ABSTRACT:
A brake control apparatus includes a brake unit. The brake unit includes: a first port set hydraulically connected to a master cylinder via a first fluid line set; a second port set hydraulically connected to a wheel cylinder set via a second fluid line set; a first fluid passage hydraulically connecting the first port set to the second port set; a first switching valve arranged to vary a state of fluid communication through the first fluid passage; a fluid pressure source arranged to produce a fluid pressure supplied to the second port set; a fluid accommodating section adapted to accommodate a variable amount of brake fluid; a branch fluid passage hydraulically connecting the first port set to the fluid accommodating section; and a second switching valve arranged to vary a state of fluid communication through the branch fluid passage.
