Mushy brakes

[YankeeClipper]

Based on some of the helpful feedback you all have been giving, my IA has decided to go ahead and replace at least one of the brake cylinders. I'm not sure this is really where I'm taking on air but they are fairly old and it's worth a shot. They were of course repacked with new bits recently, but he wonders if, as one of you have pointed out, it's not leaking out past the seals.

So in my search for this I've noticed that Cessna part numbers are different from left hand and right hand, yet the Cleveland part number for my Delta model shows only one part number: 30 - 61D. Then, confusing matters all the more for me, the Cessna part catalog doesn't really specify different brakes for different years, at least not for 65 through 71. But Cleveland does. Can I use the 30-69B that they specify for the echo models, even though mine is a delta?
