In $\triangle ABC$, the sides opposite to angles $A$, $B$, $C$ are $a$, $b$, $c$ respectively. It is known that $\frac{\cos A - 2\cos C}{\cos B} = \frac{2c - a}{b}$.

(1) Find the value of $\frac{\sin C}{\sin A}$;

(2) If $\cos B = \frac{1}{4}, b = 2$, find the area of $\triangle ABC$, denoted as $S_{\triangle ABC}$.
