Bill,

I's possible that the individual brake cylinders attached to the brake pedals are causing the problem. It could be any or all of the four (two on the left side/two on the right). If any cylinder is compressed even a small amount, it acts as a shut off valve for the fluid. The solution (for me) was to pull the top of each brake pedal aft as far as it will go. There's a spring on the cylinder so they should stay in position once "retracted." If you have a parking brake, that's also suspect; I'd be sure it's fully open.

For my money, adding fluid at the brake calipers is the only way to do it. This helps (but does not ensure) push air out of the lines as you fill...but even with this method, it may take several tries. This is also a two-person job; doing this alone is at the minimum bound to make a mess.

Hope this helps.

Bill H says: Need some help with bleeding the brakes.  I have replaced the nylaflow tubing in my L-IVP and  I am having a problem getting fluid back into the lines.

I originally started from the bottom  by attempting to pump fluid up thru the fitting on the brake housing.  No luck;  wouldn't take the fluid....big mess.  Next, I filled up the reservoir and tried to fill the lines from the top down;  by pumping the hydraulic cylinders on the rudder pedals.  No luck...bigger mess.  It seems like I am trying to push the fluid thru a check valve, the wrong way.

Funny thing is that I can remember years back when I first installed the brakes, I ran into the same exact problem.  Cant remember what exactly solved the problem but history seems to be repeating itself.  Guess the memory is worse than I thought.  Can there be a sequence to bleeding these brakes that I'm not aware of?

Happy Holidays, Bill Hogarty
