| Check | ||
1 | Check if the notch of indicator disc (1) matches with the mark on camshaft (2) | ||
2 | Check the position of the camshaft on the indicator disc (1) | With the brake linings wear and the consequent brake shoe adjustment, the indicator disc (1) displaces in the rotation direction of the camshaft. | |
The camshaft reaches its maximum operating travel when the pointer of the indicator disc (4) touches/gets aligned with the reference on the adjuster housing (3) | |||
3 | If necessary, replace the brake linings | When the maximum work travel of the protruding shaft is reached, then this will be an indication that the lining thickness is approaching its wear-down limit, therefore requiring replacement even not yet having reached its minimum thickness. |
