How long do oem discs last ?

[Ross M]

quick question hopefully quick answer.

and i know itll be rough and driver dependant etc but need a rough idea ...

 

[alexbleubolt]

well my rear discs have lasted 76k - look a bit s**t now

 

[Fred@BTM]

30-36K on average is what i see

 

[rwaterman]

Does that apply to front and rear or just the front ones Fred?

 

[Fred@BTM]

both, we have some customers that have destroyed both the fronts and rears in 6K on a new car from the dealership! (no names mentioned )

30-36K is my approximation on an average road user with a few track days thrown in

 

[rwaterman]

Thanks Fred. Do you know the minimum thickness a disc gets to before it needs changing? Is it the same both front and rear?

 

[Fred@BTM]

no different

front min thickness is 21.8mm
rear min thickness is 7mm

minimum pad thickness (inc backplate) is 6mm

 

[DrR]

mine are just about to hit 53k

 

[Graham Gooch]

I've just changed all mine at 48k

Wish I'd done it ages ago, brakes so well now.

 

[Ross M]

hmm

 

[Dubai182]

Mine lasted 45k but a lot of motorway miles in there with little braking. Actually had metal braking on metal the last few days, was erm, interesting.

 

[bartebk]

Mine lasted 12k,road use only,just been changed under warranty.
Heavily pitted apparently

 

[DrR]

Ok now i'm worried, as mine have done 53k and look fine?

 

[Englebert]

I had literally bits missing from the disc at 36k, not done a trackday in its life.

 

[DrR]

Oh well i'll be calling mr yozzasport for a service in 3k time, so i'll see what he says.

if the pads start grinding when braking how long till the discs are fuzzled ?

Your disks are already fgone if that happens should get the pads and disks changed imediatly if there that bad.

 

[Ross M]

lol thought so ... they dont work anymore. damn that footballer !
getting it done tomorrow.

 

[Evil Ally]

18k front and back both shagged, 4 track days though. Rear discs are so expensive :dapprove:

 

[Ross M]

my rears better not be shafted ...

While we're on topic in a way. How long on average would a set of Ferrodo crossed drilled? and greenstuff pads last. Bought the car with them newly fitted and im clueless in this topic.
