Adjusting
If the brake disks are getting thin, it will be difficult to get the hand brakes tight enough.
If so, replace the brake disks. (The brake disks shall be minimum 18 mm thick.)
NB! If the two bolts that hold the brake disk in place are gone (broken),
the brake disk must be immobilized with the wheel bolts (not the bolts to the aluminum wheels; they are too long).
To adjust 4x 11 you can use a large flat screwdriver or
a square awl where the outer tip is removed. Or make yourself a special tool of 4.5 mm thick metal:

- Jack up the front of the car, put it on stands, take off the road wheels and put the gear stick in neutral.
- The hand brakes must be disengaged.
- Unscrew the lock nut and the adjustment nut on the wire both sides (2 11mm wrenches + small
spanner
to hold the end of the wire).
- Loosen 4x17 (17mm).
- Adjust 4x11 (clockwise seen from behind), first at the outside, then on the inside and
tighten 4x 17. (4x 11 must be tightened/turned just so much that you can easily rotate
the brake disc with your hands with a little resistance. Be sure not to touch the brake disc, hold onto the edge.)
- Pull out the wire first on one side, and then on the other side. Measure the difference and screw
back on the adjustment nut and lock nut on both sides. (If the end sticking out on the left
side was 5 mm longer than the one on the right, it shall still be sticking out 5 mm more wire on the left side.)
- Test that you can turn the brake disks around with your hands, and that they (the brake disks;) are completely clean.
On alloy wheels the end of the wire might hit the rim. If so you can
try to shorten the small set screw
slightly (2 8mm wrenches) and realign. If that does not work either, you can pull out the wire
and put on a few washers or a nut or similar.

If you cannot get of the lock nut and adjusting nut, you must replace the cables.
Tighten 4x17 7.5 mdaN (75 Nm).
Tighten the lock nut 1.5 mdaN (15 Nm).
Put grease on the wire and pull a plastic hose onto it so that the hose will remain under the trigger guard.
