Drilling out front disc torx bolts..

[Eddyg]

so front discs 3; me 1.
The stupid torx head shape just deformed rather than turnig the bolt! Very annoying. One came out easily but need to get the other three out.
In terms of drilling them out whats the best method.
Just start small and keep going and hope is just falls apart?
I don't want drill the thred in the hib for obvious reasons.

Saw some other threads with people having done the same just not sure the best techniques to the the F**KERS out!

Thanks

Ed

Just bolt through the disc and don't worry about them

I had the same problem when i changed my discs. my dad got a very small drill bit and drilled it out very slowly and eventually it just crumbled up. thank god.

got to get the discs off first!

I started small but got bored so went big. I chose a drill bit slightly wider than the torx hole. Think it was 8mm, I assumed what was left of the torx hole would centre the drill. Worked for me. The bolt is counter sunk against the disk so you will only damage the old disk if you are off centre.

I still haven't got round to getting the rest out, they only hold the disk in place while the wheel is off.

had this prob with my BMW, the only dril bits i had to hand were rather blunt and when i was trying to dril the bolts out they were just rubbing and not cutting at all as they were that blunt resulting in the bolts heating up and hardening...tw@t! Then only other option i had was to grind the head off the bolts with my angle grinder, didnt matter about damaging the disc with the grinder as i was replacing the discs, so if you are removing the discs to put new on then this is a option, done in no time with a grinder.. Dont need them bolts anyway..

go big and just drill off the head,remove the disc then remove the rest of the thread from the bolt that is now exposed

 

[Eddyg]

ooo i'm slowing going insane....
need to go find BIG drill bit..

 

[guysy]

Cut a slot in the head and screw it out?

Must be somone you know with an angle grinder? if you havent got one to hand?

 

[sideways danny]

drill it with a 8mm drill-bit. until the head comes off, remove the disk, then unwind what's left with some pliers

Same on my Cup. I used a small flat head screwdriver and hammered the screw anti-clockwise (of course!) moving the angle of the screwdriver with each hit....it soon comes loose.

 

[carrmrc96]

I just uses a drill bit the same size as the srew head and drilled the top off, when the disk is off get some mole gripls and screw the little stub out the hub.

 

[Eddyg]

Bigger drill bit did it. Although battery on drill ran out! 1 More to go! little buggers!!!!

Ive got the same problem but with a little extra added. One of my wheel bolts has sheered off AND the torx bolt has rounded off. What I need to know is, do the wheel bolts go through to the hub? Or are they just to the disc?

If I get the disc torx bolts out will the disc come off or will it still be stuck on because of the sheered bolt thread that is still in the disc?

Dont wanna waste my time drilling out the torx bolt if its just not gunna come off. I will just take it to a specialist if its through to the hub.

 

[sideways danny]

the disk is not threaded, only the hub. Pretty simple to remove a broken wheel bolt once the disk is off. you should be able to grip the end of the thread behind the hub

 

[Moz168]

Ok thanks, gunna have a go tomorrow. Your fault Danny if I f**k it up

 

[Twisty]

Drilling out bolts drove me insane until I got a carbide drill which slices through the bolts as if they are made of cheese.

[Eddyg]

Ugh stress... Got driverws side all done and new disc on drilled out the retaining bolts easy with a bigger bit..
Just got the problem of on the passenger side where i snapped off the torx bit in the hole, advice never snap tool!
Are carbide bits the hardest you can get?

 

[jay s]

once you get them out dont bother putting new ones in, real s**t design and always end up f**king up

 

[Moz168]

Stress also. Have you go yours off yet Eddyg?

This is where im at:-

Should it just slide off now? Or does the hub nut also need to be off? Or do I need to drill the torx bolt right the way through? Ahhh help!

 

[iimushroomzii]

The disk should just come off now mate!

 

[Moz168]

The disk should just come off now mate!

Well it aint coming off. Ive been at it with a hammer too. To me it looks like the disc is held on by the hub nut. How else it it being held on?
I will get at it with a hammer again tomorrow, its extremely frustrating. Everything its ive done on this car has gone wrong

 

[Eddyg]

I know how you felt mate!. Yea looks like it it should. If you are drilling them 10mm bit does it. Don't snap a tool off in it. The middle nut doesn not need to come off. It slides over the case around that nut. The disc may just be stuck on a bit. Give it a good slam..just trying to bleed the system now after the new lines...taking a while!

 

[steviet]

Hit it harder , with a bigger hammer till it comes off. Itll be corroded on to the hub, so tapping or gradual pressure wont shift it. Brute force and ignorance FTW!!

 

[Twisty]

I suggest bashing the back with a rubber mallet while rotating it round a bit at a time. Or grab both sides and pull back hard shaking it from side to side (making sure you dont pull the car on top of you).

I had exactly the same thing as you, snapped wheel bolt, and it happened again a month later. I figured they must have been fatigued by overtightening at some point so I replaced them all.

 

[chrispy.clio]

When i was changing my discs i started of hitting the disc with my hand, then a small mallet, metal hammer, bigger hammer, much bigger hammer. Eventually i won and the disc came off.

 

[Twisty]

Did you get it done?
I just changed my front disks and it took nearly 5 hours. I hate rust!
I kept the torx bolts but I used copperslip on them rather than threadlock.

 

[Moz168]

Yeh I did, the disc came off with a few wacks of the mallet. But got pissed off and fucked the hub lol. Couldnt grip the bolt from the back so drilled a hole and tried to wedge something in there to undo it but it would budge. In the end I just got really annoyed and kept drilling with bigger bits, hoping that a little bit would come away so I could pick it out but it didnt and now theres no chance of gettin it out.
Emailed Josh @ Cliospares for a used hub.

 

[Twisty]

Sorry to hear that.
When my first wheel bolt snapped I didnt try to remove the disk. I just kept drilling larger holes until the the bolt was gone and chased out the threads. So that is still possible.

 

[Moz168]

Well the drill didnt go through the centre, was slightly off and I think its drilled the thread on one side. Just trying to source a new hub atm now.

 

[Mike...]

Bit of a bump here.


So I'm on with this job at the minute and have got a bit stuck.

I've drilled I assume as far as the threads in the bolt and now the drill just wont budge at all, seems to be doing nothing.

When can I start knocking the disc with a hammer? How long do we think I've got to go?

Attached a pic,

Any tips would be great cheers.

 

[Budgie]

You've got about the same to go again before it'll come off.

Small sharp drill to do a pilot. Then up the size everytimw

 

[ilovewilly]

You could hit the disc with a hammer without even attempting to remove/drill and it would just shear the head of the torx screw off - but I wouldn't recommend brute force where it isn't strictly neccesary.

I can't see your image on this PC but once the head is drilled off you can remove the disc and then continue to try and rescue the hole with greater visibility.

 

[George@RTR_Parts]

Can't do it now, but for future reference impact drivers are great for these mate

Or you could/can improvise with a punch and hammer, same result hitting and turning it at same time to shock it.

I managed to get mine off with a chisel.
As a note, initially I was using a wood chisel for quite some time, two hits with a cold chisel and it budged it no problems.

 

[aucky]

I drilled the centre out then hammered a cross head bit in to allow me to unscrew it

 

[Mike...]

Going to attack it with the drill again tomorrow, got a feeling its not gonna go well though.

 

[chris blue]

whats size Torx head is it? 40?
(Realise this is a thread resurrection)

Yeah its a 40 .

Get at it with an angle grinder and cut around the heads. New discs
