Brakes and Cowl

Finally getting back in the swing of things after taking a break over Christmas. 

Brakes: After some more adjustments, we no longer have brake fluid leaking from any of the fittings, but are having issues bleeding the brakes.  The right brake has air infiltrating into the lines somewhere around the passenger-side cylinder. Also, the left brake was bled but over time has gradually been getting some air bubbles in the lines near the left master cylinder.  After attempting several times to bleed them without success, we suspect some of the internal brake cylinder seals are leaking, and perhaps sitting on the shelf for 8+ years before installation didn't help.  We bought Matco brake rebuild kits and plan to replace all the seals on the brakes before bleeding the brakes again.

Cowl: With the prop installed on the airplane, we are not happy with the aesthetics of how the front of the cowl lines up with the spinner.  Because of this, we're going to do some fiberglass cowl modifications to make this look better.  It may reduce drag a bit too, but probably not much.

We are gluing some styrofoam to the front of the cowl which we will later shape and use as a form for laying up the fiberglass.  Hours: 10
