Abstract
An anti-skid brake control device includes a servo mechanism for controlling pressure reducing operation of the device. The servo mechanism includes a constant pressure chamber connected to an engine intake manifold, a variable pressure chamber alternately connected to atmospheric pressure and vacuum in the engine intake manifold, and a vacuum pressure responsive valve including a flow restriction passage wherein, when the engine vacuum rises above a predetermined level due to engine brake operation, the restriction passage is actuated to restrict the vacuum flow to the variable pressure chamber to gradually carry out the pressure recovering operation of the anti-skid brake applied with the engine brake operation.
