!!Urgent..question on Porterfield pads!!

So I dropped my c230K off for the A service today which included putting some Porterfields on the front and rear. Talked to the tech this afternoon and they're going to be holding it overnight waiting for the new center vent piece to come in. Here's my dilemma: new pads went on fine but according to him there's no where to put the brake pad monitoring piece which means everytime I start up the car it's going to come up with a message that that new pads are needed. I know plenty of other people in these forums have Porterfields so I can't be alone in dealing with this. Any thoughts on either how to attach it or how to disable the message? Many thanks in advance.

Most people just tape the pad wear sensor somewhere out of harm's way. Remember, you will have to visually inspect the pads for wear. When MB releases the OEM pad backing plates to the aftermarket, this will not be a problem.

Must be the same mechanic as mine. I told them ahead of time to tie wrap the sensor wire out of the way. So they removed it and spent an hour figuring out how to make the brake light go off. This is all while I waited and watched. After a while I had to go on the floor and see what they were doing.

Thanks for the quick response, any ideas on how they disabled the light would be -very- much appreciated.

Maybe I didn't make myself clear. The light does not come on if you tie wrap it out of the way. It only comes on when you remove the sensor wire. SO DON'T REMOVE THE SENSOR WIRE!

Please, please, please tell me you are kidding.

Because if you are not, then your "mechanic" (which as I recall is/are dealership mechanic(s)) are scary dumb.

Remember, these are the same mechanics that failed at doing an oil change, surely replacing pads was beyond their skill level.

Ummm, if the answer isn't super obvious to you, you are not much an an "import tuner."

Brake pad sensors have worked on the same principal for at least 20 years now. Pretty basic stuff.

Pad wears down, rotor wears down and breaks the wire in the sensor, creating an open circuit and activating the light.

It doesn't take a genius to figure out when you disconnect the sensor, you are creating an open circuit. Thus activating the light. Auto Mechanics 101.

For a dealership "mechanic" to scratch his *** for an hour trying to figure this out is shocking. It would be funny if it weren't so sad.

No wonder so many people have to take their car to the dealer 5X to get basic problems fixed by these parts monkeys.

SoCal240, I'm shocked that you of all people would stand down and remove the word "cabriolet" from your signature from all the pear pressure on this board.

And it wasn't a dealership mechanic that scratched his *** for an hour, he had someone else look at it to, so it was 2 dealership mechanics scratching their collective asses on this one.

Mmmmmmm, pear pressure.
-Homer Simpson

I didn't take it down because of peer pressure, I took it down because the vast majority of people didn't get it. That was evidenced by the most common reaction being a request that I post a picture of my "cabriolet."

2 mechanics is 2x as shocking. Even if you knew nothing about how a brake pad sensor works, you'd be able to figure it out in 5 minutes if one had an OUNCE of diagnostic skills.

It goes something like this: "Car came in, brake light was not on. Brake light now on. We did 2 things: Swapped the pads and disconnected the sensor. The pads are simple pieces that are not connected to the electrical system in any way. That leaves [______] (Fill in blank)."

It took those geniuses 2 man-hours to fill in the blank! Wow.
