If you're talking about brake pads that have an electrical connector..
the warning light comes on when the pad is so worn that it allows the electrical connector to earth via the disk .. hence the warning light.
Fitting new pads will not cause a warning light on your dashboard. No reset required.
Sounds like you need new brake pads , when the pads get worn it triggers the warning replace the brake pads reset the computer this should fix the noise and the warning lights.
If this is a brake warning light,it comes on to warn you brake pads are low
If pads have been replaced,the sensors are faulty/or fitted incorrectly
Check your owners manual to check warning light meaning
The pad wear warning shouldn't have to be reset. It will only
illuminate if it actively sees the sensor circuit grounding out. If the
all the pads/sensors have been replaced properly, it should
automatically disappear.
Maybe it's possible there's another problem. Fluid level is ok? No air
in the system? All the sensor wires are routed properly?
Hi Chris
Is there plenty of fluid for the nrakes? they should have little wires coming from the brake pads , normally once you have replaced the pads this light would go out automatically.
As the brake pads wear, the brake pad wear sensor contained in the brake pad contacts the brake rotor. This causes the sensor to fail. When a pad wear sensor fails it opens the ground circuit of the pad wear warning light system causing the pad wear warning light to illuminate. Perform normal brake service to correct this condition and be sure to replace the brake pads with pads containing wear sensors. Once the brake pads and wear sensors are replaced, reset the brake pad warning system by turning the ignition switch to the "on" position. As long as continuity to ground exists through all the brake pad wear sensors the system should reset and the pad warning light in the dash will go out. If the pad warning light does not go out, a check of the pad warning circuit for an open circuit condition or poor ground must be performed.
I dunno if this will work on your BMW, but on my BMW Z3 and M3, it was....
Turn the ignition key to position 2, but do NOT start the car. Wait for
about 45 seconds and the brake warning message will be reset.
If it doesn't reset, then the brake sensor was damage. You will need to replace the brake sensor. It sounds like you replace the brake right after you saw the warning, so the brake sensor should be okay.
