Got a break wear light

[Pdwight]

They are also 4 months old, I am just going to replace all the sensors and Ohm them out after I get them off. I will post the results...but it may be a week with my work schedule right now

Thanks everyone

Dwight

Likelihood more than one sensor is bad, is only if they melted like Steve stated.

Buy one sensor, unplug, and plug in the good one. no need to route the sensor, turn key on on the car and check to see if light is off. If it is off, you found your sensor. if not plug old sensor already routed back in, and go to the next one and repeat.

Well I sent an email to ECS telling them you guys say their information is wrong. I'll let you know what they respond back with. I also gave them the link to this thread. Maybe they will respond directly to the thread?

If I'm wrong, then I'm wrong, but this is what I have read from a very well respected Porsche parts seller. I didn't just pull it out of the air.

Think about how thick a pad is. Then imagine a rotor thickness. There's no way a pad can wear about 3/8" into the rotor. Maybe with a paper thin pad and a rotor way past the limits.

See my above post.

EDIT: They said even with new pads, not paper thin.

Wouldn't be the first time a parts supplier had misinformation. Pelican had on their website replaceable plastic spark plug tubes for 2003 and 2004 Boxster. Those years of the Boxster do not have replaceable plastic spark plug tubes. I emailed them about it. They checked into it, found that was true and then sent me a thank you email for letting them know of the error.

Is it possible for a rotor lip to wear into a brake sensor? Yes.

Is it likely a rotor lip to wear into a new brake sensor in 4 months when a new pad is over 10mm thick? Not likely.

Is it possible Dwight's rotors are that bad off that he just put new pads on some rotors that were totally toast? God I hope not!

Then why was I told I was wrong right off the bat?

They say even with new brake pads.

Dwight is a very intelligent person, but this mistake could easily be made. After 4 months the rotors finally cut through the wiring.

Trying to imagine how bad Dwight's rotors can be....

I don't think they would have to be that bad to cut through the wire. Not sure where you got that picture from. Probably someone racing the car and overheated the rotor really bad.

Again, why was I told I was wrong right off the bat?

I used reasoning and what I have read to deduce the problem.

Nothin' wrong with that. Its obviously a 'slotted' rotor.

KRAM, pull one of your wheels off and get a look at how the sensor wires run. If the rotor with a new pad is cutting the sensor, something isn't installed right. I thought that *maybe* a rotor could be so worn that the edge might skim a sensor, but a new pad has a thicker surface than the rotor has depth.

Here's a couple images that may or may not help the discussion.
New and old pads:


I just happened to have some parts laying around and set them together (not fully installed). You can see how the worn pad (lower) lets the rotor cut the sensor. Upper-new pad it isn't going to happen.


Hopefully that is not just more confusing.

We're looking at a car that had just the pads changed 4 months ago, the rotors we're not sure of their condition. So 4 months later he has a brake wear light come on.

Deducing what I think would be the issue, through what I have read and the amount of time it took for the brake wear light to come on.

I have a very reputable Porsche parts seller that says even with new pads the rotor can cut the wire.

Grinding, pulsating and a lack of stopping power are signs of a bad brake rotor. If your brake pads have worn deep into your rotor, the lip on the outer edge of the rotor can cut into your pad wear sensors, causing a brake pad warning to appear in the instrument cluster - even if your brake pads are new. Rotors should be checked every time you service your brakes.

Do you think it's wise to call me wrong right off the bat?

I look forward to ECS Tuning's reply on this. I hope they respond directly to this thread.

From what you read, what you deduced makes sense. I can picture how a lip on an extremely worn rotor could cut the sensor. Looking at the actual brakes, I don't think it's very likely.

I'm definitely following what you're saying with new brakes pads.

I want to know what ECS Tuning has to say about their information on rotors cutting the sensor even with new pads.

Great! Now there's two of them!!!

Can I get some thoughts on the moon landing actually happening, or maybe Bigfoot?

Cannot happen with a new pad. There's even a pic that shows thicknesses of both.

It's the small bird carrying a coconut thing. It's not a matter of the weight of the coconut.......or the amount of flapping it can do. Physics.

Offer stands. $100 to show me how a worn rotor can cut through a sensor wire PROPERLY installed in a new pad. I've got all these parts at my shop spare. I'm glad to dissect or display them to help prove how this can't happen. Sounds like they are selling rotors to folks who just need pads.

"Wear indicator came on?? Sounds like the worn rotor cut through the pad wear sensor in those new pads!"

I don't think I was quite understood by Tim. Here's a clarification:

"From what you read, what you deduced makes sense. I can picture (in my mind) how a lip on an extremely worn rotor could (in theory) cut the sensor. Looking at the actual brakes, I don't think it's very likely (on par with the possibility of Bigfoot existing)."

Here's a picture that may, or may not help:

OMFG!!! Thanks for that Healthservices!!!I can't stop laughing overtime I see that!!

Geez dude, you really have a reading comprehension problem. 78F350 said and showed a picture that a new pad would not let the rotor cut the wire. I said I'm following him what he is saying about the new brake pads. That means I understand what 78F350 is saying.

I then went on to say I want to know what ECS Tuning has to say about their information on rotors cutting the sensor even with new pads.

Now calm down, let Dwight find out what caused the brake wear light to come on and ECS Tuning time to reply.
