i am thinking about changing to a hydraulic hand brake set up , but don't know a great deal about them any help would be good thanks
is it a case of just buying a kit then piping it up?
what callipers do you need to use ? could 4pots ie brembo or that sort be used?
how dose it pipe up so the foot brake works and the hand brake works?
do you put a T piece in somewhere?
thanks all

the standard rear calipers would be fine for road use, they'll lock up no prob with a hyd handbrake,
especialy on a p100 as the back end will be quite light
as for plumbing it up
use the original single brake line heading to the rear brakes to feed the handbrake master cylinder
then the pipe coming out of this goes to the rear original t-piece
this lets the footbrake still work as normal but a quick tug at te lever will lock up the rear wheels no prob

thanks for the info sounds surprisingly easy lol , imo I would say the p100 will be heavier over the rear axle than a sierra if not near the same as they look light but there not really (big chassis heavy gauge used too and the back tub has a fair bit of weight in it lol )
so I am guessing so I can pass an MOT with the hydraulic set up it needs to be a ratchet type hand brake , or is there other things too?

needs to be a mechanical brake set up i.e cables etc
purely hydraulic wont pass an (legit) mot

as for weight i think it'll be lighter but it dont matter, i done an estate and it locks up no prob

ah that's not too good
and at some point I want to get it weighted and see whats going on as I think there around 200kg more than a sierra and its only really from the back of the cab back that's different so no idea lol
