An improved brake pressure proportioning unit of the kind responsive to centrifugal force developed by a turning vehicle and having two separate weight-activated levers controlling the springs that determine the pressure reduction setpoints of two proportioning valves, utilizes a link to connect the separate levers outside the pressure boundaries for automatically equalizing the exerting forces of the springs and permitting manual adjustment of the biasing of the springs a like amount. Also, an improved brake pressure proportioning unit of the abovementioned kind uses a single weight and lever mechanism for equalizing the absolute magnitude of changes in the working length of both springs during a turn, the change in one spring being an increase and the change in the other being a decrease in working length.
