I opted for the Beringer brake system for my RV-14A, all installed a couple of years ago.
A few weeks ago I started with the initial brake system fill and bleed.
Initial problem was it was not filling at all - short answer is that I found that I had plumbed the parking brake wrong - I had the in and out lines to the parking brake valve exchanged on both left and right lines - corrected that and rechecked and confirmed that all of line were plumbed correctly, two times to be sure.
Then I first filled and bled the the right side brake system. Fluid fill and pedal resistance came quickly - super - > then went to the left brake system.
On the left brake side > Went through the whole published Beringer fill and bleed procedure multiple times - no joy, not any pedal resistance. And no leaks anywhere.
Also, detached the bottom of the brake cylinder pistons from the left system side pedals and positioned level/horizontal to let any air in the cylinders to pass as recommended by Beringer.
Today, with assistance from a neighbor A&P, from the bottom (the brake caliper bleed screw) I pumped the bleeder to 18 PSI and in-sequence at every brake line fitting, bottom-to-top, confirmed that I had fluid flow by loosening the line fitting. - not a smidgen of pedal resistance??
And, yes - the parking brake is OFF.
What am I missing, what next? Oh, BTW I am holding my tongue to the left.
