so am i dreaming?
you get a valiant rotor (why valiant?)
(http://i251.photobucket.com/albums/gg287/hughreid/9720_1.jpg)
and machine it to fit on a bedford stub (why not holden ???maybe holden calipers wont fit inside 6 stud wheel)
then you get someone clever to make a hub conversion
(http://i251.photobucket.com/albums/gg287/hughreid/ichiba_rear1.jpg)
bolt it all togeather and youŕe off to the engineers for a cert?????? ???
-
isn't valiant the same as ford?
what about a nissan suv or something for disc's, they are 6 stud
-
yeah, too many options.
just trying to get a tried and tested option because you could spend a long time on testing every rotor.
That sweet LWB that i can't afford used valiant rotors and he had a hub made.
I was at the wrecker today and those six stud drums are HUGE :o,
so depth is not an issue, just getting rotors inside the wheels.
Need to find out if holden will fit as i can use the caliper brackets of the standard disc conversion
-
G'day
Remember that the Transit has disc brakes and is the same 6 stud pattern.
The 1984 lwb Transit has ventiated discs.
-
yeah, but i can't find them -dba and reliance and a few others don't list them, and i haven't found one in a wreckers yet
I'm still hunting, if you can recommend a source.........
-
not sure why val, the look great disks though that might be why.
, barry,s has commadore calipers.

Here are some photos to rev up the discussion.
I was told that the Transit disc setup could be fitted to a CFL, however the offsets look wrong.
Maybe the CFL hub can be machined to have a setup something like the 1984 Transit.
Standard Bedford Drum Brake:
(http://i209.photobucket.com/albums/bb11/blackbedford/DSCF1567-s.jpg)
Early Transit solid disc front end. The van had a Falcon 6 motor and single wheel rear end:
(http://i209.photobucket.com/albums/bb11/blackbedford/DSCF1565-s.jpg)
1984 Transit ventilated disc. The van had a Falcon 6 motor and dual wheel rear end:
(http://i209.photobucket.com/albums/bb11/blackbedford/DSCF1568-s.jpg)

is the bedford drum deeper than the transit rotor ?
if so then a spacer would bring it out enough?
Without one of each on stub axles there's not much i can work out.
Will have to try JB's in dandenong, he does transits and bedfords,
-
Phoned JB,
yeah sure no problem i can tell you.
Transit have smaller studs, but same pattern. didn't know about drilling to bedford studs.
He says he can give the bearing no. to bolt straight on, ???
Rotors $110 s/h each
Calipers $220 each (2 pot)
Make your own mounting plate.
Can't understand why no-one does it.
Still not sure, bound to be a few glitches on the way
Hmmmm, now all i need is a six stud LWB with a Hwy diff ;D
Anyone wanna swap a SWB with discs and diff?
Hardly ever gives any trouble ::)
-
G'day
Did JB happen to say which model Transit discs he uses?
-
no, i´ĺl go out and see him (next week i hope).
I doubt it will be as easy as he says,
He has a strong accent and a cheep phone :D so i only got about half of the conversation.
He did say it is a ventilated disc though.
There´s a stub axle / hub in a wreckers out his way so i can get both on the same trip
sure hope that van turns up ;D

How did you get on with JB's?
I now have an urgent need for a set of CFL 6 stud discs. I want to fit them before I get the Engineers inspection done on the dual cab.

i still have a lwb hwy diff here with a salsbury centre, ive been hanging on to it just for you hugh:)

i have a h/way diff now, it's the rest of the van that i'm not to happy about......
it's all on hold till my health and income picks up :(
-
oh yeh silly me.
ok anyone else wanna buy it seeing hugh doesnt want it anymore? price redcution for QUICK sale From $700 to $600!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Quick sale!!!!!! haha

today l went to Brooklyn to a mechanical engineer (vicroads approved) for the boss, we deal with this bloke all the time, so l thought l would hit him up for some info on what l have to do to make the beddy in to a v8 legal, l feel over backwards when he told me that in November they changed all the rules
mounts and everything is basicly the same, BUT THE BRAKES
They have to match the carring capasity, so HQ & HZ are out cos they only made a 2 tonner, so are the conversion that use the ford disc's cos there off a mere car......
According to the info in facts and figures a CF350 has the carring capsity of 3.5 tonn., that means l have to use the disc's of a late model bedford or a Ford F350, or something else that has the carring capasity of 3.50 tonn.
l hope this is wrong.
-
G'day
That could be right as that is what I have been told has to happen in NSW.
-
so what was the '84 dual wheel transit rated for?
must have been similar
-

