Subject: Rear brakes - '87 5kTQ
that lever/spring thing is, i believe, the component that adjusts
hydraulic pressure for the rear brakes to compensate for unloading
the rear suspension during the forward weight shift under braking.
the lever moves as the trailing arm pivots and actuates a valve.
this thing must be readjusted when lowering the suspension to
accomodate the modified suspension geometry. otherwise, it will take
a much greater weight shift to activate the valve operator, which
means too much rear brake bias. (best case = smoke show; worst case =
severe pucker and worse)
