New bleeders, when loosened, are a loose fit allowing a lot of air to be sucked in when under vacumn. Teflon on the threads stops this. Emptying the back reservoir should occur as it's a dual circuit braking system. The back is not accessible to drain except through the brake circuit.

I started a new post above with some weird results. Yes, I left cap loose Thanks, guys

I forgot to mention that above vehicle is 2015 Legacy.

Bled brakes while rotating tires in incorrect order and fluid was drawn from both reservoirs on MC. Result was poor braking. Bled second time at low vacumn with bleeder threads wrapped in teflon tape in correct sequence and all wheels only drew from small front reservoir. Test drove and braking was good so activated antilock a few times and bled a third time. All wheels only drew fluid from front reservoir again. How is this possible? Why won't it draw from large back reservoir also?

Kept reservoir full. One bleeder open at a time. Was sucking air around bleeders. Will try teflon tape and proper diagonal bleed sequence.

New to the forum and of course I have a problem. Legacy is 2 years old and decided to bleed brakes when doing tire rotation. Used a vacumn bleeder and when I finished I have no pedal resistance. I did not follow sequence as rotation did not match up. Never had a problem on older vehicles. Where did I screw up?
