Good afternoon all,
I am have an issue with the rear bailing ring on the P30 Master Cylinder Cover. When I attempt to push the bailing ring rearward to open the cover it is prevented from going back, due to its striking the vacuum booster.
Has anyone had this issue and if so how did you over come this situation?
Thanks in advance,
Tom K.

Bruce,
Good to know that others have the same issue and I didn't do something wrong. It appears that I may have to adopt your method as well. I appears that a small funnel and hose need to be kept onboard for top offs.
The six wheel disc brakes appear to be working well as well. I will know when I get the unit back on the ground.
Thank you for the tip.
Take care,
Tom K.

Same here, pop one of the legs out to remove, then pull it back into place with a pair of channel pliers. I use a turkey baster with a piece of clear tubing stuck in the end to top up the reservoirs.

I fill my P30 with a laboratory wash bottle. Search the internet, Amazon has rather a lot.
I also use one to top off batteries.
A potential down side is they are somewhat subject to drips from changes in atmospheric pressure. I minimize that by removing the spout and letting it drain before storage.

If you have to frequently top off any master cylinder, you have problems
elsewhere that nee attention. Like worn brake pads and/or shoes, bad hoses,
or leaks in the brake system somewhere. That is a closed and sealed system.
Fluid cannot just disappear without a fault someplace. Keep looking. Your
solution is out there.

Thank you all for the great responses! Russ I forgot about the Lab Wash bottles.
I do use Harbor Freight bottles with a 180 degree curved tube and the adjustable tip for the brakes on my aircraft. I un-screw the bottle lids because I learned about the ramifications of atmospheric pressure while cleaning up my aircraft supply cabinet. LOL.
Both the baster and wash bottles are great ideas.
Jim, I hope not to be filling my reservoir and more of checking. After losing my brakes in my old coach, I will forever have a heightened awareness of brakes and brake system checks.
Thank you guys for all your insight and thoughts.
Take care and have a great weekend,
Tom K.
