  The bound state of constituent quarks forming a $Qqq$ composite baryon is
investigated in a QCD-inspired effective light-front model. The light-front
Faddeev equations are derived and solved numerically. The masses of the spin
1/2 low-lying states of the nucleon, $\Lambda^0$, $\Lambda^+_c$ and
$\Lambda^0_b$ are found and compared to the experimental data. The data is
qualitatively described with a flavor independent effective interaction.
