Brakes: "85% Front, 35% Rear" This is amount of brake pad that still there, right?

Why is there such a huge difference between the wear of on the rear verse the front brakes? Shouldn't it be the other way around?

Aprox. how many more miles between I have to change the pads?

I just have to change the brake pads, right? What high performance DUSTLESS brake pads would you recommend?

What good BMW brake shop would you recommend in the Vancouver area?

Thanks!

Ed

Wow, that is a strange breakdown of your pad-wear...

You should get Axxis dustless pads from www.justbmws.com ...should be around $70 for the entire car. I've been running them for about 20k miles and love em! No dust at all and my wheels look great!

Question Why?

I'm wondering why BMW doesn't fit those brakepads themselves on our cars? Is it the costs? Are they a lot more expensive than OEM pads???

Because when you hit your brakes the weight shifts to the front of the vehicle... thus the front brakes need to do more 'work' in order to stop the car.

If you ever get a big brake kit, it must be matched to your rear calipers if not, you will have even more front brake bias. In other words, your rear brakes won't be doing enough braking and when you slam on the brakes, the car will lunge forward.

Then why is there more pad left on the front wheels (85% vs 35% rear). Perhaps the 85% number represents the amount of pad used? Sounds strange.

That's a possible explanation...

even though I was always given brake wear in % pad life remaining...not vice versa...strange indeed.

Front pads are usually a lot thicker than rear pads because of front brake bias, therefore, your rears *may* wear down more quickly. I don't know how it is with BMWs, but on my mother's Accord, the rear pads wear down (percentage-wise) about 1.5x as fast as the fronts do.

I think those numbers are for the amount of pad used. There's no way your rears could wear that much more than the fronts unless you constantly drive around in reverse.
