Had that prob for a while with last pad / rotor change. Gone now thank god as it made threshold braking very awkward.
Really? I know we both go to Knacky for tyres.

Still a little gap, but seems to be getting better each time I drive. It doesn't seem to be noticeable now.

Had a good drive today, and the slack is still evident. How did you solve the problem? When I release the brakes after it starts bitting, they work awesome. However, after I drive for a little bit, the slack is there again.

Anyone else have any idea that would be good.

I think it is slack as how koastal described. If I lightly touch the brakes there is a click but no stopping but a little more than there is feedback and behave normally. Once engaged and released completely and apply immediately there is no problem.

If I engage the brakes quickly enough then it doesn't seem to have any problem either.

It was bedded according to instructions.

Bleed the fluid again, doesn't sound like it was done properly. Needs to be done by BMW dealer.

I might try to bed it again and see how it goes. Might just need some hard driving for the callipers to adjust. Failing that, may be trying to bleed it again.

It doesn't feel spongie - the brakes pedal needs to travel further before it bites, so it shouldn't be air in they system.

When mine had this issue it was immediately after I changed pads rotors and front brake lines.
It felt like the pads were retracting further than they needed to. This issue disappeared after a track day. Perhaps a late nite spirited fang to Noosa through the roundabouts will help. Always makes me feel better

Thanks, definitely, will try to bed it again, and then put some heat into the brakes after.

Took it to a mechanic closer to work today recommended by my tyre guys (highly recommended! - PM for details). They bleed the system with their ATE pressure bleeder and got all the air out on the first go. Also found that the rear pins and spring on the callipers wasn't inserted properly causing the loud click when braking. He also adjusted the handbrakes as well.

Now, with it fixed - the brakes are just sensational. I have so much control over the brakes now. Now, just need to see how good they are on track.

I had the CDV removed as well, and I have no idea how much better it has become. I always thought I was a crappy driver with the poor gear change, but it is just CDV doing its nasties. Always thought CDV is there to design to save the clutch but I have to conclude that it is only there to protect it if you dump the clutch. Otherwise, what it does is just create unnecessary slips.

Now, I am happy .

Great to hear Steve. I bought one of those pressure bleeders a few years ago. Good investment if you like to DIY.
CDV is there to save the whole driveline not just the clutch but it makes the clutch take up point sooo much more predictable. Have you got a clutch stop yet too? Very easy to fit and nearly as good a change as the CDV removal.

Not yet with a clutch stop. Will definitely looked into it.

Finally, got the car onto the track finally yesterday and gave the brakes a good workout. They were absolutely sensational! Ran a 28 laps run second stint at QR and it didn't fade at all. Unfortunately after 68 laps the car was out of fuel. Highest temp I saw at around 30 ambient was 135 even after the long runs. The PSS was great I thought, and hold up very well, and looks like it works with a great range of temp - not much difference at lap 28 and lap 1.

The tiny little uptake which inconsistently happens on the brakes are gone after the track day. The pads probably just need some speed for it to get set.

You never mentioned the fun factor rating Steve, I assume we're talking 11/10?

Pics?

Thoroughly enjoy myself - not a day for pics - not sure if Biz took any. Got logs for all my laps though.
