Hello there.
I just put new brake pads, new rubber on piston calipers and new repairing kit for master cylinder on my ZX-14 2010 ABS. I have also steel wires.
After bleeding the lever (many times including master cylinder) its too soft .After 2 presses its harder. After few seconds rest when I am pressing again its the same story. Its not so soft like its no brakes but its 1 inch difference between first press and second press. I heard that sometimes it need to connect computer switch on the abs pump to work continuous and then try to bleed.
I would like to buy computer for kawasaki and would like to try make myself. Can you recomned me what i need to buy??
Maybe there is something on aliexpres? I am from europe.

lolololol bots aren't so smart after all... (and neither is AI which is basically a bot)

No need to buy any computer. Break the banjo bolt, press the lever to the grip, but tighten the banjo before the lever hits the grip. If you have a few pumps and the lever goes hard, it's at the master's banjo bolt to steel brake lines.

ABS does not need a bleed. That's only when it's installed first time. This is not an open and close nipple action. Keep the nipple open and keep pumping. Close one time is the trick.

I know how to doo that. As I said i made it properly few times and still without result as i want.
I heard about simillar issues from my friends and they made it with abs pump working continuos throuhg the computer.
Maybe when i was instaliing new steel wires sth happened and in fuel pump is air? I dont know.

No. Because in the ABS case, there are more like solenoids opening and closing, so flow would be just another flow channel as if its a long hose.

See if you can see bubbles come up from the master? Remember it may have a splash pan over the hole, or if not, it will squirt straight up and pepper the paint so there is the caution looking for bubbles.
1. Press on the lever till you fart, or crack a tooth, meaning pretty hard.
2. Release. See any bubbles show up, on the way up?
3. Say it's yes. Then without touching the lever, meaning less than a mm of a move, did bubbles rise?
4. Say it's yes. Well, you'll be there all day just tapping that lever until the bubbles no loner rise, that's another trick if, pump till arm pump, banjo bolt show no joy.

But from where I'm standing, it's the Charlie way to clear the bubbles away.

I changed master cylinder for Brembo RCS19 and still the same problem like before .
There is no bubbles from master cylinder and calipers at all. I Bleed as service manual says and still is the same problem... Any ideas??

The trick to is to keep the caliper bleeder open, pump till you have arm pump, and just add fluid when the level drops in the rez. If you are opening and closing with every stroke, that's more damage to the taper of the nipple to caliper, caliper being the softer side.

Brembo master has the nipple bleed instead of breaking the banjo bolt if not there. The bleeding hose line out of the caliper's nipple should have a U hoop high enough on the caliper side of the hoop so when you stop pumping to fill the rez, any fluid in the line will suck that high U's fluid back in.

So bottom line you never close and open to bleed with every pull of the lever to the grip. With the master's nipple though, it's opened once, pull lever and close before the lever reaches the grip. Then pump with all the nipples closed and feel for a tight lever.
