  Research on black holes and their physical proprieties has been active on
last 90 years. With the appearance of the String Theory and the Braneworld
models as alternative descriptions of our Universe, the interest on black
holes, in these context, increased. In this work we studied black holes in
Braneworld models. A class of spherically symmetric black holes is investigaded
as well its stability under general perturbations. Thermodynamic proprieties
and quasi-normal modes are discussed. The black holes studied are the SM (zero
mass) and CFM solutions, obtained by Casadio {\it et al.} and Bronnikov {\it et
al.}. The geometry of bulk is unknown. However the Campbell-Magaard Theorem
guarantees the existence of a 5-dimensional solution in the bulk whose
projection on the brane is the class of black holes considered. They are stable
under scalar perturbations. Quasi-normal modes were observed in both models.
The tail behavior of the perturbations is the same. The entropy upper bound of
a body absorved by the black holes studied was calculated. This limit turned
out to be independent of the black hole parameters.
