I've noticed this same issue when the pedals aren't return= ing all the way, pull the tops of the pedals toward you and the fluid shoul= d flow from the brakes up to the reservoir.

This is just for anyone= out there that hasn't done this before or isn't having luck with t= heir brake bleeding method-

You can use the bleeder available from AC Spruce or make you own from a= garden sprayer by installing a line with a small ball valve on it and from= there a piece of red Tygon to attach to the caliper.=A0 It takes two peopl= e since one needs to man the bleeder and valve and the other operates the p= edals. If your Lancair is plumbed per the manual then start on the co-pilot= side, get it really good and then move on to the pilots side. Doing the le= ft or right first does not matter.

Here is our process:
1) Make sure there is plenty of fluid and good = pressure in the bleeder tank and no air in the line coming from it, you don= 't need to introduce more air into the system.
2) Be prepared for ov= erflow from the reservoir.
3) Attach the line to the fitting on the bottom of the caliper of the side = you wish to do first but do not open the fitting yet.
4) Verify all peda= ls are pulled back at their tops.
5) Open the valve on the bleeder and t= hen open the fitting on the caliper with a 1/4" wrench by loosening it= about a half a turn.
6) Have someone push down on the brake pedal very slowly and then le= t the pedal up even slower. Verify the pedal has fully returned.
7) Clos= e the fitting on the caliper and try to pump up the brakes on that side. 8) Repeat steps 5, 6 and 7 until brakes feel very hard.
9) Close the fit= ting on the caliper first then close the valve on the bleeder tank before r= emoving line from the caliper.
10) Switch over to the pilot's seat a= nd repeat steps 4-9, this should complete this side of the brake system.
