Sumario:We are concerned with the existence of extremal solutions to a large class of first–order functional differential problems under weak regularity assumptions. Our technique involves multivalued analysis and the method of lower and upper solutions in order to obtain a new existence result to a scalar Cauchy problem. As a consequence of this result and a monotone iterative method for discontinuous operators, we derive our main existence result which is illustrated by several examples concerning well–known models: a generalized logistic equation or second–order problems in the presence of dry friction.
