Markus,
I'll give you some subjective observations since the design criteria for
the front/back braking ratios is probably lost forever.
1. The problem for me is not enough front braking.
2. Any vehicle will skid on hard cornering. If you add braking while
cornering to the equation, you've added another variable along with road
conditions, tires, power settings, speed etc. that make the problem
indescribable. I was always taught that you should brake before the turn
and accelerate through it. BTW, the changes we are talking about probably
have a negligible affect given the range of acceptable ratios.
3. I can only compare the GMC's braking to the vehicles I've driven during
the last 53 years. It's a lot better than the '41 Chevy ton and a half
truck I used to drive with 7,000 # on it and a lot worse than my Jaguars. I
just want to be able to lock all 6 wheels below 5 mph on hard pavement.
Can't do that now.
4. I've improved the rear brakes with larger cylinders. This changed the
original ratio. Maybe 80 mm calipers will return it closer to original.
5. We need to keep in mind that a lot of these things have been on the road
for 25 or so years without any brake safety problems. I'm just looking for
incremental improvements.
Enough rambling. As they say "don't worry, be happy."

Bob;
Thanks, that's exactly what I need. Some info on real world experience.
One thing I'm worried about though, If there is too much braking on the
front, then will the GMC skid whilst braking hard on corners, could we have
a
control problem? To put it another way: Did GMC purposely keep braking force
low on the fronts to maintain handling under adverse conditions?