It would have been about the same.
-
wow, thats not good!!!
tell me will hz brakes be sufficent for a SWB.
ben
-
lf the carring capasity is over 2 tonn.....................
-
im not sure what the carrying capacity is of a swb. anyone know? so is that inc the weight of the vehicle as well? or just how much weight it can carry.
cheers
ben

Ben
An old manual I have lists a HQ as weighing 1.4 tonnes
Bedforfs came in different weight capacities look at the Chassis Numbers
The first 2 (97) indicate that it is a CF
The next 2 the carrying capacity
1=14/18 cwt, 3= 22cwt, 5=25cwt,7=35 cwt
! cwt = 112 lbs= 49.7 kg approx
1=.94 tonns 3= 1.09 tonnes,5=1.25 tonnes, 7=1.73 tonnes the weight of the vehicle then has to be added on
These figures came from the old BUGA site
Cheers

so what did the people doing the conversion end up doing, and was the cost?
was the main reason for not wanting to do the holden conversion the stud pattern change or is there other issues such as load or offset changes.
cheers
-
I'm not aware of any reluctance to swap to HQ discs.
Its a question of whether it is safe to turn down the CF axle (which I believe is illegal anyway), or to enlarge the bearing capacity of the rotors.
There is a bit of stuffing around making adapters to hold the callipers, but overall a simple conversion.
The rear axles can be re studded quite easily, for uniformity.

A few thoughts on disc brakes:
Properly adjusted drum brakes are very efficient, the problem is keeping them properly adjusted. Poorly adjusted drum brakes can be a bit scary, especially at speed.
Drum brakes suffer heat fade under heavy use and dont work well when wet.
The RTA require disc brakes fitted with a V8 conversion and for the conversion to be Engineer approved. The issues include the method of adapting the disc and caliper; and the load rating of the hub.
Having to carry 2 spares is an issue, especially running around the outback. Having the same rims all round would be good.
-
the person thinking of the conversion has access to a pair of stub axles off a SWB already fitted with holden brakes. I'm quessing these should fit straight on. I wasn't to sure with the van being a LWB and having 6 stud wheels.
The original drums are over size and the wheel cylinders are leaking major overhall is needed anyways.
-
Ahh, you didn't say it was a twin rear wheel model.
I THINK the stubs will fit, but he will need two spare wheels.
He may have trouble getting it certified though, as I believe the CF350 has thicker stub axles than the others, and if so he would be making it weaker than before.

i have a lwb front end here. the stub axels are the same size as early swb (also same bearings too) which is smaller than later swb.
what im not sure about is whether this front end came from an early lwb or a late lwb. and if the lwb stub axels changed diameter at the same time the swb did. (74)

I am bumping this one up.
Has anybody come up with a solution yet?
Regards
-
nope, mines just rusting quietly in the drive ;)
-
Does anyone have a year or model or contact for the Transit disks and calipers? Do they fit the LWB.

With the info provided by MR C, I contacted Kevin at Penrith, who put me onto Race Brakes at Wetherill Park:
http://www.racebrakessydney.com.au/ (http://www.racebrakessydney.com.au/)
I had a talk to Matt and have sent him a detailed inquiry about CFL disc brakes.
Fingers crossed, we may finally have a solution.
Is anyone else still interested in getting a 6 stud disc brake conversion?
I would anticipate that the more people, the cheaper we can haggle a deal.
Regards

Just thought id stick my nose in [yous know I like this sort of shit] does anyone know what the 6 stud bedy matches [ Transit=Toyota crusa or any other 6 stud wheels ] I originally wanted a LWB camper so would have discs on it by now Cheers Reid

As far as I know the only other vehicle with the same stud pattern is the early Transit. I haven't found anything else.
