The hand brake does not use the compensator, so the handbrake fault is a separate issue to a low braking efficiency percentage.
Have they actually pointed to the compensator? The usual issue is the top of the compensator acts as a water trap and corrodes the four brake pipes in/out of the compensator. Some come away in your hand when you try to undo them. The compensator takes brake pressure away from the rear callipers during the latter stages of braking as the weight is transferred onto the front axle, this means there is more pressure at the rear to begin with (until the compensator kicks in), so I doubt the fault is the compensator, if you follow.
I would check out the condition of the pipes (incl flexi hoses at the calliper) as well as working out when it last had a brake fluid change assuming your discs and pads are ok.
The handbrake will need adjusting; loads of threads on here for that one.
