The 2010 brake pad warning
The 2010 brake pad warning uses wear sensors placed on the left front and right rear wheels that are basically loops of wire embedded in the sensor which are held at a certain distance off from the brake pad backing plate. As the brake pads wear, the sensor wears away from the abrasion from the brake rotor, until the loop of wire is broken.
The sensor has two pins in the connector, and when new, will show continuity between the two pins. The sensor is a two stage type of device that is supposed to provide an early warning indication when the direct loop is cut.
Further down in the sensor is a 400 ohm resistor loop, which can then signal to the warning system that the pads are approaching the service limit. As the pads wear further, the sensor then wears away the connection to this 400 ohm loop, and now the sensor is completely open circuit, triggering the red dash warning with the car on the lift.
If the pads were replaced before the sensor was worn away, the sensor could be reused. Just remove the old sensor carefully to avoid fracturing the body. The sensor needs to be removed before removing the pads to prevent damage to the wires.
While the sensor could simply be connected together at the two wires to enable reset of the warning light, it's good to have the warning indication. Not having the replacement sensor on hand, I just used the worn sensor as a substrate, soldering a new loop on, at the same level where the indicator went off. This should provide the pad warning at the same amount of wear, although without the two stage warning- it'll go immediately to the service warning once the loop is broken. There didn't appear to be any prewarning indication anyway, so they may not have implemented this feature in the MINI, instead only showing the indication when it went to full open circuit.
In that case, the retrofitted loop of wire should work the same.
-Procedure for resetting the service indicator after replacing the pads and restoring the pad sensor wire loop:
-Turn ignition on without holding down the brake pedal, (no need to start)
-Cycle left stalk button until it shows set/info
-Press and hold button until it shows CHECK-INFO
-Press once until it shows SERVICE-INFO
-Press the right tach button (trip reset) for 10 seconds until display changes.
-The brake pad warning should show up in red, showing in this case, "mls - 200" indicating the car was driven 200 miles past the tripped point.
-While on that display, press and hold the turn signal stalk button and it should show RESET.
-Release button, then press and hold button again, a timer clock will show up, as a brief confirmation period to let you change your mind and cancel the reset.
-After the clock cycles around, the reset is complete, provided the two pad sensors no longer indicate an open circuit. If it doesn't reset, the pad sensor circuitry is still detecting an open circuit.
