (perhaps you need both).
At the tip you can see the retaining clip, which sometimes has to be pushed to the side to grip.
If not clear: here is the auto adjuster situated:
(at the base of the brake lever)
This is the little wheel adjuster (inside the drum/disk) that you have to turn with the disc mounted (with a screwdriver through the hole of a wheel bolt):
In short:
1.push back the auto adjuster in the retaining clip
2. turn the expander wheel in the drum brake until you cannot move the wheel.
3. turn back the expander wheel 9 notches.
4. Release the auto adjuster from the retaining clip.
Sometimes I turn it back less than 9 notches, but the wheel definately shouldn't drag on the pads.
