B Body Disc Brake conversions
A few years ago I believe someone on here made some brackets so you could use Toyota hilux/surf discs and callipers on B Bod disc spindles.
Is this still the easiest & cheapest way to convert or is there and updated idea?

it was a conversion of its time....
the hilux brakes came off mid 90s hilux/landcruiser 75 series. they are sumitomo callipers with a 3.5 in centre lug mount.
they are 4 pot callipers, so make excellent use of their pads to provide stopping power greater than you get with a 1 pot slider calliper, and do this with a smaller rotor leaving space for 14 or 15 inch wheels and massive hilux and landcruiser tyres
other 3.5 inch lug mount callipers exist.
like Jag XJ callipers (massive and heavy)
like Austin princess I think
its a common mount on some wildwood conversion callipers as well
the beauty of the Toyota calipers was 40 quid a pair second hand and much greater clamping force than standard.
Believe both A body and B body spindles have a 3.5 inch centres lug mounting holes for the Bracket used with Mopar callipers
so the calipers bolt on if you sleeve the holes in the lugs (metric holes and imperial bolts)
trouble is on a B body the disc rotors are much bigger than the hilux rotors
so the caliper sits on the B body spindle at a position that is suitable for hilux sized rotors.
if you were to do the conversion on an A body the disc rotors are smaller and only need 3-4 mm taking off the diameter in a lathe i.e you removed the dead space not swept by mopar disk brakes and off you go
think B body discs rotors are about 1 inch bigger hence on Antons conversion brackets were used
it was a common conversion in Oz due to a lack of spares for the Kelsey Hays PIN slider calipers used from 69 -72 and the reasonably dramatic increase in stopping power you got for the cost of 2 second hand callipers 2 special brake lines (mopar to metric) and a few days mucking about
however for a good while in the past 10 years the Aussie dollar matched the US dollar so people over there tended to get US conversions shipped in, it suddenly became cheaper to ship from the US and its nicer to fit new brakes than clean and rebuild old 1990s brakes
I think Australian VJ valiant calipers and aussie hubs and rotors would work
the disc is about the right size for the Toyota caliper and the Toyota caliper was designed to stop a big old modern Toyota of 3200LB or about 1.4 tonne unloaded the landcruiser topped 2 tonne. I'd use landcruiser callipers
95-2002 70, 75, 78, series
the Aussie VJ-VK Girlock set up would be the cheapest its not like the US where so many card didn't have disc brakes. all of them did from 69 onwards
but they are A body sized so you can't use the spindles. but you do have a Hub rotor bracket calliper set you could try off your aussie hard top (if the VH set up off the hard top works and VJ will)

Made my own kit
Used-
78 Cordoba discs
Spindle spacer from 'Dr Diff'
Landrover Defender 4 pot calipers
Had a caliper mount machined up by an engineering company and spacers made thicker so the calipers will fit over the discs
Fitted braided lines
Also added a servo
My thinking was that it will stop a fully laden 3ton LR then it will stop my car
IT STOPS REALLY WELL
