The light wasn't on before I replaced the pads yesterday. While I was bedding the pads the light came on. As I understand it, my only options are:

1) Installing new sensors from the dealer
2) soldering the wire together to recreate the loop.

Any other choice? Thanks.

Maybe you installed the sensor on backwards. It can happen, done it once before.
Make sure the tip ends of the wire are pointing to the brake pads.

If yours got ruined during the un-install, just get a new one. $15-$20.. ?

You forgot option 3:
3) Install new sensor from Rock Auto

Last time I checked Raybestos had some for $15-20. Visually inspect or check the resistance at the sensor plug using a multimeter to find which loop has been cut. You may need only 1 - in which case it's half price.

If it was me (and the sensors weren't destroyed) I'd remove them from the brake pad locations and zip tie them out of the way so the light never comes on again. I just replaced my rear pads as the sensors were just starting to 'touch' (no light on yet). But I still had a LOT of life left on those pads. In the future I'll just check the pads myself, don't need the idiot light to tell me I need pads 20,000 miles before I do.

Arcturus

Agreed. In my opinion this is a gimmick. Just solder the wires together, tie them up and out of the way and check the pads periodically. My main criticism of the LS is that most of the systems that fail are expensive gimmicks that give little to no added value.

We do our own repairs, but for 80% or more of owners that don't, how is a sensor that monitors wear a gimmick? Owners don't pull wheels off once a month and check pads. I think is a perfectly better option than the squeal sensors that are just annoying.

Arcturus

If owners don't have a brain and expect their brakes to last forever then I guess it is okay. Normally you would expect people to periodically check them - at least that's what people did before sensors. Once every 20,000kms would probably suffice. Also seems kinda stupid to have non re-usable sensors that are almost the price of a set of pads - at least from Lexus. I don't see the advantage personally.

The front & rear brake wear sensors are available on eBay for less than $10/each. OEM is absolutely not necessary for this part.

The wire may be damaged at the rubber thing where it attaches to the pad. Don't buy from Lexus, it's very expensive.

They are about $15 each on eBay. I recently bought me a rear one, as the old sensor was stuck onto the brake pads and I couldn't remove it.

In addition to making sure that the sensor is not worn through (has an open circuit), you need to also make sure it's not grounded somewhere.

Not only because these sensors are super cheap to replace, but it's good practice to always have your car set up the way it is supposed to.

It makes things easier for the 2nd owner. Many times have I found the previous owner cutting corners on lots of cars I owned. It's just frustrating. It's not clean and it just makes every job a surprise.

So, do yourself a favor and slap a new sensor on that pup.

So, King ... why'd you changep the LS's fine stock intake with that Injen 'cold' air intake or any other mods you have? Don't you like things setup the "way they were supposed to be"?

I am actually in a self debate to put it back on

Misunderstood what I am trying to say, invalid analogy brother campisi.
I didn't take the stock intake remove it, and zip tie it to the fender........
