potentially...ouch!
had the same on ours - judder on braking,
we had foolishly not been out in the car for a long while - and the discs had been affected - think this si a known thing not to do with 993s - at least I now know it is thing not to do
]
so new pads and discs all round - at least it now stops very very promptly, and am motivated to drive much more regularly.
Think some people have said you can get brake dics skimmed? is this feasible
Might this be a solution?[8|]
How calculated a risk is buying supposedly excellent condition discs off e Bay??
Though faffing of getting discs off, and to a machine shop, then re-fitted - is going to start getting close to just getting Indie to fit new pads / discs.
1 last thing - our aftermarket disc seem to show surface rust on the hub much, much more than OE ones, ( we can see this clearly as fronts were OE, and I managed to check witht he garage before he'd fitted OE to the reears so saved soem funds for something else.[]
so if you are going to use aftermarket dics - suggest you paint the hubs before fitting ( sure someone here can suggest a good variety of paint type to use ( hammerite / engine painnt etc. etc.?.

As the gent says this is a known problem with the 993. Thats why a lot of weekend drivers dont take their cars out in the rain, not because it gets wet and gets dirty but for the fact if you garage it wet and it may be a while before you take it out next, you can end out with this issue. Mine is a weekend car and because my use is so speradic even if I wash the car, I take it out for a good drive to fully dry everything off before I put her back to bed!
I fell for this when I 1st bought the car 7 years ago, now with parking it up dry, touch wood never had the problem since!

I was plagued by this some years ago. In my case I discovered the front caliper plates were lifting due to corrosion behind them causing the pads to stick/not move correctly. Managed to clean them and reinstall with copperslip grease and never had any problem since.

Is it worth getting them skimmed? I find I need new (Porsche) discs every second set of pads through wear as they're so soft. It's something to do with not as much chrome being used in the metal of the discs apparantly. Skimming them just takes them much closer to their minimum thickness.

It worked for me, as the MOT picked up corrosion on the inner face of the discs. It took a few miles for the old pads to bed in again but now they are better than before.
The skimming is a misleading term, its more like surface grinding and the discs stay on the car while its done.
I suspect that you are covering more miles than me, but a new pair of front discs for every two sets of pads would seem about right based on my everyday Audi wear rate, and is probably a better option for you.
I had the same issue on my previous C4. Discs and pads were changed as they needed doing, but the wobble returned after only a couple of hundred miles. The discs were skimmed but the wobble returned, albeit only very slightly. It was suggested by the indie that the hub could be out of true, but I sold the car before taking it any further.
"so if you are going to use aftermarket dics - suggest you paint the hubs before fitting" .....it's the part of the disc that bolts to the hub that needs painting on cheaper discs, not the hub itself.
