New methods and devices are described that are aimed at preventing the outbreak of fire in a hydraulic rotor brake. These methods and devices can be used in the rotor brake of a helicopter and comprise a first and second seal, with a drain groove positioned in between these two seals to drain leaked fluid away from the hot parts of the brake. In the brakes described, the second seal is positioned closer to the heat sink of the brake than the first seal. The drain groove is also connected via a channel or channels to a drain outlet or outlets.
