  "textContent": "A control method for controlling a spring loaded brake actuator () comprising a first chamber (Ch) to receive a parking brake pressure (PBR) acting against a main spring (), and a second chamber (Ch) to receive a service brake pressure (SB) for applying a service brake force, the method comprising a circumstantial selection of one control law among a set of control laws comprising two or more compound control laws:—where the first compound control law (CL), known as anti-compound mode, is such the service brake pressure (SB) is electronically controlled such that the resulting total braking force (F) does not exceed a first upper limit (UL) corresponding to the force of the main spring () when the parking brake pressure (PBR) is substantially null, —where the second compound control law (CL), known as controlled-compound mode, is such that the service brake pressure (SB) is electronically controlled such that the resulting total braking force (F) does not exceed a second upper limit (UL) higher than the first upper limit.",
