Grand Voyager 2005 2.8 CRD 150,000 miles

About 18 months ago I changed my brake pads front/rear to EBC greenstuff, with new EBC front discs (rotors?) and kept the original rear discs.
The brakes were a marked improvement over the standard, much improved...untill a couple of months ago. Over a period of a few weeks my Voyager developed a judder, felt through the steering wheel when the brakes were applied. Nothing felt through the brake pedal. Problem got progressively worse.

EBC technical recommended skimming the discs, which is what I was about to do. The discs were a bit discoloured, not a uniform colour across the whole disk, (not heat), pad wear was even.

I found this website.

I realised I had been doing much more town driving than usual. All I started to do was put it into park when stationary, ie not sitting at the traffic lights in drive and holding it on the footbrake. Within a week the judder was much reduced and gone completely within two weeks.
I suppose town driving can get the discs quite hot, lots of touching the braking and not much airflow to cool them down, and then I was clamping the pads firmly to the disc for something like 30 seconds at a time.

I suppose this could all be coincidence, I just posted it in case it helps anybody out.
