Your nails are too clean Steve.

You can just loosen the 1/4” bolts holding the backplates a couple turns, pump the brake, fill the master, tighten the bolts back up, and have the same effect as adding fluid after locking the parking brake- what I do when there’s no parking brakes and I need to preload them a bit... This has worked well on a customer’s J-5 with stock diaphragms and double pucks with 31’s- enough to hold at full power with the o-290d without mashing the pedals too hard...
LOL, start of the day and my left hand. Back when I was attempting to go to college but spending too much time working on cars my Dad suggested A&P school. He said it would be a cleaner living than working on cars. He was right. Good hand cleaner helps as well.
I have a Masters Degree and a PHd in Fighter Pilot and get my hands dirty most every day!
So “hypothetically “ what high pressure system would you recommend for a cub that is in service and that has the under seat battery conversion?
Parking brake valves and high pressure hoses already installed.
Ease of installation, and having “few” operational concerns desired. (Hypothetically speaking of course)
...Filling from the bottom works great for bleeding, but after the brakes are bled I just fill them from the top. It's easier and not as messy.
I top off the brake on my C180 from the bottom up --
for me, it's quicker & easier than crawling under the panel and fumbling around.
What I don't like about filling from the bottom is that you have to be pretty careful not to squirt some air into the system and make things worse.
Don't you still have to get under the panel to take the plugs out of the master cylinders?
The vent plug is a straight thread not a pipe thread

I have stock Scott diaphrams and Bodell wheels/brakes on my PA-12. The combination is "good" with 8.50's, "adequate" with 26" Bushwheels, and a bit marginal with 31's.
I don't have any advice that might be considered sophisticated, but - - I've owned this plane for more than 45 years, and have changed diaphragms twice. Once because one ruptured on a short gravel bar. That was entertaining! Seems to me that they're good until they're not? Some of the mechanics here will have better, more detailed information for you.Hi Gordon,I see you have the original Scott brakes fitted.Can you offer any advice re changing diaphragms,and longevity of such.Thanks if you can help.
