Checking the brake
Remove fan cover (2)
Remove stopping plug (3)
Measure the air gap (S) with a feeler gauge (b).
NOTICE
When measuring, ensure that the feeler gauge (b) is slid up to insertion
depth “a” as a minimum and does
not become caught on the ledge (!). Refer to the
table for the maximum permissible air gap (S). The brake is not readjustable. Once
the max. permissible air gap (S) has been reached, the brake rotor must be replaced.
