    Just as the title says. I changed the rear calipers on my 93 hatch SI, bled them and they would stop mainly on the rears. Bled them a few more times and it still didn't change. It still is stopping mainly on the rears.
    If anyone can give me a hint as to what might be happening or what I can do I would appreciate it.

    it's probably because there was air in the rears before you swapped them out. so after the swap, you bled that air out and now the rear doesn't have that air "cushion" to delay their response. was your vehicle 4wheel disc from the factory? or were those discs swapped in? if they were swapped in, you need to get a proportioning valve off of a civic that came with 4wheel discs. it ill say 40/40 on it.

    93 hatch Si, 4 wheel disc from the factory.

    to OP:
    try not to double post.

    did you bleed the entire brake system? fronts too? did you change pads and rotors too? maybe the fronts need new pads and rotors? replacement calipers deffinatly the same part numbers as their originals?

    can you show me evidance of what you say is true?

    google, and my reading shows me
    If 4 wheel disc are standard on the USDM model, and every other countries' highest rated model (Si is to VTi is to SiR) had a higher output motor, hopefully disc brakes continued to be the standard. So I see no reason that any Si would not come with rear disc.

    The car is an SI so ya, the brakes are stock. And yes I bleed all four disk brakes several times. Im trying to rule out it being the wrong part number on the rear calipers. Iv been working on hondas for several years now and the only time I came across this kind of problem is when I swapped the rear disk brakes from a 91 Acura in 91 hatch and didn't swap over the master cylinder and brake booster. However the problem was fixed when I modified the brake booster to fit the Acura's master cylinder.

    The proportion was fine before I changed the rear calipers. Now the pedal goes all the way to the floor.

    I know the EK model has to bled in a certain pattern or you'll have air in your lines and you'll be bleeding all day.

    I don't know for sure if its the same for other models but the sequence is right rear, left front, left rear, front right

    Check master cylinder. May be leaking internally.
