A function $f(x) = a \cos ωx + b \sin ωx (ω > 0)$ has a minimum positive period of $\frac{π}{2}$. The function reaches its maximum value of $4$ at $x = \frac{π}{6}$.

1. Find the values of $a$, $b$, and $ω$.
2. If $\frac{π}{4} < x < \frac{3π}{4}$ and $f(x + \frac{π}{6}) = \frac{4}{3}$, find the value of $f(\frac{x}{2} + \frac{π}{6})$.
