One tip, from my own recent experience - if the existing wear sensor is still good, and you intend to re-use it with the new pads, make sure when you unclip it from the old pad that all of it comes off together. There's a small brass-colored spring clip around the phenolic resin "nose" of the sensor, that serves to ensure friction fit in the notch on the pad. When I replaced my only-slightly-worn rear pads and unplugged the sensor, I failed to notice that this clip stayed behind in the notch. Later when I'd installed the new pads, and found that the sensor didn't want to fit tightly into place, I noticed that the sensor looked "wrong". Checked the old pad - fortunately before I'd thrown it away! - and sure enough, the spring clip was still in place in its notch. Popped the clip off the old pad, pushed it over the nose of the sensor, and then was able to firmly install the sensor into the new pad.
Brilliant video, thank you. Did this on my wife's LR4 and it sorted the warning message out, whoever had replaced the rear pads hadn't replaced the sensor too. 👍
For what it's worth - much of this video is also applicable to the wear sensors on the Discovery 5. Just did the front & rear pads and sensors on my wife's 2017 HSE this week, and this video was very helpful. Thank you @Shiny Fast & Loud!
Literally the best video on the sensor! Thank you for actually showing the sensor placement! You are awesome!! Everyone else just said "between the pad & rotor" That was incorrect!
Thanks for this. I took on the project without seeing this video and now that I’m done, and frustratingly so….. I find this!!!! Great video, wish I had seen it before I took the project on.
Excellent video - I was wondering how the sensors worked. This has shown me that the preface is by physical wear, whereas I was expecting something like width of the disc calculations. A very primitive sensor indeed. The upside is that if you don't wear your pads below (say) 30% then you don't need to change your sensors. They are disposable but only after they've been worn down. I'll bet many mechanics charge for replacing sensors when they leave them in place and change the pads only!
Once the sensor comes on the wire circuit has be worn OPEN and needs to be replaced. How are you going to change pads before the sensor tells you? Take them off and guess? Then you are wasting money by changing pads too early. They will start to chirp if you ignore the sensor and keep driving. Most cases you are replacing the rotors so to get the most out of the pads just drive till they grind and replace then pads/rotor/sensor.
Thanks, very useful. Also worth stating that as your rotors wear, the tip of the rotor can cut through the sensor too. The pads may have plenty of meat left, but the top of the disc has a significant lip.
So the wear sensor wears and breaks the wire which opens the circuit = dash light comes on. So if the wear sensor comes on is the sensor broken at that point? Seems it would come on and stay on but mine flickers and some times goes off. It just started so I have some time before its metal and metal. So its impossible to save the wear sensor once it comes on and must buy a new on for each break job. Is it two sensor for front and back? or just one front and one on rear?
Yes, it comes on because the sensor is broken and by that point needs to be replaced when the brakes are replaced. There are only two on the vehicle....one in the front and one in the rear.
Hello. So I changed my brakes and sensor is not damaged. The light is still on after. Does it rest by itself or is their a processs. Thanks in advanced.
Best video I have seen for this procedure. One sensor is enough because it is difficult to only buy half a set of brake pads (for only 1 wheel)

@@ShinyFastLoud different wiring loom, maybe it’s because we have the TV / DVD. anyway all on now after some serious fiddling!
@@Himoutdoors glad to hear
Do I need to replace the sensor after replacing brake pads? Also would it reset itself or do I need a scanner to reset it?
If it is not damaged you don’t have to replace it and you do not need a scanner to reset it.
Very useful video, thanks 👍

Is there a sensor on each wheel?
There are only 2. One on the driver’s side front and one on the passenger side rear……at least on a North American model.
Dude, you need to listen more - he was really clear that there is one on the back, one on the front
@@deej99 Dude you need to re listen more, He voice was garbled near the end when talking about sensor location.

Thank you brother
How do you reset the brake light?
thank you. very clear
You are welcome!
Great video
Glad you liked it
Sensor on the same side uk which is our passenger side your driver.
thank you for confirming
Thanks, great video!!!!!!!!!
Glad you liked it!
😮😮
It doesn’t look like this on my 3.0TDV6 2010. Real PITA to Acess😊
