Rear disk pictures?
Has anyone got any pictures of a rear disk setup on an Avon? Do the calipers end up on the front or the back of the uprights?
I've tried searching, but can't find anything. I think pictures have been posted before.
Cheers

Hi Graham,
Look at Lightning's photo archive (rear end chassis and diff).
I think that'll answer your question.
Sorry, dunno how to post his picture onto here.
By the way, did you manage to turn down the ABS teeth on the hubs ok?
Cheers,
Andy.

Cheers Andy,
Forgot Lightning had them fitted on his!
I've not done it yet as I want to mount the bearing carriers first so I can see how much to take off. Are you fitting rear disks?
Cheers

At present have push-in driveshafts and 8'' drums fitted.
But, a few months ago, I bought a complete 3.62 LSD rear end inc. hubs, lobro driveshafts (with ABS teeth!) and calipers for the bargain price of £50!
(well worth trawling through your local freeads paper!)
I,ve bought new discs and am awaiting delivery of reconn'd calipers. Diff and shafts need cleaning and painting. (I was thinking of using the
electrolysis method - how did you get on with it?)
I dunno whether to swap the rear end now (no bodywork fitted yet) or wait till after she's on the road and fit it as part of a future upgrade
where I'll also be changing from pinto to fireblade power!
So, if you get your finger out and fit your rear end, you'll be able to tell me how much hassle it was (or not!) and I can make a decision
accordingly!
Cheers,
Andy.

I can already tell you, FIT IT NOW!!!! 
It's a twat of a job. Just imagine removing a diff full of oil with the bodywork on and fuel tank in. It's like something off bloody
Crypton factor anyway!

I have a far better idea - as my build is the 'least complete' you should deffinately let me have it

Sorry chaps, The LSD ain't going any where but on my car!
As the refurbed calipers arrived today, it looks like I'll do the swap sooner rather than later.
Steve, what do you mean you had to get out the file and grinder?
Is there a problem in fitting the hubs through the rear uprights on the larger shafts?
Thanks for replies, guys
Andy.

As far as I have seen so far the threaded holes in the rear uprights don't line up correctly with rear disk (ie with lugs on for caliper) rear
bearing carriers.
I think I'm going to enlarge the holes in the bearing carriers, unless anyone thinks thats a bad idea

Thats exactly it...the holes dont quite line up and I had to enlarge the holes. I also had the shaft rub on the hub carrier at the back and had to
dress the hub carrier otherwise it would have grinding all the time.
I understood at the time that it was not a Tiger problem with the holes, more that the hole centres on the disk type hubs are slightly different.

I'll compare the bearing carriers when I remove the old ones.
Which bit did you have to dress?

The rear of the Tiger hub carrier. The welds on the large tube rubbed on the shaft. Might not on yours. It will be very obvious however if it does as
steel to steel makes a bit of a noise.

I used a round file to elongate some of the holes rather than drill them. This was so that the hub stayed central and there was less chance of lateral
movement.
I'll be interested to see if the two bearing carriers do have a different hole set up. So let us know when you compare the two.

Did you have to take the ABS teeth off then? I can't think why you'd need to. I'll try it tomorrow.

Hi
I,ve come to the same problem and found a few sticking points when using the stock avon rear drum upright with disk hubs.
1) The 4 holes of the hub do not line up with the tapped holes in the upright
This has aparently been solved by welding up, redrilling and tapping according to tiger. Just how you are going to drill and tap a hole 15mm? deep is
beyond my ability. You are going to need a neat flat bottom drill bit.
Whilst your at this make sure the holes are dead square around the centre hole or the drive shaft will hit. In its current state it aint pretty.
2) The Lobro shaft end is to dam big to fit in the hole. You could lathe it down taking off the ABS teeth so the sides are parallel. POINT A on
photo
3) The Lobro shaft end is to dam short to fit, when the baring is tightened up it pulls the shaft end in to meet the inside edge of the upright,
You would have to lathe some metal off POINT B off the shaft and take back the lip of metal on the inside of the upright.
After much thought I'm going to ebay my uprightd and build completly new ones base on the Luego design of a flat plate that everything is either
welded of bolted to, a vast improvement.

Hub carrier mounting holes
Looking at the photos and comparing them to my, (home made) uprights it appears that the hole spacings are the same. It looks like if you were to turn
the carrier 180 degrees the holes would line up. Unfortunately you won't be able to get the calliper on in this orientation.

i found that one hole is off centre to the rest on my dedion axle for sierra rear brakes. can you not take the brake bracket plate off and swap it to
the other side, perhaps flipping it over if necessary?
Ned.

Spinning the hub carrier round 180 degrees makes it worse....

Nope...but I would like to come up and see your rear end for meself!!
I'd also like to take measurements of your engine cradle, if I may, and, of course, return your brake flaring kit!
I'm off work now until Monday, so is there a convenient day/time I could come up? (apart from Sat afternoon - Argyle at home etc.)
Cheers,
Andy.
