It occurs to me that the gent who asked about progressive brake bias
should look at the front-wheel-drive pickups that Dodge was building
from K-car bits several years back. These had a proportioning valve
connected via a lever to the rear suspension. More load? More rear
bias. Front end diving? Less bias.
>>My '83 Audi Coupe utilises the same thing, although
after RTFM I would *never* dream of fooling with the
adjustment.
FYI, the Riley ('48 RMA 1 1/2 litre) utilises a
peculiar braking arrangement with hydraulic fronts and
mechanical rears. If I remember correctly (Martin
Frankford pls. correct me), the master cylinder
"floats" skewer-like, on the activation rod from the
pedal entering the front side, and the rear of the
master connected rigidly to a rod that attaches to
the rear brake linkage.
When the pedal is depressed, the rod forces the
piston into the master cylinder (as usual), which then
transfers the force to the master cylinder body,
causing it to move rearward, which in turn acts on the
rear brake activation rod and associated linkage.
