So that was the reason things didn't quite line up with those calipers. I presume you're talking about the PCD of the caliper mounting holes ?

Metric vs imperial????
Checked tonight and they are 7/16 UNF, so Uninformed was on the money suggesting it might be an imperial/metric issue.
I'm surprised that they were still using imperial threads in the early '90s though.
Obviously being UNF they are still fine so my statement earlier about them being coarse thread was incorrect. Think I was getting myself confused with County front calipers (which ARE coarse). Basic fact is the same though - early and late D1 bolts are different ;)

Just a bit of trivia, on my County the disc brakes use the imperial system for fastenings whilst the drums are metric...
Land Rover logic at work...
Has anyone ever used the ventilated front rotors for a rear conversion?
I know that when I changed my RRc fronts from solid to ventilated the improvement was noticable, but it could have just been the change to the later callipers making the difference.
Thanks Ben
IMHO if we're going down this rear disk conversion deal, we may as well get the best we can, hence the thoughts on ventilated rears.
The Army used Land Rover 90 front callipers for their rear disk retrofit. I'm assuming the 90 calipers are 4 pot with smaller pistons than the 110/120 front callipers. Any one know the differences?
Are the 300Tdi Defender 90 front callipers the same as the ventilated rotor 110/130 callipers?
Well, we finally sorted out the caliper brackets. What we ended up with is a kit as you can see in the pictures below. We found some minor variation between vehicles and even from one end of an axle to the other, so instead of the bracket being made up of 16mm and 9mm, it's 16mm, 8mm and two shims, 1.6mm and 1mm. This allows adjustment to centre the caliper to the disk. There's also two dust shields included.
The only other things you will need to get is four M10 x 1.5 x 45 Grade 12 bolts.
The kit will be $100 + $23.60 postage Australia wide. This works out to less than half the price of genuine Defender caliper brackets, and saves the hassle of trying to match things up if you use the suggested parts as mentioned in this thread.
This price is non profit, just to cover the cost of laser cutting and my time for drilling and tapping threads.
I should point out, any of these kits sold through this thread are not a product of my business (Rijidij Off Road) and I accept no responsibility for the fitting and engineering requirements of your particular state. I have made these kits simply to help out anyone wanting to do this conversion.
If you would like to buy a set, send me a PM with your mailing address and I'll send payment details.
Cheers, Murray
