No, meant as compliment, information supplied complete and accurate, not always available in these pages.
how right u are, before i replaced the discs on my hippo i soon found out i couldn't measure it correctly , due to the lip on the discs
got some old round fridge magnets, put them on the disc , took the measurement , then subtracted the thickness of the magnets

Getting a little more practical about the subject, the specs already given show an allowance for a 3 mm reduction in plate thickness due to wear in use, properly maintained brakes and in particular brake calipers would mean an allowance of 1.5 mm each side of the disk.
What I'm trying to say here is that if you have an appreciable lip on the edge of a disk which can be easily felt with the finger, then it's probably time to start thinking about replacement disks.
thks, on quick inspection i can see the lip on the discs already
but will be taking all the wheels off for a far better look , along with measuring the discs for actual wear
discs look original, 98,000 miles but can't be sure
will most likely replace all of them in the spring
inc the brake hoses as well, brake fluid change and calliper inspection
got to take the rear discs off anyway to inspect and clean the handbrake shoes
if i replace the lot i won't have to worry about them for a few years then
always prefer to replace brake items well in advance, so i know there working correctly and all done properly
will ensure they are all oem parts and replace like for like, being the ventilated discs
fingers crossed i won't have to replace the handbrake shoes, as they look pigs to do ,

Thinking about the way that the handbrake works on most Land Rovers, the brake drum and shoes on the rear prop shaft rather than on the wheels would tend to suggest that wear isn't going to be the greater problem, which in most cases can be adjusted out. The greater problem is more likely to be a seized system, either in the drum or the external operating mechanism, or in the case of the D3, I believe, a failure in the electrical system operating the brake.

Wish it was still the same set up but on the Disco 3 the Electronic Handbrake has shoes inside the rear discs and works on that via an actuator that seems to go wrong at the drop of a hat

Mine isnt working, just the red warning flashing away.
Will sort it after the winter, I'm not lying under the bloody motor in this weather

That was the "unofficial" advice from Lotus about the crap handbrake on the 60s Elan. It was so ridiculously bad that the advice was "Adjust it to work for the MoT and use the gears for the rest of the year".
Had drilled stainless discs on my BMW R1000's, it was there to help shed water off the disc surface. Problem then was that the discs wore in a ridged pattern, which is why later drill patterns had the holes in a spiral pattern.
As far as our D2's go, we buy standard OEM discs and Mintex pads, never had any issues and never really needed anything extra. I can lock the wheels and bring the ABS into play on a dry road, that's about as good as it gets.

cheers ref the info, also been reading where drilled discs can get a hairline crack between the drilled holes
will stick to the ventilated ones and replace as per oem
wondering though how good some of the so called improved brake pads are better than oem pads
being an auto i just don't bother using the handbrake if i'm honest
does seem on reading how they are adjusted and removed that a lot of dust builds up on the shoes and causing the brakes to bind
also they are supposed to be the brake shoes from hell to remove and replace,
something with being an octopus in trying to get the springs and shoes all back in one go, lol
don't use mine either , mot is due in july so gives me some time to strip everything down, replace as required
tried mine when i was buying the landy to ensure it worked ok, not used it since, lol
