I'm a bit sceptical about brake fluid boiling.
I have sat at rally controlls in the middle of the forest and seen car after car come in with disks glowing red or
orange.
The most likley reason for brake fade is the pads overheating....and standard pads, just like drum linings are very much prone to brake fade.
The american engineered cars ( ford / holden ect) have been less inclined to have high temp pads from standard because they consider their customers want a soft brake pedal so they install soft pads and lingings....and if you are taliking about factory Fords and Holdens.....their brake systems are not wonderfull..so don't use them as an example.
Its very true that many vehicles have disk brakes on the rear..not because it gives a better result but because it is a sales point.
The biggest issue with rear disks, is the piss poor hand brake.
All that said..let me tell you a properly engineered and maintained 4 wheel disk brake system will piss all over a disk drum system in every situation.
As for power steering....yeh back to the ford and holden problem......cheap scates that didn't spec a big enough power steer pump......they didn't spec a big enough oil pump in the sump either.
Both 4 wheel disks and power steeing are used in competition motor vehicles with little incident.
who wants to go back to armstrong steering.......
I grew up in fast rearwheel drive 4 cylinder cars and none of them had power steering.... and none realy needed it...but they all weighed in
well under the tonne.
see how you go driving a 3.5 tonne 4wd without power steering, particularly off road.
Anybody driven a stock 40 series lately.
