I've noticed on the 2012 FFRR and maybe other years the same too, but front brake calipers on some are small bodied single piston brake calipers and others have a large bodied 6 piston caliper.

Why did LR do this and what model variants had the two types? Was it an option? Seems a retro step to go single piston for a car needing pretty healthy braking capacity.

I hope someone knows about this one?

The naturally aspirated 5.0 has the 3.0 D4/RRS 2-piston calipers.

When Land Rover brought out the last major upgrade to the Range Rover with the TFT screen the 3.6 TDV8 ( and apparently the 5L N/A ) were " down graded"to the sliding calliper brakes but the new SC 5L was given the six pot Brembo's ,then a year later when he 4.4 TDV8 came out with the 8 speed "box" Land Rover could announce a brake upgrade across the range . Bad call but good marketing . 2008 MY Supercharged

As above

All 2009my> TFT screened 3.6's lost Brembo brakes...
JLR upgraded to 6 pot Brembo's with the release of the 4.4TDV8 engine in 2011...

So, either you are incorrect in the 2012my sir or it took a year to filter down under?

Microcat shows the 2-pot calipers for all 2010-2012 with na 5.0 engines.

Edit: Here's the VIN SALLMAMD3CA362633 of one for sale at the moment that from pictures is obvious that it doesn't have the Brembos fitted to the 4.4 TDV8

That'll be the 2012my which was released in 2011 sir

MY12 still built up to about the end of June 2012 with some sold here until at least the end of 2012. Hence the OP's observations are not unexpected.

Right sir! When was the 4.4TDV8 released to market? As that will give you an exact date when the 6pot Brembo's were installed across the range...

The 4.4 TDV8 was available in a Sept 2010 built MY11 eg SALLMAMH3BA336273 yet my supplied VIN above is for an August 2011 built MY12 na 5.0 without Brembos, as observed from pictures that are supposed to be of the same vehicle as the VIN. Hence I can't see how "Brembos across the range" can coincide with the release of the 4.4 TDV8 unless in practice the UK did not get the na 5.0.

Crispy, thanks for opening the discussion on this topic. Looking at upgrading from a 3.6TDV8 to a later model 322 (SWMBO has a distinct preference for the "boxy shaped range rovers". Towing our caravan, which weighs in at about 3.1T fully laden, I am super impressed by the TDV8, so while e heart says SC, the mind says TDV8. So... Looking at late model 322 4.4's. Towing a decent weight van, looking to make sure the tug has adequate stopping power! Pi wasn't aware the TDV8 had lost the brembo a at some point, so keeping a watchful eye on this one.

No probs BP, thanks to others above for input. Will look out for this one day when SC upgrade required.
