We describe a Monte Carlo code that simulates the evolution of angular momentum of pre-main-sequence stars in the context of the disk-braking paradigm. The code is similar to that presented by Rebull et al. (2004), but includes several improvements. The code allows us to set parameters such as the distributions of masses, ages, and disk dissipation timescales, all of which are constrained by observations. Also, we use the evolution of stellar radii predicted by theoretical tracks to evolve the periods of disk-less, unregulated stars and to calculate the amount of angular momentum drained as a function of time from stars regulated by disks. We present quantitative comparisons between models and recent observations of young stellar clusters in order to constrain disk-braking parameters.
