Steps

1. To check the wear of the brake pads, you must therefore check their thickness
2. The minimum thickness of brake pads should be 3mm
3. In general, the thickness of new brake pads is approximately 15 mm
4. /!\ Some garages have a special visit for this check, otherwise it will be done during the overhaul and technical check
5. > Brake pad wear also results in different symptoms:
6. A loss of braking efficiency, which corresponds in particular to an extension of braking distances
7. Noise when braking
8. Vibrations when braking, mainly in the brake pedal
9. A soft brake pedal
10. Overconsumption of brake fluid

Warning

1. You can buy a tester called "Disc Brake Pad Gauge" to know precisely (the best thing to do is to remove the wheel)
2. If you have aluminum rims, with plenty of space, you can see approximately by eye (see even use the tester without dismantling)
