Brake pad usage

m1bjr · 08-11-2011, 07:03 PM

335i:

348x30 F
336x22 R

Thinner - less material.
The 330 rears are the same as the 335i though IIRC

Even so, those dimensions don't tell the whole story; the rear disc pad area is much smaller, despite a similar diameter, because of the space taken by the handbrake hub. I still maintain it's a bias issue.

Is this not to do with the 'anti-dive' setup BMW talk about on the E9x? As you say, xenon, almost certainly down to rear braking bias.

Yes, could very well be.

In all my previous cars I've gone through front pads at 8-10K with normal road use. Rear pads usually lasts twice as long. I doubt the fake electronic diff will effect rear brake pads that much...unless your doing donuts all day

It only had 3k miles on when I bought the car so doubt it mate.

From the get-go you are assuming the electronic wear guide is accurate.
It isnt.
Have you measured the pad material remaining?

Are you sure about the electronics ?

Reason I ask is I had my MOT today and the guy doing it said the rear pads are 80% gone but they should see you through the winter. Idrive service indicators show 16000 miles left on rear pads.

Will have a look myself in the next few days but it does raise the question in my mind...
