They are tightened by first a torque then a further angle to stretch them. (Like 70nm + 90degrees) it is what stops them undoing and they are single use. It says under each of these torque settings in the manual “replace after each removal”

Most other large bolts are 200Nm+180° And should be replaced, as should the 90Nm+90° bolts for the rear carrier. It is all in the manual ...RTFM There is nothing wrong with people maintaining their cars, but these cars have modern materials, processes and sometimes need particular tools. The reason they are tight is they are stretch bolts. VW group use them on most of their suspension and brake components. There will be all the usual people that say they have re-used them with no issue etc etc but that is what it says quite clearly in the factory manual. Personally I will occasionally use some of the less critical bolts again, only if I know for certain they were stretched no more than once previously. Bigger ones or anything on my brakes I replace each time.Applications: ball joints on Volkswagen LT, Transporter, Touran and rear caliper bolt on Passat and Audi A3. The welder is a good way of applying heat exactly where you need it. Much better than a wimpy blowtorch.

Rear brake caliper disassembly FL MK2 - Skoda Octavia Mk II
What's it like doing the rear discs on a mk3? On the mk2 it was a bloody nightmare as there was hardly any access to get at the caliper bolts. This is correct. One of the places that does not use stretch bolts is the front caliper carrier. These can be re-used if clean and undamaged. size disc calipers are as follows..& I think the 340mm are the same as the same base caliper casting:-
It's almost easier to cut the heads off the bolts with a Dremel, you'll go through a few blades but you should really be replacing the bolts anyway so it's no loss on bolts and it's easy to do, takes about 10-15mins to cut a head off. It's a bloody nightmare and I needed a special spline drive m14. You dont have any room to get a long enough bar in. Its probably much easier in a garage up on a proper lift. then the ground wouldn't get in the way and you could use a longer bar. An arc will be in the 2000C range, so you only need a couple of seconds to get a bolt red hot. A blowtorch at around 700C will take ages to do the same. All the while heat is escaping to do naughty things elsewhere. All content is viewed and used at your own risk. We do not warrant the accuracy or reliability of any of the information.
