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? |

Do you have cleveland brakes? Has your IA checked, and / or replaced ALL of the hoses? The big one, that is always overlooked is the short one, from the hard line to the caliper. It has a hard outer shell, but it can leak, or suck air as it hardens, and gets old. S2178-4-0057A Fig 46 item 23 (I think it crosses to another number) It takes alot of abuse being where it is. I changed out my calipers a few years back, and I think I got the 30-69B with pins, and of course the AN fittings. The calipers are "one size", and for left or right, you just put the AN fittings on the "up or down" side. The pins are are just driven in, with a mallot and a block of wood, (measure for the depth) As for the different numbers, (30-61D, or the 30-69B), I am going to have to do more research.

Cleveland has a component mx manual, AWBCMM0001
Section 101 has a troubleshooting table. Get it here. https://www.parker.com/literature/Ai...AWBCMM0001.pdf It is cleveland specific, but good info for all brake systems. I am still looking for specific numbers, if you do NOT have cleveland brakes. If you do NOT, please send your aircraft S/N so I can look it up specifically. Regards, Randy |
