Z4m brakes

[Simon BB]

I have a very lovely z4mc which is a bit of a garage queen to be fair but is very well maintained and stored etc. Whenever I drive it I tend to get excess brake dust on the near side front wheel relative to the other wheels. The calliper isn't seized and doesnt appear to be binding, I seem to remember reading somewhere that this is common or a feature of how the system works....I.e. application of the brakes as part of the dsc system.

Can anyone shed any light on this......or is it as simple as the calliper needing a refurb?

Thanks in advance of any replies.

The car brakes corners independently to keep you on the road. But, unlesss your only hammering it around right corners, it shouldn't really be noticeable.

Thanks or the quick reply! Yep that's what I thought, so nothing special about the ns front calliper then? I'll whip it off and check all's well.

With standard BMW pads I've not noticed any difference in brake dust NS to OS.

Even then it was about 1000 miles before I'd notice any dust.

same here, i do notice this on the rear wheels however... but that'll be traction control braking the wheels.

Never noticed a difference left to right. Do get more dust on the fronts than the rears, but I would expect that.

My left get slightly more dusty then the right (I have re-furbished my calipers, new pads and discs), however not significantly. Maybe drive the car without braking for a 15-20mins and come the a stop using very light to no brake pressure, pull over and feel the discs. If one is warm, you may have a sticking caliper. Otherwise a caliper refurb is a fairly straight forward job.

Thanks for all your replies and suggestions, looks like the perfect weekend to investigate!
