Brake pad light on

I replaced the front brakes a year ago and instead of replacing the pad-wear sensor, I cut the sensor off and tied the two wires together, reset brake light - lights out - it works....
Now a year later same process for the rear, replaced pads, cut sensor off, tied the two wires together, reset the brake light - it goes off, but only to come back a few minutes later. I've made sure both the wires are tied together tightly. I can get the light to go off when i re-set it, but it comes back on shortly afterwards.
Any idea what's happening? Can I not trick both front and back sensors bt tie the wires together?
Please advise.

The $10 you spend on a sensor can save you the cost of a rotor, you know, and maybe even your life...the latter, is actually why there are pad wear sensors.

Put the sensors on.

Most cars, aside from luxury cars, don't even have pad sensors on the dash. I wouldn't go to the extent of saying it will save your life lol. I bought my E46 a week ago with the pad light on. I tied the wires together too, to bypass the sensor (as the previous owner didn't have sensors). They're a sensor at both front left and right rear. I connected both, and reset the light, and it hasn't came on since! So yes, you can bypass both. Most of us on here are DIY'ers anyway. We're all capable of taking a look at our brake pads every so often!

Good luck dude
