Title: Brake disc help !!!!!
Post by: Wisey on 21 March 2010, 19:29

Am trying to take off the front passenger side brake disc. But who ever put the disc on last time rounded the head on the screw that hold the disc on  :angry: so i drilled the head of the screw.

But the disc just doesn't want to come off  :undecided: tried giving it a bash but still aint playing  :grin:. The caliper is off, so is it just that wee screw that holds the disc on or am i missing something? Or do i just need a bigger hammer and hit it harder ?  :grin:

Hi
You will need to drill more than that. OR
Soak it with plus-gas. Drill a small hole to hammer in a flat screw driver then unscrew the rest of the screw.

Depends how the screw goes in, you could of drilled behind it, tapped the hole and used a bolt/screw of approriat tap to extract it out in a clockwise fashion, thats providing you can get behind the screw.

Otherwise buy a screw removal kit, or screw/bolt extractor which can be picked up quite cheap.

Halfords do a the Laser sets, screwfix also stock a kit:

Have a look around, they are called "extractors" or screw/bolt extractor kits, just look out what size you need, as I know on the polos it was a M4 CS screw, not sure what it is on the golfs.

The head is already been taken off   :rolleyes:

And i have drilled enough cos you can see the there is enough off the screw so the disc should just come off  :huh:

Should the disc come off easy or could it be stuck on if its been on there for a while ?

Should come off easy, not a rust issue? If so try heating it up with a blow torch and letting it cool off, the expansion should loosen the rust, just watch out and don't burn the brake cable etc... Otherewise

You know it makes sense  :grin:

Hi you just need to spray the center bit of the disc with some wd40, give it some time to work in then wack it off with a hammer, it will eventually come off!!!  :smiley:
