Braking force distribution

[damusto]

OK thanks Ivan, I find it difficult to say are these methods easy or not.
Therefore I will leave the estimation for You.

Method 1:
Scan the graph with description of accurate service book.
I have one from 1983 - and it doesnt contain such information, not even a mention of proportioning valves ! Oldeskewltoy has one from 1986, He was here, said nothing, so I think that his edition doesnt contain this also. So I find it difficult, but in few next days I should get Haynes SM, maybe it will change something...

if not another method:
Connect manometer in to right place in your braking system, and write down the corresponding readings. This is kinda fun, You need to take into account bleeding the system and the whole fuss with liquids.

Method 3:
Periodic testing of the vehicle.
In Poland we have such stations


No. 4 is for brakes test

This way You get braking torque on axles


So it is possible that You have this in papers but didnt pay any attention, because the car was allowed to traffic.
Of course We have to take into account differences in the size of discs and pads area, but that is not a problem.

Method 4:
This can be costly, professional dyno and detailed analysis.
Stack of printed works with curves and graphs...

But I dont want anyone caught up in the expenses, of course.
Is any of these methods seem like easy enough ?
