Abstract

Disclosed is a method for controlling brakes in a trailer vehicle comprising a pneumatic brake system, service brakes and an electronic brake system with anti-lock control, wherein at least one axle of the trailer vehicle is fitted with spring-loaded brakes and revolution rate sensors. The method comprises: monitoring with the electronic brake system whether there is a braking demand, monitoring with the electronic brake system whether at least one wheel of at least one axle is locking up, and if there is no braking demand and at least one wheel of the at least one axle is locked while traveling, controlling the pneumatic braking system with the electronic brake system to pressurize the spring-loaded brakes and to brake the trailer vehicle by the service brakes automatically and with anti-lock control. A valve arrangement is also disclosed.
