Drum inside disc is the best rear brake design out there IMHO, and as long as the system gets some periodic maintenance its virtually trouble free.
All the cars we own have this type, our LC also the Forester and our 24 year old Merc, almost every well designed car of recent years had this design of rear brakes until some brainbox came up with wallet emptying electric parking brakes, something else no one ever asked for but has pandered to those incapable of controlling their vehicles on hills so more and more new cars are being designed with the junk.
The beauty about DiD system is that the rear calipers can be simple affairs, and the best type too, opposed pistons, not single piston sliding calipers which invariably give seizing troubles sometimes down the line, self adjusting calipers where the parking brake operates the rear pads almost always give trouble eventually and are expensive.
Every other year, every year if you have the time, remove pads clean inspect and lube up the moving parts with the correct brake grease (not coppaslip which attacks rubber), not forgetting to exercise the pistons in their bores, which couldn't be easier with opposed pistons as you push one in the other slides out, plus the odd brake fluid renewal, then a coat of paint once in a while and our brake calipers can and will last forever.
The trouble with those self adjusting calipers that operate the parking brake too is its difficult to exercise the pistons in their bores to the same extent so they inevitably have seizure issues.
