The debate between cable and hydraulic brakes will go on for years like clones, bling and alleged engine tuners.
In general,
Cable brakes
pros,
good if you've got a decent servo to pull them on and you can install them correctly and make them work evenly.
Cons,
not as powerful imo as hydraulics, the cable stretch and you loose performance.
Hydraulic brakes
pros,
Once installed and combined with a good servo, nothing will stop your car better, - ok maybe a telegraph pole. They are/should be fit and forget
Cons,
They can leak although I've never had any issues with any I've used but if you burst a pipe or snap a union then thats it, you've no brakes - this is why you should never use front and rear hydraulics off one master cylinder.
