Note

When installing the brake disc, make sure that there is no dirt or residues of thread-locking compound between the wheel and the brake disc. The mating faces must be smooth and clean.

(-) Measuring brake-disc runout

Install dial gauge (No. 00 2 510) in dial-gauge holder (No. 34 2 524) and install measuring adapter (No. 34 2 510).

$D:\BMW\RepROM_K2x_GS\Datas\RepRom\BMW-Motorrad/imgs/icon/bullet.gif$

Mount dial gauge holder on the brake caliper mount.

$D:\BMW\RepROM_K2x_GS\Datas\RepRom\BMW-Motorrad/imgs/icon/bullet.gif$

Align dial gauge in such a way that the measuring adapter is in contact with the brake disc close to the outer circumference and the dial gauge is slightly preloaded.

$D:\BMW\RepROM_K2x_GS\Datas\RepRom\BMW-Motorrad/imgs/icon/bullet.gif$

Set the dial gauge to "0".

$D:\BMW\RepROM_K2x_GS\Datas\RepRom\BMW-Motorrad/imgs/icon/bullet.gif$

Slowly turn the wheel through at least one complete revolution and observe the dial gauge reading.

$D:\BMW\RepROM_K2x_GS\Datas\RepRom\BMW-Motorrad/imgs/icon/angle.gif$

The sum of the positive and negative dial-gauge readings is the total runout.

Check positioning of the brake disc/wheel rim.

$D:\BMW\RepROM_K2x_GS\Datas\RepRom\BMW-Motorrad/imgs/icon/bullet.gif$

Check the wheel rim for damage.
