Which size drums on 69 Dart? And some other brake questions.

Yeah, don't be lazy- these are your brakes after all. Another $20 to make sure two tons of steel will actually stop is a good investment in my book.

I was just checking the repair receipts and the rear shoes and drums were replaced 4000 miles ago (that was 2011). If I replace the shoes 1) should I do all the other hardware, like springs, adjuster, etc.? 2) Do I need to turn the drums after so little miles?

At the times, in 2011, everything was replaced on the front, including the cylinders. I noticed the mechanic said the flexible brake tubes on the front (I guess that means between the cylinder and the hoses) were cracked and replaced. If I don't see any leaking or cracks on the flexible tubes on the rear is there any reason to replace them?

Also, any brands for the brake cylinders that are considered good quality?
