Hydro brakes ?

Found lots of references that state the 4.8 callipers are "different" - but I can't find anything that tells me how many pistons they hold. I have been trying to improve my brakes for some time and 4 piston callipers would help lots - but I only want them if they bolt straight on. I don't want any adaptors or any other potential problems.

They are only 2 piston calipers. The brake pads are different but can be fitted to any other gu caliper. The rotors are different, so mountings are a little different and sourcing diff housings/assemblies would be easier than modifying your current. Im not sure that there is enough difference for an adaptor to be used.

If you have a look at the brake circuit the lsv is also a culprit in its operation to the patrol brakes effectiveness.
