Hi all.

Managed to snap a bolt in the hole where the Allen headed screw holds the brake disc to the hub.

I mistakenly took it for a jacking bolt hole to push the disc off. I drilled it and then used a stud extractor which promptly snapped in the stuck bolt and cannot be removed. So no there is no.chance to remove the broken bolt.

Before I remove the hub and replace , does any one know if once removed , will I be able to get at the other end of the broken bolt to try and turn if from there, or is the hole inacessable and should I order a new hub and save myself some time?

I've looked on google images and am undecided to wherever on not it will be accessible .

An engineering shop may be able to help you if you get the hub off. One day your life will flash before your eyes......................................make sure yours is worth watching!

If you mean the guide pins (number 4 in the image below) then they do go right through but they will be a barsteward to get out from the back. There is a square collar on the face side that tightens up to the caliper carrier and would take a bit of shifting without the proper tools. An engineering shop should manage without too much problem or scrapyard for some used parts

Why not grind the disc around the bolt until you can remove the disc and then remove the remains of the bolt with Molegrips or similar.
If you can't get the remains of the bolt out of the hub just cut it of flush, it's not necessary anyway.
Discs are cheap to replace.

Do you mean the grub screw that holds the disc onto the hub?

Just the one, yes?

Having broken it can you get the disc off and on?

If so, the grub screw is not necessary for safe operation, the pads will hold the disc in place until you get the wheel on, and the wheel nuts will hold everything in place.

If the disc won't come off, just grind/drill etc until you can.

Both my front wheels had these grub screws missing when I first got the car .

^^^ That will be number 9 then....no not that number nine


A good sharp cold chisel will remove it

A good engineering shop with a spark eroder will get it out without damaging the threads

Hi gents,

Yes its number 9 in the drawings, the one that holds the disk to the hub. As it was snapped the disk came off, but unfortuatley the bolt I threadded into the hole for number 9 , snapped and cannot be removed now. I refitted everything back together , hoping that bolt 9 was not needed, but its making a fair old racket , rattling away. It sounds like the disk is moving , but it could be the longer bolt that broke scraping on the inside of the hole.

If I can find somewhere with a spark eroder, they might get it out, but I'm still not eure I have not damaged any other part of the hub, by screwing a longer bolt into hole 9 in the first place . Thanks gothe good pictures guys, where do you get them from ? MY2010 TDV8 Vogue Ipanema Sand

Hi Woodie, if you grind the 9 bolt flush with the hub, you should be fine as I agree with the above, you don't need it. It only helps keeping the disc in place while you mount the wheel.

Another option to remove it is, grinding it flush or at least flat. Take a small diameter drill (say 1 or 2 mm) and drill the center out. Use a centerpunch to help stable drill start. Then make the hole bigger and bigger by going up 0.5 mm till you are close to the threads. Buy a left threaded conical tap (don't know the proper English term) and screw that into the hole to remove the remainder of the bolt. Once it is out, use the correct thread tap to clean the threaded hole and you should be fine. Use cutting oil generously while drilling and put little pressure on the drill (make sure the drills are very sharp) so they won't snap. Sharp drills cut very well without a lot of pressure on them.

The other option is spark eroder or welding something to the bolt (if it is still sticking out enough) but make sure you disconnect all the ground and positive connections and make sure the earth of the welder/eroder is actually on the hub and makes good connection. Otherwise the current can fry your electrics/electronics !! MY 2010 5.0 SC Galway green and sand interior!!

The disc can't be loose, the wheels hold it in place tightly, unless your wheel nuts are slack.

If the disc is solid enough, then as long as its not my dust shield, which it shouldn't be as I just fixed it with penny washers, it must me Tue long bolt I've broken off catching inside of the hub somewhere. What is really like to know is if I can access the back of bolt 9 when the hub is removed, other wise its going to be a new hub. MY2010 TDV8 Vogue Ipanema Sand
