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.
They should reset themselves or "go off" by themselves. Its possible you have instead a short or broken wire that was giving you a false indication in the first place
You can reset this fault code using the buttons on your dash - you don't need a dealer to do this. As you already know, you need to replace your pads and the brake wear sensor - this is a sacrifical item. Once this is done, do the following:- Using the buttons on your dash - there are 2 - one on the LHS (Trip reset) and one on the RHS (In between Tacho and temp gauge)
*Press and hold Right button and turn ignition to first position (I or Accessory)Display should show "Check Control OK" then a short time later "Test Nr.01"*Press the Left button and you should see the car info in the display. Add the last FIVE digits of the car identity number together (NOT all 6!) to get a unique ID for your car.*Press the Right button repeatedly until you see "Test Nr.19"*Press and hold the Left button until you see the number matching the unique ID you calculated, then release.*Press the Right button to select this.*Press the Left button repeatedly until you see "Test Nr.21" - Reset All Defect Codes*Press Right button to reset the codes.Done!
yes...it's as same as the Hand Brake Sign light. if it's NAS Spec's then no sign. only Hand Brake Light will remain on. but you still will be getting a message in the message center says Check Brake Pads
it cannot be reset. there is a sensor on one of the brake pads which has a connector on it and the connector plugs into wires on the car. if the pads that are on it don't have the electrical sensors in them, cut off the end of the connector on the vehicle and connect the two wires. this will turn off the light. don't worry, no damage will be done by permanently connecting those two wires.
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.
brake pads are the ONLY way to stop you going like 30mph+ when you hit like a wall or person or like another road user & if you do crash YOU will be totally at fault for having an unfit car. The best way to get the lights on your dash to go out is to fit new pads. The lights show that the time when the brakes WILL fail is drawing very near, it is stilll up to you to get the pads changed. You will not get any further warnings from your car prior to not being able to stop at all thus causing endangerment. You will be shocked at just how bad they were when you feel the new pads.
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.
Check the wires that are going to the brake pad sensors.Some shops will install pads that don't have the sensor connections on them, causing this light to stay lit.
