Your (so called) mechanic probably re-used your old calliper bolts instead of new ones. He may have over torqued them too. These bolts are under a huge amount of torque and when removed become weaker and so should be replaced. You could sue the garage for this serious safety issue. You should get them to do it properly this time and ask for all your money back. You know it makes sense..

Most likley left them undone, (takes a lot to push a bolt past its elastic limit.) are your wheel nut tight as well

You can re-use any of the bolts fitted, neither are stretch type. The caliper bolts need to be coated with thread lock if re-used, the allen key type bolts that hold the carrier can be re-used also.
I think from the picture the allen key bolt has come out, as it appears the whole assembly has pivoted up.
The problem may be it hasn't been tightened to a high enough torque.

+1 I always use loctite on caliper bolts.

I'm sure i read somewhere that vw used thread lock on the allen key bolts on mk3's. Thats why they are so damn difficult to get out.

I am sure they do plus I believe new bolts come coated with loctite as well.

Its the slide pin bolts that have loctite on them and these bolts must NEVER be re used. The allen bolts are the calliper mounting bolts and do not need loctite. It is worth replacing these as the heads are sometimes damaged when undoing and could round off. For the sake of a couple of quid why wouldnt you replace these anyway? We are talking about safety after all?

The slide pin bolts don't need to be replaced at all. They just need a fresh coating of loctite.
If you get new ones with new pads/discs, use them, if not just re-coat the old bolts.
