A method (e.g., for monitoring a braking system of a vehicle system) includes monitoring fluid pressures of a braking system and modeled braking efforts of the braking system in a vehicle system traveling along a route, identifying one or more time periods at least one of before a brake event of the braking system or after the brake event, calculating residual forces exerted on the vehicle system during the one or more time periods, and determining at least one of an estimated braking effort of the braking system or an estimated propagation rate at which the estimated braking effort is applied by the braking system using the residual forces that are calculated.
