Brake pad wear indicators
1 - overlay;
2 - wear indicator;
3 - brake disc;
A - a new overlay;
B - worn lining.
Despite the possibility of monitoring the thickness of the brake linings by means of a wear indicator (some models), we should not forget about additional visual control, which should be carried out more or less regularly and not only before a long trip.
The minimum thickness of the working layer of the pad is 2.0 mm.
For a quick check with the wheel cover removed, shine a lamp and evaluate the thickness of the lining. More accurate is the control with the wheels removed.
Check pad wear with a ruler.
