I didn't even know a disco one would fit - either way not worth experimenting with. I think a "salisbury" is what you're after if you decide to change the whole axle. Though keeping your own axle sounds like a good idea as getting an old axle with unknown innards could be dodgy - in my case the diff was so worn and leaking anyway that anything would have been better, and as it turns out it was a huge improvement, not just for the brakes!

PS I wondered about whether there might be a pressure equalizing valve between front and rear systems, or whether one was needed and whether anything else would need to be changed... got conflicting advice, but in the end I didn't change anything at all, just plumbed in the 3-way union at the top of the diff casing exactly as the previous one had been, bled the brakes and they were instantly brilliant, no further tweaking necessary.

A 90/disco/rrc rear axle will bolt staright onto a 110 with a different prop, but as has been said they're not rated for the weight of a 110. Rear disks would be nice but along way down the priority list.

i fitted a disc brake axle to my 110 1989 v8. the easiest thing to do is get hold of a range rover rear axle which is has disc brakes as standard. the axle will fit straight on to the 110. the ONLY mod you will have to do is alter the length of the prop shaft to suit. i had to do this as my origional axle was a sailsbury, and the range rover replacement axle wasnt a sailsbury. to get the prop altered should be £50 - £80, no more. once you have the disc brakes fitted, you will notice a difference compared to the standard drum brakes - a well worh mod indead.

As mentioned before, RRC axles are not rated for the weight of the 110. Whilst i'm sure they work fine, if you have an accident that results in an insurance/police inspection, there is a strong chance the insurance could be invalid as an incorrect part has been used. A salisbury should be replaced with another salisbury (or perhaps a later TD5 axle if i have read other posts correctly).

Edit - VB beat me to it!

yes anything factory fitted to a 110 can be fitted to any other 110.

Thanks for confirming...... i meant TD5 110, not any old TD5 above!

The number of people that think it is ok to use disco alloy wheels on 110s also amazes me - it should be published more widely that some of these conversions are incorrect. Too many mods are carried out in a haphazard way that could result in unroadworthy and potentially dangerous vehicles......you only have to search back through this forum to see what can happen (sadly).

I agree completely, however i know of at least two landy "specialists" that have fitted disco alloys to 110's they've had for sale to make them look nicer on the forcourt.
