Abstract

A parking brake assembly for an electronically controllable pneumatic braking system for a vehicle includes a parking brake unit having a supply connection to receive a supply pressure, a brake request connection to receive a parking brake request, and a parking brake pressure connection to provide a parking brake pressure. The parking brake assembly further includes a first ABS valve unit for a first channel and a second ABS valve unit for a second channel. The first ABS valve unit is configured to provide a pressure for a first spring-loaded brake cylinder at the first channel and to admit air to the first channel, in stages. The second ABS valve unit is configured to provide a second brake pressure for at least one second spring-loaded brake cylinder at the second channel and to admit air to the second channel, in stages.
