Maintenance Question for a Maintenance "Guru"

Postby IntheShade » Tue Mar 04, 2008 12:30 am

I recently converted my PA-11 from drum brakes to Cleveland disc brakes. Overall I am happy with the conversion although there is one aspect I find less than satisfactory.

I installed the brakes exactly per the STC and as a result the brake bleed valve is now below the input line which is exactly opposite to the earlier drum brakes. Since you are a Maintenance "Guru" I doubt I need explain the fallicy of this arrangement: air in the lines goes upward thus brake bleeding is not the ease of the earlier system.

What should I do to counteract this and insure the brakes are properly bled?

I guess by now you have figured out that a pressure bleeding tool is not required unless you are accomplishing the task by your self.

Don't have a pressure bleeding tool? I'll bet you do and don't know it.
1. Pump type oil can.
2, 12" to 18" of clear plastic tubing 1/8" I/D.

I'm sure you can figure out the rest. If not I'll give you a hint.

It's all done from the brake side.

Back-bleeding should fix you up Shady.
you still have to find a crew willing to fly this "barely airworthy" heap
no such thing as "barely airworthy" it's either Airworthy or Not
100% incorrect Ever hear of Ferry Permit? issued for Non airworthy aircraft
LOL

HAHAHAHA Don I have had those items for years. In fact I recently used them to shoot Marvel Mystery Oil into the cylinders of my 1969 El Camino to bust a ring free.
