After having my front weels off for the first time on my skoda yeti, I noticed the brake pad sensor cable that's meant to indicate worn brake pads has been 'crossed off' and not plugged in. The socket is disconnected and not attached to anything and sits neatly tie wrapped to the other cables. I know the pads are brand new so I'm not worried they be worn out and I have no wanrning lights on my dash board.

My only query is; could this situation have any impact on the function of my ABS/EBD etc? I noticed all the wires are quite close together and don't want this one socket breaking the whole circuit for my braking system and stopping other things from working

To enable the brake warning light to stay out i'm sure the circuit for the wear sensor must be shorted out. So i'm a bit confused as to why the warning light isn't up if there is nothing plugged into the plug unless they have shorted it out elsewhere or disabled it completely.

 

I can't see how a the socket tied up is going to damage any of the other cables so I wouldn't worry. And if there is damage, its pretty easy to just use some 4 core wire, some soldering and heat shrink to repair it as I have done that in the past

Thanks for your reply. Ye it looks as though it has been shorted out in order to get the light off the dash board. Doing this wouldn't have any impact in the ABS would it?

Don't brake wear sensors usually work by creating a short-circuit when the wear limit is reached, thus triggering the warning?  If so, an unplugged sensor won't report a fault and won't light up any lights (and won't require any short-circuit jiggery-pokery).

Correct - they're open circuit until the pads wear low enough that a bit of metal touches the disk. So if you fit aftermarket pads that don't have wear indicators, just tie the connectors out the way.

That is my understanding as well.

 

PO - Is there any obvious reason why they weren't plugged back in?

 

Edit: muddyboots has just answered that one!

 

Not a big deal anyway as worn pads should be picked up as part of routine maintenance/servicing as in the good ol' days!

I'd could be that although the pads fit the Callipers there not actually the correct ones for the Yeti, I've had pads before which were listed as correct but had the wrong sensor connection. Check the male/female connectors and see if they are a different configuration

yes you can see it in the picture attached. I think it does just look like they are the correct pads with the wrong sensor

Some aftermarket pads simply don't have wear sensors.

Just me, or does that caliper look very very dirty or corroded?

The cable in the picture not being attached to anything wouldn't have an effect on the ABS, EBD etc? Yes the caliper is very mucky due to where I live/work haha

No, they make a circuit and then break when the internal wire of the pads is broken. Hence why you have to short it out to keep the light off. This is a fail safe design so any break in the cable or pad brings up the light

 

Unless they have changed round the way it works on the latest models.

 

and no, it has no effect on the ABS sensor.

As SuperbTWM (I was born in Ponte by the way ) said, ABS sensor is in the hub so no effect from the brake pads, they probably didn't realise they weren't exactly the correct pads until after fitting and couldn't be bothered with the hassle of removing, re-ordering and refitting!

I'm running Tarox performance pads on the 150ps 4x4 Yeti which don't come with a sensor so it won't effect the way anything works.

Thanks all for your comments and time

I stand corrected

I was thinking of other cars I've had where there was a single wire.

Now you've said that, I do remember when I last changed pads on a Passat, they were indeed 2-wire and I had to short them out when I fitted uprated pads with no sensor.

I'm running EBC Yellows on the Yeti, and I can't remember if they had a sensor or not - they must have done I guess as I didn't have to short anything out.

I've found the best way to do it is to cut the socket off the old pads and solder the wires together and plug that in. That way you stop moisture and dirt entering the plug so you can use it again if necessary.

That's exactly what I did ☺

Just replaced disks and pads on my 2012 Yeti, and there's no loom on the car to the brake pads. Not sure if all models had them fitted, as the old pads didn't have a cable attached..

Odd, as all Yetis can run variable servicing it should have had one on the n/s/f caliper.
