After last bleeding of the brakes, we had near full  lines. Now we have air in the lines between the reservoir and the right seat  brake cylinders. Initially we found a 5606 residue on the firewall below the  reservoir. Cleaned that off and do not have it now but clear lines from the  reservoir to the right seat cylinders. At the annual in April, opened the tunnel  and cleaned the fuel filter. No seep from the brake lines was observed. My lines  have a union at the forward and a bulkhead fitting where the lines exit the  tunnel under the seats. No seep was observed there in April. The only thing not  checked in April was the bulkhead fitting to the SS braided Teflon lines to the  brake calipers and the brake calipers Whatever loss is occurring is a seep and  very slowly but we want to fix. Anyone else experience this?

I also had the leak at the firewall, had to reset the plastic fitting into the reservoir.  But I had other leaks, that accounted for some loss.   

   

Depending on how you filled the system, trapped air will accumulate over time.  Also, break wear will allow more fluid into the calipers and show some fluid usage.  

   

I am hoping to see less usage this next year with the new brake lines on the gear leg……..but I only lost about 1 oz or less last year.

I had a small seep at the firewall too once, but now with

the Bonaco lines they replace the fitting with a metal

one.  It's totally tight. Never had a leak anywhere else.

What I think happens is that the volume of the master

cylinder on the firewall is so small that when your

brakes are worn almost out, it will be empty, and your

lines above the pedals will start to show air.  With my

new lines, I won't see that anymore, but, if it's not

leaking, it won't be a problem.  I'd just dipstick the

reservoir occasionally so you can see where the level

is at.

I had  a leak in a caliper with a bad ‘O’ ring on the cylinder.  You could see the fluid on the inside of the wheel pant but to be honest it took some time to realize why I had fluid loss in the brake lines.  FWIW, with all the hate and discontent about the standard brake lines, I sure was glad to see that giant air bubble prior to actually losing brakes (not intended to start any comments, just an observation on my part   ).

Did you swap your o-rings for viton?  I've heard that's a great

thing to do with these brakes...supposedly better life and

heat resistance.  Another RV-10 buddy of mine got some for me

when he got his.

Unfortunately I hadn't heard of viton.  I put a standard replacement in and

it's been working great.  I'll look into them though, thanks.

Viton O-rings are but one option. Some folks really like

fluorosilcone O-rings. See Fluorosilicone O-Ring

http://www.csobeech.com/o-Rings.html for detail. Available from

Genuine Aircraft Hardware. Depends which characteristics are most

important. The standard mil spec aren't all that great..adequate, but

there is better.
