brake wear sensors

for some reason it came on(not worn out yet) and I want to replace sensors...

when i looked at the rear, i couldn't find where the connector ended up...sensor wire is really long(4~5feet)

can ya show me where the sensor connectors are?!

im just gonna connect them and tape them somewhere where I can't see em. I do visual inspections so often, i don't need wear sensors

So then why connect them? Just leave them disconnected. They will never go off.

Because they tell you when your brakes are out? It's one of those "I drive a BMW and are lazy features" I dont see why if you have it why you wouldn't want to use it. The sensor should be plugged INTO the brake caliper. At least that's how it was on my E46, basically as it wears it gets to the point were the pads dont cover the sensor anymore and the rotor wears away a little of the sensor and it trips the signal.

But these sensors are notoriously faulty and cannot be relied upon. They have already been replaced under warranty on my car for constantly going off while the pads were still quite healthy. If you're out of warranty, and these are being a nuisance, and you're mature enough to check your own brakes (or just use pads with wear strips built in) then why not?

I agree with Reach, sensors are just primitive little trip wire mechanisms that aren't really needed.

If you're someone like who tracks the car regularly and does their own maintenance, checking brakes is part of the regimen and the sensors aren't needed.

I drive the BMW cuz I love the performance, not cuz I'm a snob who can't check my own brakes. But more power to them for supporting BMW's dealerships by paying for overpriced repairs. Personally I can't afford it so I'm forced to get my hands dirty.

I've never had a faulty signal from my brake pad sensors. I had one pad that was wearing improperly on my E46, that pad was dead well before the rest and it was a rear pad as well. The sensor went off, I checked it and surely enough it was definitely time to replace it. Its not a matter of "are you mature/smart/mechanically inclined enough" to check it, its just one of those things that if it isn't broken dont mess with it. That's how I feel, I haven't any problems with it on my Z since I've had it, of course everytime my wheels are off I check the pads but that doesn't mean I'm going to go rip them out. Sure if they went off and it was false or it went out and I replaced my pads then I'd think twice about putting them in.

yea im not gonna replace it. I do my own maintenances and check em very often.

i just stuck a elec tape behind the cluster so i don't have to look at the light lol

no sense in going through trouble to replace.

i do have two sensors(brand new) for sale though(got em with my brake purchase)
