We discuss the Hamilton-Jacobi formalism for brane gravity described by the Regge-Teitelboim model, in higher co-dimension. Being originally a second-order in derivatives singular theory, we analyzed its constraint structure by identifying the complete set of Hamilton-Jacobi equations, under the Carathéodory's equivalent Lagrangians method, which goes hand by hand with the study of the integrability for this type of gravity. Besides, we calculate the characteristic equations including the one that satisfy the Hamilton principal function S. We find the presence of involutive and non-involutive constraints so that by properly defining a generalized bracket, the non-involutive constraints that originally arise in our framework, are removed while the set of parameters related to the time evolution and the gauge transformations, are identified. A detailed comparison with a recent Ostrogradsky-Hamilton approach for constrained systems, developed for this brane gravity, is also made. Some remarks on the gauge symmetries behind this theory are commented upon.
