The caliper has to be rotated a bit, otherwise it will foul on the leaf springs.. :( Then you will have to fit the statesman handbrake cables...

You will also need to fit the statesman master cylinder aswell...

Hope that helps..

Damn it!!! HK beat me to it.. Lol

Statesman diffs AREN'T wider, exactly the same width flange to flage as any other HQ-WB diff (disc or drum). Disc brake axles are shorter to allow for the disc thickness.

That is correct about rotating the calipers. Or fit lowering blocks.

You just have to modify the disc/drum cylinder to operate the discs, no need to change the cylinder.

I still reckon the drums are better and lower maintenance than HZ-WB discs.

Are you sure you dont have to change the master cylinder

Yep, waste of time. When you hit the anchors hard in these things all the weight transfers over the front wheels and the rear brakes do about as much work as a federal politician. If you're going to spend money on brakes then upgrade your fronts instead. Rear Disc Brakes look good in a For Sale ad but won't be much benefit in a van.

Thats why i got rid of my disc brake rear end for that reason it would take to long to pull up

yep you do. or put a reducing pressure valve in the flare of the rear brake line of the master cyclinder

Drums on the back are still current on a new hilux, so why go to the drama of fitting them to a hq-wb commercial? Agree that upgrading front brakes would money better spent.

Are you sure about this being a waste of time, disc brake on the rear. My hx panel van had disc brake (wb disc brake diff) fitted on way before I purchase the van. To be honest, best set of brake, good braking control and pull up very quickly. Better brakes than my hz ute (which has rear drums) and also the LE coupe I own (rear drum brake also). HZ GTS I have also (rear disc brake - which was standard), very good braking and control. Personally, I would think the panel van would have enough weigh over or at the rear end and wind factor (van are not the most aerodynamic cars) that rear disc brake would work very well. Let say, fitting rear disc brake to a ute, lite in the rear end and more aerodynamic, the weigh transfer you are talking about, I can understand and agree that rear disc brake could be a waste of time. All I can say personally, disc brake work very well on my panel van and I have decided to leave them on.

my tow vehicle is a WB stato, and the 4 wheel disks help alot when towing car trailers - gives me alot more confidence approaching roundabouts etc.

Drums are actually better at braking than discs...but only for a few high speed stops until they get hot, then they lose efficency. That is where discs excell, at repeated high stops, disapate heat better. So unless you're doing track work I'd stick with drums at the rear.
