I have a banjo diff that's been converted to disc brakes that I got cheap.
Its complete from disc to disc, but needs a rebuild.
I don't know how it was converted as I can't see any welds etc.

Just wondering about past experiences any of you guys have had with a similar diff.
Is it worth using?

Will get some pics up after the weekend if wanted.

Cheers.

its basically a straight bolt on job to convert to disc

[Collo]

Cheers guys. I didn't know discs were an option on the LX.

I just assumed it had been converted.
I don't if its torana stud pattern either.

Just went and had a look, had to move some shit...damn shed...

Measurements are 15mm thick rotor and roughly 10 inches diameter.

Dodgy phone pics...



Has a 2 near the centre.

Can you tell me whether this diff ssembly is torana stud pattern or L34/A9x/Hq stud pattern?
and If you remember where did you get it?
I had my L34 diff convertedmy banjo when I had my car a long time ago and I was wondering if this could be my old diff
cheers

I thought that the LX that had the discbrakes from the factory had the baby salisbury diff fitted.I could be and probably am wrong on that count
Someone will know
cheers

The a9x and uc had the salisbury diff.

Standard LX had the banjo as far as I know.

I don't know what pattern it is i'll check when I get back home after the weekend.

I got it from a wreckers in newcastle who said he found it at a house he was getting a car from.

Hi Guys.

The only LX to have rear disc brakes was the A9X.

The first 'normal' Torana to have rear disc brakes as an option was the UC & these were fitted to the 'baby' 10-bolt Holden diff. The axles & caliper brackets etc. will all fit straight onto an LH/LX Banjo housing. As far as I can see that is what you have in those pictures.

i always thought holden calipers were in the rear side of the diff housing not in front. Cheers

The UC had both versions. The early ones were front mounted & the late UCs were rear mounted (or could have been the other way around).

Thanks guys.

I had a rear disc brake conversion done many many years ago on the original banjo diff. It basicallly comprised blank rotors drilled to Torana pcd and a redrilled XF Falcon rear disc aluminium braket and calipers. Minor welding on the handbrake braket allowed the hand brake to be retained.

[Collo]

So it shouldn't be an issue to get it reconditioned.

And just out of curiosity, what are the calipers on it?

PBR UC Torana

Cheers mate.

I'll have to check the stud pattern tomorrow.

Also, would it need an eng. cert. if I decide to use it?



Cheers.

As far as i'm concerned, "No" is the answer.
Its a standard diff with standard factory parts bolted on, no mod!
Just went through the diff rebuild and swap myself, one of the best upgrades i've done to the Hatch.
Here's my thread on the build and swap, http://www.gmh-toran.......st&p=285128
Only downfall is the replacement disc's are no longer available, so you need to find good secondhand spares, getting tougher.
Their has been mention of new ones but nothings happened yet

Thanks for that mate, good read.

And the heads up about the handbrake cable.

Can you use new HZ/WB examples? By redrilling the disc to Torana pattern and machining the OD down to suit?

The other method could be to get your axles changed to HQ stud pattern (run HQ front discs) and run 14" wheels. Then you could use HZ/WB rear disc setup (discs and caliper carrier). I think you'd be able to use the UC caliper and handbrake mechanism (from a 20 year old memory of these).

[Collo]

Thanks for the info guys, I just checked and it is Torana stud pattern.
I'd prefer to keep the early stud pattern if I can.
Can you get blank discs and get them drilled to suit?

[Collo]

The discs should be available for sale later this year. Initially, 8 will be available for sale.

Any idea on a price?

[Collo]

Cheers mate.
I wont be using that diff to start with, I don't need it for a near stock 253 and it's one less thing I have to pay for, for now...

Interested in discs for it though.
