Seems a little steep.
Rear disk brake pads take 15 min/side, in my driveway using car jack and hand tools. No rotor turning/replacement included.
Handbrake cable requies hoisting, heat shield removal, perhaps lower exhaust as well as re & re console, should be 2hrs for pro.
If labor includes turning rotors 4 hrs would be high but not excessive.
I would get estimate elsewhere if you are unable to do it yourself.
