I had similar thoughts about replacing just the take up reel brake pad material. In fact the pad came off while I was cleaning it and I super glued it back. I'm going to order a couple of back tension bands while they are still available. I do have a JVC back tension gauge cassette and this shows that the back tension is about right, fluctuating around 50 gcm. I understand that the correct procedure is to get the back tension pole position right first then the back tension measurement should 'come out in the wash'. There's also a 'flagging' check that can be done while observing the displayed picture with the horizontal hold offset.
