bled system as per, but got NO pedal

Handbrake OFF engine OFF, but if you dont replace hydraulic parts, you should NOT bleed brakes! Loosen master cap syphon any extra fluid out, and push back the piston. On the rear, does it have the screw in piston? You may have the tab of the piston or pads in the wrong spot. From Honda Service News   On all Honda models, if you're manually bleeding the brakes, make sure whoever's pumping the brake pedal pushes it only halfway to the floor. If the pedal is pushed all the way to the floor, you run the risk of driving the master cylinder secondary piston into any sediment or deposits that may have collected on the piston cylinder walls. If this happens, the piston seals can get permanently damaged and cause a leak. You can also avoid this problem entirely by using pressure bleeding equipment.

Here is a video and guide below to help you bleed the brake system correctly. https://youtu.be/w7gUsj2us0U and https://www.2carpros.com/articles/how-to-bleed-or-flush-a-car-brake-system and https://youtu.be/WDxvEQrMkBg Please run down these guides and report back.

Thanks for the response Merlin ... Yeah, the piston type is a 'screw' in ... That's what caused me the problem, have only ever encountered the 'push-in' type (20 years since I was an active mechanic) ... pads where down to their last on O/S/R, piston all the way out, so I assumed it had seized when it wouldn't push back in ... remove bleed nipple to clean, plus flexi pipe, then realized my error (fluid res' went from max to min).

Bled until I got constant fluid ... only bled the rear two, engine running, H/Brake off ... I've got brakes, but feels like front only. Back when I was a 'Mech' I remember having to re-set the h/brake slack adjuster on certain cars ... h/brake feels same as before though.

Did the N/S/R no problem, minimal fluid loss ... Maybe try a complete bleed on O/S/R first ... then do a simultaneous bleed on all four ??? What do you think ???

Thanks in advance ... Chris.

You may have to bleed all 4 wheels, this is a diagonal braking sytem, meaning the left front and right rear are paired of the master, so if air got into the rear line, it probably got into the fronts. Remeber, bleed with engine off and only push 1/2 way down on the pedal to bleed! On Civic, sequence is RR, FL, RL and FR.
