Disc brake pad thickness.

Anyone able to tell me the thickness of the actual pad friction material, please?

That's excluding the metal backing plate of course.

I'm trying to calculate my pad wear rate as I don't want to change then unnecessarily early.

I usually change them when they're down to around 2mm, and they are just a tad under 3mm at the moment, and I can't remember what thickness they were new.

I believe that under 1.5mm is an MOT fail, but if I left it that late I'm sure I'd get brake fade in the Alps.

Thanks,

Singvogel.

am pritty sure mines was about 13/15 mill thick when i fitted mines mate

It says in your sig, that your not using standard pads. I'm assuming that is still true, in which case i guess if you cant find it on the manufacturers website. Then it would be easiest to buy a new set (your going to need them anyway eventually), measure them, then calculate it from that. Would guarantee your readings being correct, allowing for variation in the different methods used for measurements and the skill of the person taking the readings, since your taking both readings.

Also MoT is 1.5mm (fail ref in the manual is 3.5.f. and states: f. a brake lining or pad insecure or less than 1.5mm thick at any point)

I'd change pads at 2mm. Lets face it , they've seen better days at this point.

Buy a new set ready for the next change and measure em, now that's not rocket science is it.

At under 3mm and for the small price of pads & your safety I would change them before you go :rolly:

Thanks for the replies guys.

Vissie - Yes I have EBC pads at the moment and they have lasted well, but they are too pricy as I can get 2 sets of Pagids for the same price as the 1 EBC set, which doesn't last twice as long.

Soloby Rob - Yes, it's not rocket science to measure a new set, but I wont' be able to get to the nearest Eurocarparts store until Saturday.

I was thinking that most brands would be about the same thickness which I was guessing at 15mm, and just wanted to check if I was wildy out.

Thanks,

if you buy cheap ones they are about 5mm if you buy good ones they are about 7-8 mm i would change them if you are going that far singvogel there is no garages up in the alps is there ? i wish i was going up there in my Freelander just to save fuel and come down on the slopes LOL

my Pagid pads were 8mm new

Thanks for that Freelaner.

8mm makes better sense.

I've just ordered a new set of Pagid brake pads from EuroCarParts.

Cost £22.64 inc. VAT and free delivery.

I'll get them changed this weekend hopefully.

Am I right in thinking we don't have low pad-wear sensors?

Cost me a packet on my Sprinter as I waited until the warning lights came on and needed new sensors as well as pads - those rascals cost more than the pads.

These EBC pads have only lasted about 35K miles - exactly the same as the OEM pads - so not worth the higher cost.

At 110K I've gone through 3 sets of pads and 2 sets of discs.

Must be all the mountains and Alpine passes.

The EBC discs are still in great condition though - the LR ones rusted like hell, and developed wear grooves, and a deep lip at the edge of the disc.

Good to know about the EBC discs S,

Mine are grooved with a rusty lip (bigger on the inside). OEM pads I would say as all the servicing was done by local dealer.

They bite well when you hit the pedal, but will probably cause more trouble that it's worth when it comes to new pads being so uneven.

No pad sensors.

They dont even have them on FL2.


On the upside , if you have a torch you can just look through the alloy

The reason for disc ware is that the manafactor is no longer able to use the dreded asbestos so now it is abrasive stuff they use and thus wares the disk out

They have reeds instead of sensors these day's which are suppose to squeal when the pads are down to 2mm!!

Padgid all day....... I will fit nothing but. they don't suffer from brake fade (unless of course you are very heavy on the brakes) don't suffer from squeal and above all last the test of time and come with plenty of material from new......
