Finished the rear disc swap in my 96 Si w/ABS
I let the system run dry and now I can't seem to get the pedal back to normal.
It's low and sinking when the car is running. Feels okay when the car is off.

I've read many posts saying it's the MC. Tried a new re-man MC unit. Still the same. Tried another MC, still the same. Tried another prop valve and for the most part the sinking is gone...

I shouldn't have to bleed the ABS unit??

BTW the MC is a 15/16 and I also tried a re-man 1" unit too.
Should I have to adjust the pushrod?

 

you have to bleed the entire system.. abs unit included

otherwise your brakes will suck

 

Make that bitch BLEED. soft pedal with car on is classic sign of air-in-line.

 

I bled the whole system like 5 times and no air.
I guess you need a special tool to bleed the abs unit?
I have the ABS diagram and tried manually activating the solenoids but no luck. I hear the them clicking. But a low pedal still.

 

Bleed it more. Buy a big bottle and make a point to go through the WHOLE bottle.

 

did you bench bleed the MC before you installed it?

 

Yes I did.
NO air the MC.

I'm guessing all my probs are b/c I let the system go dry?
I'll try bleeding like the end of world tonight and let you know what happens.
