Abstract

A brake system comprises: a booster (1) controlled by a valve which actuates, by boost pressure a master cylinder (2) which supplies pressure medium to wheel brake cylinders (26, 27) via a primary brake line (11); and a boost pressure source (4, 5) which supplies pressure to the booster and to a second brake line (13) connectible to the brake cylinders (4, 5). When an anti-skid system (e.g. having solenoids 15, 16, 17) is operated a control valve within valve (12) may disconnect primary brake line (11) from the wheel cylinders and connect it to bias a proportioning or pressure limiting valve through which boost pressure from line (13) may then accordingly flow to the brake cylinders (4, 5). <IMAGE>
