Brake disc screw

[braincat]

I knew it, changed one sides discs fine, got to the last one and that damn stupid irritating locater screw has rounded itself off. Has anyone got any magic tips or is it a case of drilling it out?

[jbee]

i had to drill them out and retap mine on both sides
took me 3 hrs with the crap drill bits i had

You got a dremel or something to cut a line through it to get a screwdriver in ??

[braincat]

Thats a cracking idea, don't have a dremmel but I think I'll go get one...
Nice work fella.

[maxfield]

or you could weld a screw on top of that to get it out ???

just another idea

[fuzzy]

drilling it out and using a stud extractor doesnt take long(15 minutes?).use a decent drill bit on slow speed.wont need to re tap the threads.a pack of stud extractor bits is very useful to have and are cheap to buy.

Or if you dont have any of this fancy stuff put 2 opposite wheel bolts back in a few threads, remove caliper and carrier if you havent already and smack the old disc from behind with a large hammer.
Once the end of the screw brakes off the wheel bolts will stop the disc from flying and the remains of the screw should come out with mole grips.


Should take less than 5 mins if you can swing a hammer

Use an impact driver, set for anticlockwise, cheap to buy if you have't got one and comes in very handy for these types of jobs........

smach a flat head screw driver into it and undo it like a screw

yep, this is probably he best method, providing you're changing the discs aswell...

tip for next time, put that screw in with loadsa wd40, and once its in, cover it in brake pad grease, to stop it going rotten...

An appropriately sized Torx bit is even better (ask me how I know )

I had one that an impact driver rounded the head off it was stuck that tight, tried boiling water/heating it/wd40 etc
It refused to drill out, and became so rounded I couldnt hammer anything into it (you seem to hit a harder layer of metal partway into the screw?)
The only solution in the end was to smash the disc off with a big hammer, then hammer a hex socket over the remains of the screw and use the impact driver on that

Make sure you put plenty of copper grease on the replacement screw!

Or even just smear the thread with copper grease, much better option, I use this method every time I work on the car, including the wheel bolts, and it makes life so much easier. I picked this up from BMW themselves after noticing it after having the car serviced by them.

Copper grease solves all your fastener problems. Silicon grease solves all your electrical problems.
Every E30 owner should have a pot of each!
Smack the disc off with a lump hammer as described above. Remains of the screw can usually be removed with just a pair of pliers.
