9 inch disk brake conversion

[ShaneJ]

Ladies and germs I am thinking about fitting an F100 9 inch to my bedford but first I want to remove the drums and fit disks.

To make my life a little easier, can anyone offer any information? The best rotors and calipers to use etc?

I'll also be changing the stud pattern from 5.5" to 4.5" PCD.

G'day

I have a 9" conversion from Adrian Selemeyer at Castlemaine that works very well.

hoppers stoppers do a conversion too, not sure how much it costs, but the bloke there told me that the f100 drums im using are actually better brakes than the conversion will be, not sure about the CRS kit tho, i might shoot them an email and ask.

yeah the disc brake conversion works but it's not that fantastic, we have disc's all round but the conversion is just shitty single pots. I am measuring up the brakes on my ss the next time I get round to it and see if they bolt up to the beddy. I will keep you guys posted and let you know how I go

[MaTTe]

when i spoke in depth with the bloke at Hoppers stoppers, he said i was much better off getting the twin pot setup for the front than doing the rears as the fornt does 70% of the braking, which is true.. the discs on the rear may well be better than drums on a holden diff, or bedford diff.. but the f100 drums are pretty good, and they're large, plus rated for similar weight to the bedford.

[Jason 253 CF]

Yeah I agree with that that's why I want to try get vt front calapers because they are ment to be the best bang for your buck in the twin pots. But if you have f100 rear drums stick with them the seem to pull up heaps beter than disc's on the rear

rocket is playing with volvo 4 piston fronts...

i have had wb rear calipers and rotors on a 12bolt chev diff. works well but i would like to play with bigger bore on master cylinder after talking to trev..

i would go for disks after having them.. very reliable.

i have a 9 inch here. its been had the housing cut and welded + modded for holden brearings + wb disc brakes.. seems like a very good conversion + it all looks very standard..

It took me about 4 years to get my 4 wheel disk conversion to work to the point that I was happy. I am at present running WB statesman brakes all around but the front calipers are cast iron not alloy (to many problems).I run a HQ brake proportioning valve with a 1" bore falcon master cylinder & Ford double diaphragm booster. I found by changing brands of pads would affect whether the rear wheels would lock up before the front or not (also depended what sort of load I had on board--anything up to 7 adults). I do not suffer any brake fade under normal driving conditions even when driving down from the snow fields (the brakes sometimes get very smelly when pushing along a bit faster though). I am at present looking at installing volvo 4 pots but I cannot afford to take the van off the road long enough to carry out the task. I quiet often tow a tandem car trailer & the brakes cope with this well (one time the trailer brakes had failed & it still coped). WB rear discs & calipers are hard to come by now so one might have to try & adapt Falcon rear discs.

i was told the wb rear discs are still easy to come by new by a brake guy the other day..

I can buy the disks on ebay, but it's the calipers & parts for them that is hard to get.
