Abstract
A brake control apparatus for automotive vehicles is provided which has two separate hydraulic brake lines leading to wheel cylinders and performs a brake assisting operation to hold the wheel cylinder pressure higher than the master cylinder pressure in each of the hydraulic brake lines when a brake pedal is depressed by a vehicle operator. The brake control apparatus also includes a fluid pressure difference regulator which regulates a pressure difference between the two hydraulic brake lines so as to fall within a given allowable pressure range, thereby minimizing adverse effects on the brake assisting operation which are caused by electric and/or mechanical performance difference between the two hydraulic brake lines.
