They’re different for a reason - the rear brakes are balanced for a lower braking force.

I have 4pots on my 90. Would not advise it, even with a bias valve it is very nervous in the wet! 02' 110 TD5 Double Cab Rebuild Thread

My old '84 90 van would lock up its rear brakes when empty - and that was with drums on the back axle!

I fitted them with the intention of using them for fiddle brakes but might end up changing back to 2-pot calipers.
Even with the weight of Blacksheep x-member, chassis reinforcement, full cage and the spare in the load bed of the truck cab, it is just too light at the back.

You can fit 02 onwards Defender 110 rear calipers and discs, they are just slightly larger.

I have a 110 brake setup on my 90. Really good stopping power but still well balanced

George - what's the difference between the 90 and 110 set up - and how ease is it to upgrade ?
I have never been happy with my 90s brakes and almost rear ended a car in Knowle today  |

Firstly, check your brake servo! Mine was cracked and leaking atmosphere into the vaccum.
Easy bolt on swap, vented fronts are the same between 90 and 110. Rear 110 discs are larger diameter and the calipers have bigger pistons 2002 90 Td5 Station Wagon

ref fiddles, I ran 110 rear calipers, twin pot as stud, with inline fiddles, worked well. in fact front locker and fiddles and it went alot of places.
or use two sets of calipers on rear, one for fiddles on on std system Cheers James 110 XS Utility 130 Puma Station wagon/camper (in the making) 90 Puma Hardtop |
