I just finished installing LS1 brakes on my Z. I bled the brakes (RR, LR, RF, LF) but the pedal falls to the floor when the car is on.

This is my first time bleeding brakes, so I'm sure I screwed something up...any ideas?

 

Are the lines hooked up correctly? try bleeding them again?

Also, im gonna do this next week, did u use a install guide online at all? IF so which one?

 

did you bleed the ABS unit?

you have air in the lines somewhere, bleed the ABS unit using the two nuts on the front of the unit.

when my ABS unit bled dry and got air in it, the damn pedal would fly to the floor every time the ABS kicked on. i just re-bled it every time and eventually all the air got out.

 

I found two sites. The first one was the most helpful

I didn't bleed the ABS. I'll have to check that in the morning. Where is the ABS unit?

Also, my pass. side ball joint was rotating when I put the castle nut back on. How bad is this?

 

right side of the engine bay(looking at it from front) its in front of the master cylinder
its easy to recognize, just a grayish silver square unit with metal brake lines coming off it

 

OK, I found it and tried to bleed it. No luck. I only found one bleed screw on it (the back side of the box, it used a 19mm wrench). I thought there were 2 of them. Maybe b/c I have a 93 it's different?

Any advise on the ball joint?
