Urgent. BIG brake problem.
Hi I'm new Used to come on here a while ago but work took over could not remember password so I made a new anyway.
I have a NCII lane with ABS. I replaced my rear calipers today then bled the brakes pedal was nice and firm with no air in the lines. As soon as I turned the car on the pedal went really soft (like went to the floor with ease) Im thinking maybe ABS unit? I read somewere that you have to bleed the ABS unit seperatly. But I went to find how to do it. but both my workshop manaels don't say how they just refere me to another area and then that area refers me back to were I was. Im a 2nd year apprentice mechanic. so its not like I havn't bled barkes befor.
I figured this may of been a comon problem or someone on here has ran into this aswell.
If you can help I will apreciate it alot cause at the moment the car is sitting at work on the hoist.
