Hi Hedd (in the main)
The Girling brakes with same length levers have much greater effective leverage so the same movement has less effect. Mixed uncompensated sytems are a therefore a puzzle, even when the front axle is well located.
My RP in the 1960s with linings sold for Sevens years earlier had poor brakes. My father had changed linings not due to wear but to counter grabbing. In mountainous Wellington city several side roads feed very steeply into main routes. The Seven would slow from a reckless 30 mph but would not completely stop irrespective of pressure!
Heavy main road Sunday afternoon traffic used to maintain 50 mph and I could keep up on the flat but I had to constantly fall back to allow space.
With all semi Girling the pressure was still high so decel not so obvious to the driver. But passengers would place their hands on the dashboard for support. The early radius rods would cause the front axle to shudder until substituted. Never locked a wheel in the dry!
With high chassis cars cable alignment for Girlings is improved (but not ideal) if rear levers are upside down with cams sorted to suit. The arrangement I adopted.
