Brake Wear Sensors


 Share

Recommended Posts

Hello. My brake wear sensor warning popped up the other day. I have decided to replace all the pads and the disks as this is something I have been meaning to do for ages. The disks are grooved and at least one is slightly warped. 

My question is this. Is there a brake wear sensor on every wheel? Or is one per axle? 

And...is the sensor the same part number for both front and rear? I have found replacements for £10 each, so not massive money, but don't know how many to buy. 

I am also getting four shiny new Pirelli P Zeros fitted at the same time, so not a cheap month, but it will be very satisfying to know it is all done. Nothing nicer than seeing your car with new brakes and tyres.....

Kind regards. 

John

are these Pirellis the best comfort wise for your car then ?

I only ask in a circumspect way coz the Pirellis I had on my Honda Legend, whilst brilliant wear ..  never wore out ........  were goddam not comfortable a ride ........  thank god they did wear out eventually and now with Falken, which, as on my old Ls400  ............... perform very well in all respects .........  and not that expensive either

just a thought !

Hi Malc.

Oh mate, I have spent countless hours looking at tyre reviews lately and have gone around in circles (pardon the pun).

I value comfort and quietness in tyres the most, and the Pirellis seem to have those qualities according to reviews. I guess I won't truly know until they are fitted. 

I wish tyres were like shoes, where you could try them on before you buy.....

then why not ( or maybe you have already ) asked the Forum Ls430 Members here about their thoughts !

It's a big big spend and will last many years whatever you decide 

and Brake Wear Sensors, well, on mine they have now ( my indy tells me ) been cut off and taped appropriately ...  they always showed as " worn " when there was mountains of wear left .  so infuriating tbh .  they just had to go

There was always plenty of wear left until the next service but one, when that gave enough time to prepare for discs, pads whatever at that next due service 

I've never missed them, just avoided the red warning light, and never had issues with changing the necessaries

There is a wear sensor on each wheel so 4 in total, different part numbers for each one but at over £100.00 each from Lexus I would stick to aftermarket.

If the sensors are OK I would leave them.

I have Pirelli P-Zeros ( 245/45/18 100Y) all around on my LS430, when first fitted they sounded like I was on a gravel track but quietened down after a few miles and are now almost silent with great grip and little wear.

Hi Malc.

That isn't a bad idea. I find tyre reviews really confusing. So much is based on peoples expectations and what they are replacing. Even the professional tests differ in findings, and then you need to be aware of the date is the test, if the tyre is XL or not and the actual version of the tyre. 

I will put something out and see what I get back!

Cheers. 

John.

Thanks Steve. I will save the sensors of possible or could opt to bypass them.

Are those Pirellis XL (extra load) - I think this makes a difference to sidewall stiffness....

I have only seen 2 wear sensors, one for the front and one for the rear. I stand to be corrected though but for the 95 LS400 I had and current 98 LS400 there were/are 2 wear sensors.

I may have to try the Pirelli P-Zero PZ4's next time.
I currently have the Goodyear Eagle F1 Asymmetric 3 which are supposed to be 69dB (A rated) for noise, but are actually pretty bad noise wise compared to the Avon ZZ5s (70dB) that they replaced.
Noisy enough that I won't buy them again. On that crappy section of the M25 from J8 to J11 the noise was so loud I actually had to raise my voice to speak with the missus. :laughing:
Nobody seems to be making quiet tyres any more. They all seem to be 70-72dB now with very few below that.
I guess they are focussing on "efficiency" and actually want noisy tyres because pedestrians can't hear electric cars (and Lexus LSes) coming.

I know my 1994 had them on each wheel but whether this was an import thing or just the earlier models I’m not sure.

Just looked at epc data and it shows 4 wear sensors for the mk2, that is doing things properly! A wear sensor per wheel when normally it’s one per axle, impressive.
