Serviced brakes with 5606 from the bottom up using a borrowed pressure pot. Basically the garden sprayer method. I replaced the cap on the Vans reservoir with a barbed brass fitting and a clear vinyl tube to a 16 oz water bottle. I started out with a very light pressure and slow flow to gently push the air bubbles in front of the fluid back up to the reservoir.

Lots of bubbles at first and I thought I got all the air out of the lines because I couldn't see any more bubbles in the translucent lines, and the clear vinyl line to the catch can, but the pedals were still soft.

I did both sides a second time, but this time I pumped the pressure up and shoved it through there at a rate that filled up the 16 oz bottle in about a minute. The higher velocity carried a bunch more bubbles out that were presumably hiding in the master cylinders and the pedals firmed up nicely.

I removed the barb fitting from the reservoir which was full to the brim at this point and pulled the level down to approx 1/4" below full per the instructions from matco then installed the vented cap.

I spilled a bit of fluid on the floor so after securing everything I rolled the plane forward and put oil dry on the floor, which I'll clean up tomorrow. I also washed off the tires where they had some fluid on them with soapy water.

I didn't take any pictures because there isn't really anything complicated about bleeding the brakes, just takes some time, especially if your doing it by yourself, and its a bit messy.
