I wanted to share this with you as I can't find the last post I was reading on this subject (was a couple of years back).

I've suffered brake judder since I had the car. So, four years or so. All the usual suspects have been serviced, replaced, checked, lubed. Still had brake judder.

It miraculous went away the first drive after getting an EGR bypass. I can only assume the vac pressure system used for the EGR is somehow linked to the brake vaccuum somewhere. I've waited some time before posting this as I know it sounds rediculous and didn't want to get flamed. But if those systems are linked then it's feasible. For sure, this problem has not come back since the bypass.

So anyway, if you've tried everything and still have judder. Try the EGR bypass (or just remove and block the ECP for a while and see if that helps).

I re-itereate, I've had this problem for several years and it went away immediately after bypassing EGR.

Hope this helps someone else!
