Gday guys has anyone ever done this? Or something like it. Im looking for an easy and cheap option sticking with a Ford bolt pattern which I think the Volvo must have.


Thanks

I'm pretty sure volvo is torana stud pattern, I recall a mate running volvo rims on his, or maybe it was HQ. Either way, it was Holden.

Cheers and beers

I have a couple of Volvo discs on my still under construction glass A roadster. They are off a 122 model which is late fifties/early sixties. Finding some these days could be a problem. After that model they changed from the Ford pattern (5 on 4 inch) to the smaller Holden FE to HG pattern (5 on 4 inch) and for all I know they might still be using that pattern today.

Fitting them was easy enough. The Volvo outer bearing fitted the early Ford spindle and it was just a matter of going to the local bearing shop to find a new inner bearing with the Ford inner diameter and the Volvo outer. The outer bearing has to go about 6 mm further in on the Ford spindle but that only takes a bit of minor machining to fix that.

I have yet to go looking for a grease seal but that should not be a problem.

I am using them with Datsun 200B aluminium Girlock calipers but I had to reduce the diameter of the discs by 5 mm in order to give the pads full contact and to get them in off the outer edge of the disc.

I doubt if this set up is ideal today. I bought my discs and hubs six years ago and even then they were getting scarce. Both discs were worn but they were good enough to machine down to a size that was within the legal limits for a 200B. I wanted them to reduce unsprung weight. I could not see the sense in using heavy ventilated Falcon discs, that were designed to stop a fully loaded V8 automatic station wagon weighing over 2000kg, on a little fenderless roadster. My engineer agrees and is happy with the Volvo /Datsun setup.

If I was starting again today I would do the same thing but would most likely look for something other than Volvos that are now over forty years old.

1986 Toyota Hilux 2x4 are Ford Falcon bolt pattern, may be worth a look. Not sure 'bout size of disc rotor!

Apparently Mazda pattern is same as Ford - 5 bolt on 4.5". Anyone heard of these being used?

100% correct, early holden/torana pattern, but with the larger diamater ford studs/wheel nuts. Weve put quite a few disc brake 164 volvo diffs in early holdens over the years.
Try the P76 rotors, they are ford pattern and can be adapted to the Ford spindles, the bonus is having a narrower track too.

After looking at this thread,I recall an article in an early 70,s "Rod and Custom" dealing with the adaption of Volvo discs to early Ford stubs,I am still hunting for it amongst my leftover old mags,whilst doing so I came across an article on Jag discs to the early Ford stubs,March 1973.........Frank...

Stevep ,My previous experience with an adaption to early Ford stubs was Customline drum brakes,the Ford outer bearings appear to be a fit on the stub,the inner required a machined sleeve as a press fit to the axle to take the inner bearing,you can start on this principle for your adaption of the discs,I have the feeling that others have done a disc conversion before using XW-XY discs and Holden Calipers [the Ford units have an oddball bolt up arrangement].................Frank.

Early Volvo are definitely the same as early Holden FE-HG or Torana. Late Volvo however are the same as Rover and Cadillac.

Other vehicles to use the Ford stud pattern are late Valiant, larger Toyota (Crown etc. but so does the MR2), P76. Anyone else have some more?
