Hi thanks again for your replies. I was hoping that a new thicker disc would stand the excess heat better than a thin worn one, having had to drive half a mile or so from where the recovery dumped us to the only garage in the area that would look at the van,the 4 hour wait for the recovery had allowed the hub to cool completely, there was no judder or vibration on braking and the mechanic who initially stripped the calliper did look at the disc so it should be ok.
My mechanicing skills went into decline when I bought my first Nissan Bluebird, had 3 in fifteen years, dull as ditchwater but utterly bulletproof. Also found a mate was an ace mechanic and has been servicing my car/ bike since 1996. The T 6 is the only vehicle I bought new and stayed with the dealer for the warranty but that last service was the last time. I have replaced brake pads in the past but not a calliper. I don’t have a big enough hex socket to undo the calliper and the mechanic assures me that when the parts arrive he will fit them so I’m not going to risk making an arse of it. Thanks for the offer of info re tools etc.
Getting the parts has been the major issue . Broke down last tues. by wed pm garage stated the parts were not available at any supplier??? I remembered a fellow windsurfer who lives in Germany and works for Audi who with my VIN checked vw systems direct and confirmed plenty of availability 24 hours to any vw garage in Italy. Problem may have been that in 2018 vw changed the part no for the calliper by adding a X (denotes exchange part) but in late 2022 changed it back again. Any search including the X would return “now unavailable “. This was passed to the garage and by thurs lunchtime and the payment of 300 euro deposit told the parts would arrive wed , fri next (now this) week . Again ordered with our VIN so should be correct but I will believe it when I see them.
However on a campsite near Oulx been stuck in worse places.
Thanks again.
