A traction control device is provided in which the valve opening pressure of the pressure relief valve is reduced to lower the hydraulic pressure generated by the pump. In this traction control device for a rear-wheel drive vehicle, the proportioning valve is positioned directly in front of the traction valve set in the main brake line that supplies pressure to the wheel cylinders of the rear wheels.

Traction control device for rear-wheel drive vehicle

A vehicle brake device is provided which enables easier mounting of the proportioning valve(s), and easier assembly and better layout of the whole brake device. An auxiliary hydraulic pressure source and traction valve are positioned on the side face of a hydraulic pressure box (70), and dumping chambers (26), auxiliary reservoirs (31) and proportioning valve(s) (24) are positioned on the bottom of the hydraulic pressure box such that the axial centers are parallel, and the proportioning valve(s) (24) is (are) arranged below the axial center of the auxiliary hydraulic pressure source and below the traction valve (23), and positioned such that brake fluid therein flows from the bottom to the top.
