Problems carrying out wheel stud conversion!

I've got some 20mm spacers for my new wheels as the offset is et38. I'm converting to wheel studs at the same time and I've just attempted to fit the first wheel and started on the n/s rear.
I screwed all the studs in tight and used threadlock. Everything went ok until i dropped the car down to find that the handbrake is completely stuck! I carefully tried to ease the car forward coming off the clutch but that corner was just squatting, not budging.
I'm guessing the studs have gone too far and jammed the handbrake mechanism. Any ideas?!
The car in question is 325i so has rear discs.
Cheers in advance,
Max

did you use longer wheelbolts ?
and when you say you threadlocked them, do you mean the wheelbolts ?

are they spacers that bolt to the hub, then the studs screw into the spacer?
or are they normal spacers, which fit over the studs and are clamped by the wheel?
i'm guessing theyre the latter, and the back part of the stud that screws into the hub is just too long. i'm affraid the only way to tell is to crack the threadlock and remove them.
could you undo the disk retaining screws, and slip that off so you can have a look inside the drum mech?
if it is as simple as the studs being too long it shouldnt be tricky to cut off the excess

I'm using studs and nuts instead of bolts. I threadlocked them just to help them hold, i used medium strength stuff so they can be removed if need be, thank goodness i did!
The spacers are normal, hubcentric obviously, clamped on by the wheel.
Yes hopefully if i get the disc off i might be able to see whats occuring.
Thing is though, surely if the studs are too long, trimming them down won't help, because i'll still need to screw them in until they hit something anyway, so that they go tight? If I screw them in just enough so that they're in the hub then but not up against anything, then i'll justs be relying on the threadlock holding them in, is that enough?
Thanks for your comments so far guys.

Hi
I had the same trouble, the studs have a unthreaded section were they tighten up, one stud went further in as the hub basicly acted as a die so i srewed it out to clear and reaplied thread lock.

I'd suggest removing conversion studs and the rear discs
THEN
Inserting the conversion studs again( with threadlock) untill there fully threaded through the hub, but protruding by no more than 1mm or so
Spin the hub to make sure they aren't catching on the handbrake shoes or mech then refit the disks, adjust the handbrake and refit the calipers.

I use studs and have them lock wired at the back of the hub, maybe 6/7mm sticking out and have no probs at all.
