Swapped to braided brake lines and ended up with a spongy pedal for 3 days
Finally got around to putting stainless braided lines on my 2008 Civic Si last weekend. Watched like four different videos, bench bled everything twice, used a pressure bleeder I borrowed from a buddy. Still got air somewhere. Pedal went almost to the floor on the first test drive. Turns out the rear caliper banjo bolt was the issue, the washer was on backwards the whole time. My fault for rushing. Swapped it and did a full manual bleed again, took like 2 hours but it's solid now. Anyone else run into weird bleeding problems after a line upgrade? Think I should just get speed bleeders for the next time.

Man that banjo washer thing is such a classic mistake. Did the same thing on my old WRX years ago and chased my tail for a whole weekend. What finally helped me was doing the two person bleed with a clear hose on the bleeder screw so I could actually see the bubbles stop. Also found that cracking the banjo bolt just a tiny bit while someone presses the pedal helps push trapped air out from behind the washer. Another thing that saved me was zip tying the pedal to the floor overnight, that forces any tiny remaining air bubbles up to the master cylinder. Speed bleeders are honestly worth it just to save your back from all that crouching and yelling back and forth.
