Minimal brake pad thickness?

Does anyone know what is the minimal pad thickness, when one may ask for warranty brake service? I understand that the brake light goes on when only 2 mm is left. However my new rear rotors (recently serviced) have some kaballah-numbers stamped on them (4mm20mm or so) that may suggest that 4 mm is the number.

Thanks.

3mm is minimum pad thickness according to the TIS. However, many dealers nowadays won't do brake service unless the sensor is broken and the light is on.

The number stamped on the disc is 20.4mm, which indicates the minimum thickness of the disc (shown in Euro format 20,4 mm).

The brake sensor will light up when the disk is down to about 1-2mm. Some dealerships will change te pads even though the indicator light is not on.

How easy is it to break the sensor?

Dunno.... never tried it....

But from what I'm told, they actually test the sensor... they'll actually look to see if the sensor would really have been broken given the amount of pad there.

Sad state of affairs indeed...
