Halfrauds also sell a twisted one for about £8, i did from the kink in the top rail backwards all 4 sides of every tube and it is just a bit small now to use again, and not being a "cup" it is easier to get into the tight corners with and also doesnt kick back so easily. will need another one to finish the front of the chassis off.

Oh, don't get me wrong- you need one (or a couple) of each!
The cup ones and the saucer ones!

Halfrauds sell the twisted saucer one (mine's lasted quite well) for £10 round here.

I found it was the saucer ones that jumper the most and as I've said elsewhere it was this one that jumped the grinder out of my hands!

The screwfix order just arrived so we now have 2 the tools. Tonight i think i shall make stuff shiney!
I also ordered some smaller, finer drill brushes for doing the fiddly bits and get a smoother finish.

Mackie,

Do it outside (away from cars, windows etc.) as it'll cover everything in crap if you do it in your garage.
Bear in mind you drive will rust if you leave metal all over it.

Unfortunately yes.

The worst thing is my father pressure washed the drive in the spring so all the grindings that I never bothered to sweep up have rusted and given most of the nice clean drive a nice brown look.

Another thing to watch out for is the 'metal powder' that seems to come off when grinding. This settles on everything (newly pained white window sills, frames and garage door being favourite) and then rusts aswell.

Really goes down well that does!

also never cut/grind with an angle grinder so the sparks hit glass as the hot sparks melt into the surface and then rust.

I'm the voice of experience in that too:

body count so far is:

1x bathroom suite (toilet, cystern, sink, sink pedestal etc.)
2x mug
1x double glazed window
1x rear view mirror

you'd have thought I'd have learnt by now!

Gave me something to do whilst sitting on the bog!

Nah, Joel is right- my Dad was keeping an unused (ready to be put in when the new toilet is built) set with these bits in the garage- as y' do!
But hey, I wanted more space in the garage anyway so chucking was a Godsend!

Think I found someone who has the rocking-horse-poo-rare Cortina "split the caliper" O-rings - for 80p

Me:
quote:

Also, can you supply parts for Cortina front calipers (type 16 I think)?
I know that normal piston seals are available but I would like to find a
source for the bolts and O-ring that I understand I need if I want to
split the caliper.
(I'd like to split it so I can better clean and paint it)



Brakes International (sales@brakesint.co.uk)
quote:

The M16 caliper repair kits are available but do not contain the 'o' ring
that you require but we do have some of those at a massive 80p each and you
will need 1 per caliper.The bolts we do not have as they are a special
tensile bolt which the tensile strength is marked on the top of the bolt
that is already in the caliper.We can also supply re-con calipers at ?31.56
each exchange to save you getting your hands dirty

Delivery if reqd ?6.00 next day with ups excluding saturdays at ?27.00

All the above prices quoted are subject to VAT.

Any more information please ring me on 01254 695695

Brakes int. do recon kits for £3.80 + vat each side, and they do the split-caliper O-rings which I don't see on darren's site..

am I missing something?

I ordered 2x cortina front caliper recon kits, 2x sierra 4x4 rear caliper recon kits, new discs for all, new bleed nipples for all, and the cortina split-caliper O-rings. £6 delivery made it £81.

Very friendly and helpful service, I can reccomend them. Cheers James for alerting me to their existence.

By the way, on the subject of splitting cortina calipers, I went to ford parts department to try and find some replacement bolts for this operation, and apparently they have never sold them.

Given that and the appearance of the bolts (no waisted section, don't look like fancy stretch bolts), I think the originals are reusable.

And the o-rings look perfect in ours too... But you can get them from brakeparts.co.uk.

bolts and splitting calipers

Blueshift;

Ford have never stocked the bolt because Girling wouldn't supply it as a spare part. They argued that if they didn't supply the bolt then no-one could split the caliper (as new bolts were recommended).

The bolt is designed to stretch at a pre-determined torque level. The strain energy stored in the bolt (by the stretching) then stops the bolt from loosening due to the vibration from the road wheel.

Used bolts will be stretched and should not be used - brakes are safety critical after all. Is it really worth the risk? Girling didn't think so.

surely a simple bit of drilling and lockwiring would solve this problem?

Can't be done on a 'mass production' basis. Calipers are built in <1 minute total cycle time at our factory.

Doesn't guarantee adequate clamp load on the seal. You will only realise that you didn't do it up properly when you put your foot on the pedal.

Lock wire will fatigue due to the same vibration. Then the bolt will come undone! Aircraft use lock wire but all bolts and fastenings are checked regularly. These bolts are NEVER checked for tightness after the caliper leaves the manufacturer.

But you can try it if you want

so begs the question when i put my m16 calipers back together with my new bolts that came with the spacer kit what torque should they be done upto to ensure the bolts are correctly stretched!

Ned.

Bolt torque

Hi Ned,

If you have the same spec' bolts as were originally fitted by Girling then they should be tightened to 75/95 Nm (that's 70/55 lbf.ft).

I stress (no pun intended) that this is only applicable IF you have the same spec bolts as were fitted originally.

Crapsticks. JAG, do you know the specs for the bolts? We have them out so can take dimensions off them, but can't tell what tensile rating they would be or if they're some fancy alloy.

I wonder if ned's people would supply just the bolts..
