brake upgrades just don't get it :-)
I have standard brakes , if i want to stop , i press em , if i want to stop quickly i press em hard. The minute i do that dry road , wet road etc , i exceed the capabilities of the tyres and the abs kicks in. So what does V8 brakes or brembos actually give me apart from some bling or bragging rights. I understand brake fade etc and feel as i ride a motorbike with brembos but in terms of actual braking distance how if standard exceeds the grip the tyre provides how does any of the upgrades help in actual stopping distance in a one off emergency.
Just had a few beers and thinking it over!
Cheers

If you are braking to the limit of the road/tyre/ABS combination then bigger brakes do nothing more than shed the heat quicker whilst achieving the same overall stopping distance.
The problem with the original small brakes is that they can and do suffer from brake fade, especially when the car is laden and/or conducting sequential and large braking events. In this situation the braking distance can grow at an alarming rate.
The 'V8' brakes make a considerable difference and given the price to upgrade (effectively the price of the calliper brackets) moving to them when replacing the disc should be a no-brainer. Thankfully LR addressed the braking issue with the launch of D4, which has brakes larger than that of the D3 V8 upgrade.

I just upgraded the front and rear to V8 discs. And the braking is nite and day to standard, the standard Discovery 3 is well under braked for the size and weight of the vehicle.

+1 for me too.
My fronts were a mess with worn pads, discs, and a stuck caliper.
Got the V8 upgrade kit from AF and my word they are excellent.
It gives you real confidence you can bring the beast to a stop on a sixpence.
Granted id been nursing my fronts for a bit but this is a step change for very little extra money.
Highly recommended upgrade.

I was in the same boat Dave, the discs and pads where wrecked and I wanted to make sure I was happy with the braking this time around.

<EDIT> Of course doing an upgrade will increase capability but that doesn't mean that the original set-up was wrong. 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021

Bobs it's all there on the website.
I added front calipers too as I wanted the whole lot changed.

I did the V8 conversion a couple of years ago, I agree that the standard brakes will stop you and in the once or twice I actually had to conduct an emergency stop they worked pretty effectively so this restored my faith in the effectiveness if the standard set up,
The descision to go V8 when the standards wore out had already been made at this point, as others have said the difference is impressive.
Most importantly for me pedal feel improved, I lost the spongy first application of the braking which the standard set up had, the V8's need dabbing where as the standards required standing on.
I felt uneasy with the lack of feedback from the brakes, and as mentioned above they suffered from brake fade, something which I hate !
Towing a trailer down the Buttertubs pass with poor brakes isn't a pleasant experience Only dead fish go with the Flow !

Bobs you will require calliper carriers and not callipers, the carriers space the calliper away from the hub and allow for a larger diameter braking surface, this then requires new discs.
Standard pads are then required because you are on your original callipers, if fitting new V8 disks you really need new pads In there or you risk getting the new disks damaged with old pads.
I can reccomend the EBC yellow pads and EBC drilled & grooved disks.
They work very well.

im sure I read somewhere many years ago that the braking distance of the D3 was better than many other vehicles in the same class and also of those smaller/lighterDuncan

The standard TDV6 setup is barely adequate, IMHO.
I had a few "moments" when slowing from reasonable speeds, the car just felt like it was not going to slow down. They gave very little confidence when braking, and had to plan your braking well in advance. Would not have liked to be in a position to have to use them in an emergency...
I could have gone for the tried and tested V8 upgrade. However, I was offered (and bought) a pair of Brembo calipers for not a lot of money, a good set of Drilled + Groove discs, and a bargain on a set of EBC Redstuff pads.
And being my company car, it acts as an advertising tool. The Brembo's do generate a lot of interest, both from forum members, and non-forum members
Now, when you press the pedal, you KNOW the car will stop
I have standard brakes , if i want to stop , i press em , if i want to stop quickly i press em hard. The minute i do that dry road , wet road etc , i exceed the capabilities of the tyres and the abs kicks in.....
Have to agree here.....really dependes how quick you have to stop (keep yer distance...!!!)

the standard brakes to me are good when all wear parts re done....for approx 25 - 28 k miles wtith my journies & driving style...then things definateley fade away where you have to pressvery hard & the brake distance is extended...can be a bit scary...D3's as standard are underbraked...in a panic stop.
So being able to prevent this & maybe have a longer life - doesnt get toa scary stste is worth it if you have the option...I reckon I had the option when I replaced my calipers (front)....I have driven one with V8 brakes...there is a marked differenceBREXIT - done properly.
