Thread: Disc Brake Conversion.

I once looked into fitting the rear disks and calipers off the new 78 series Land Cruiser onto the front of a Series, as on the Cruiser the disk slips over the hub. The Cruiser disk is also 5 stud so could easily be re-drilled for Land Rover stud pattern and then slipped over the series hub. The offset looked good (for wheel and swivel housing clearance). The disk diameter was 345mm from memory. The swept area on this set up is quite small, however the large radius would give good braking effect and heat dissipation. It would use a similar adapter but avoid the hub problems. If it worked the only down side I could see would be that the disk would be inboard of the wheel and vulnerable to damage. Disco 3 disks are also slip over hub design. Just my 2cents worth

The best idea would be for me to send this bracket to someone who can measure it directly and convert it to CAD.

I just measured the internal diameter, it is 94mm not 90mm.

The attached photo will give you an idea of it's size.

The plate bolts onto the outside of the hub stub in place of the drum brake base. The disc rotor bolts to the inside of the hub, not over the top. They also came with wheel spacers sitting on top of the hub.

I'm working 12 hour days until Monday, I'll take some photos of it fitted to the swivel assembly then and also send the bracket off to be "CAD'd".

Hey aren't CAD drawings a programe for those computer controled machines..

Anyway TJ i will put what i can to the cost as i realy want to get the plans/drawing to get started on getting all the parts ..

I also want to convert the rear sals to disc aswell so it will be disc alround..

This is an excellent idea. I'm going to try this on my 109" as I have a second set of 6cyl front brakes now. I only have a single line system, but I'm thinking that using the front brakes on the rear while going forward will probably have about the same stopping power as the original rears.

......

CAD - computer aided design (or drawing) - drawings by computer
CAM - computer aided manufacturing - machine controlled by computer

CAD/CAM - put the two together - design on computer and these designs in digital form run the machine.

UM so any progress on the BRACKETS..
I am going to get me some 12mm plate this week i hope...

I dropped it off to Agrojnr today, he's going to CAD it and look at the possibility of making a copy.

Is there a smiley here for a handball?

Hey i was just thinking , wondering if i do this conversion will i be able to keep & use my 15 x 8 rims & tyres , Will they fit over the calipers ????
