Has anyone upgraded the standard B40 single pot callipers for the Pajero 4 piston units, have been told it’s a straight swap with the bigger discs also from Pajero?

Anyone?

Also curious. I have tried all sorts of disc and pad upgrade for my 2011 Barbarian but the brakes are undersized for the weight of the pick up. I was wondering if the earlier 4 pot calipers and 315mm discs would fit and improve the braking?

Or the 332mm 4 pot brakes from the Shogun 3.2 LWB?
