Brake pad light still on after pads were replaced.


if you didn't replace the brake pad wear sensor, you wont be able to reset the light. if you did and it still doesn't reset, you need to get into the maintenance system with a scanner, (your local garage should be able to do it) and reset the brake pad wear counter

Brake pad wear indicator light does not go off at the dash after changing rotors brake pads and the sensor in the front wheels all pads and rotors and the sensor is ok at rear. the vehicle has only 30000...


Did you change the sensor? if you did, do a battery reset (disconnect for 10 to 20 min.).

Obviously the wear sensor has made contact with the rotor and is already damaged. You're not even suppose to resuse the wear pad sensor if its worn or damaged anyways.The way how the sensor works is that it must make contact to the rotor to complete the wear pad light indicator circuit. There is no mentioning that he replaced the the wear pad sensor with a new one.

But if one did replaced the wear pad sensor and the wear pad indicator is lit up, the way to reset it is to leave the key on in ignition switch #2 or #1 for about 30sec. turn it off and its reset.

Its possible that you forgot to replace the brake light sensors. They are about 15 bucks, and have to be replaced in order for that light to turn off. You can either get them from the dealer where they'll likely charge you 3 times as much, or you can go to http://www.turnermotorsport.com and get them there.

You have to reset the light by leaving the ignition switch on position #2 for about 30 sec. turn off the ignition and start the engine up and see if it goes out. I recommend buying a new wear pad sensor as well because now light will lit up when you're way below spec (less than 3mm)

Also, you could try with this procedure for one E39: Turning off the Check Brake Linings warning on the Instrument Cluster...
- so you've just changed the brake pads on your E39, along with the wear sensors. The old sensor(s) needed replacement cause you waited a bit too long before changing the pads, and wore through the sensor(s), turning on the BRAKE light on the dash. But wait, the light is still on? But there's a new sensor installed... what gives?!
- there is a procedure required in order to turn off the light/warning. With the ignition off, step on and hold the brake pedal. Now, while holding the brake pedal down, turn on the ignition switch to position 2 (just before cranking). Hold the brake pedal until the BRAKE light is off. Tada, the warning is gone and reset.

NOTE: This procedure worked on a 2001 E46 325i. It took about 15-20 seconds, but it cleared out w/o having to unhook the battery.

How to reset brake light after changing pads.


Hi Peters6709,
Sorry to tell you, but you need to replace the pad-wear sensors as well. They are the little trapezoid pieces that hang inside the tops of the inside pads. They should run about $10 each. Once replaced, disconnect the battery completely for about 10 minutes, if you have a stock radio keep the code handy.

Next time check the pads every 10-12K miles. I have been running the SAME pad wear sensors on my Z3 for the past 2 pad changes now after making the same mistake the first time.

Best of luck!

Brake pad llight on audi 2001 a6


In the past I had the same problem with new pads!
You must check up if new brake pads electrical wires are OK. Try as follows:
1. Disconnect only new brake pads wires from the vehicle electrical circuit.
2. Extract old brake pads wires from old brake pads.
3. Insulation wear cap from old brake pads wires.
4. Connect old brake pads wires on the vehicle electrical circuit.
5. Switch ignition ON and start engine.
Now the wear light must go off !
Please Rate my Response! Thanks!

Brake wear visit work shop. merc e270


Mercedes brakes are setup with a pad wear indicator on the pads, one of the four pads in the front should have had a wire attached to it ( as well as in the rear brakes if 4 wheel disc). If this wire is broken or was't re-installed on the new pads, this will trigger the light on your vehicle, if all the wirs are connected properly and in place i would suggest taking it to the dealer to have them take care of the light. Hope this helps

I replaced the front pads on a VW JETTA 2.5 and the check pads light is on. How can I reset the check pads light?


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 LIGHT


This light should turn off if you replace the pads with pads that have the indicator wire on them. The light truns on when you wear the pads down to the wires and the wires break and cause an open circuit that turns on the light. If your new pads have the wires and are installed correctly, the light should turn off by itself.
