Change the rear brake disc. (

p. 126)
Danger of accidents
Incorrectly tensioned spokes impair the handling characteristic and result in
secondary damage.
The spokes break due to being overloaded if they are too tightly tensioned. If the tension in the spokes
is too low, then lateral and radial run-out will form in the wheel. Other spokes will become looser as a
result.
-
Check spoke tension regularly, and in particular on a new vehicle.
-
Strike each spoke briefly using a screwdriver blade.
Info
The frequency of the sound depends on the spoke
length and spoke diameter.
...
If you hear different tone frequencies from different
spokes of equal length and diameter, this is an indica
tion of different spoke tensions.
I
You should hear a high note.
If the spoke tension differs:
-
Correct the spoke tension.
-
Check the spoke torque.
