Bolting disks to cortina hubs...
Do I need to use the 2 washer things with the bend up tabs or would some threadlock do?
Do Ford/motorfactors stock them if I do?

i used "frilly" washers, well thats what the local nut tart called them anyway,
think its spelt Snoor and pronounced "snore",
much lighter, thread locker won't hurt either.

I thought i read somewhere on here (very recently) that they failed sva because they didn't have the tabs on......

I used thread lock, a torque wrench and reused the old tabs. Although I reused the tabs I used the side which hadn't been bent before.
Cheers,
Craig.

I've managed to kill the washers on 1 side when i torqued up the bolts. I think I'll just use frilly shake proof ones or heavy duty spring
washers instead. That is if a local motorfactors doesn't have any proper replacements.
BTW, what's the torque rating for those bolts? Our cortina manual seems to have gone walkies...

Mackie,
I got the torque figures from someone on the forum so try a search. I think it was something like 30 or 32 lbf.ft for the four brake disc bolts and
then the hub was something like 27lbf.ft and then backedoff 90 degrees or something.
Let me know if you can't find the posting and I'll have a look for you.
Cheers,
Craig.
Here is the thread I was talking about.

is it really an sva requirement to have locking tabs? i knackered mine when i had to angle grind a rounded nut off when replacing my rusty discs.
guess if it is required to lock these nuts, then mr sva can't really check for threadlock...
if you don't fail, you aren't trying hard enough.

I wouldn't rely on threadlock alone due to the fact that it may be affected by heat in the brake discs. I would strongly recommend a mechanical
locking method as well. I must admit, I personally don't like those "frilly" washers and prefer the heavier coiled spring type
washer for applications such as this.
Can't you just get locking tabs from somewhere or in fact make some from 16swg steel? One less thing to worry about...
Cheers,
Craig.

Tried buying locking plates, could'nt get them anywhere, so made them myself using the attached pattern; print it off, stick to the sheet steel
(I used 1.2mm/ 18swg Zintec), cut and file to shape.

good for you that you have the inclination to do a proper job, but this fiddly stuff that doesn't add value or affect the car just annoys me,
don't feel like i've done anything. might just use a small straight piece of steel with a hole towards one end maybe 3/4 along it - the
long bit on one side of the hole will provide the locking, the short bit on the other side gets bent up as the tab. just make 4 of those for each
side. hopefuly not more than 10 minutes all done.
if you don't fail, you aren't trying hard enough.

What is lockwire and how does it work?

Skinny,
It wouldn't take 10 minutes to make 4 proper locking tabs from the design given above, especially from 18swg steel which you can easily cut with
tin snips or ideally a monodex nibbler.
Also, bear in mind that it is the fact the tags are paired up that stops them spinning. If you make then as single locking tags then they won't
be as effective.
I agree that sometimes the detail tasks can be a pain but these are the things that will impress an SVA inspector when the time comes, especially on
safety critical systems like brakes. Speaking personally, these are also the areas that I am most proud of from my own build.
Cheers,
Craig.
