Hi
so my brake pedal goes straight to the floor and I have no brakes. I've gravity bled and bled with help. I've also replaced my MC and booster. I bench bled my MC before installing and made sure I have no holes in the lines. I've bled the system at least 20 times.

 

Are you losing fluid through the calipers or rear pistons?

 

No they are all new. I've sprayed the lines with warm soapy water hoping to find air bubbles where there would be a leak, but didnt find one.

 

When you say "bled with help", what do you mean? Did someone depress the brake pedal while you opened the valve at each cylinder?

 

did you adjust the mc pushrod so it was the same length as the old ? if the pedal is going straight to the floor how is it that you are still able to bleed the brake ? is fluid freely flowing out of the lines ?

 

Sounds to me like you either installed something wrong (MC), have a defective part, or there is a massive leak still.
