Squishy Pedal After Stainless Lines

[lava5oh]

I installed Stoptech stainless steel front brake lines today, bled the brakes, tightened everything down and have a squishy pedal while the car is running. While the car is off, it is able to build pressure normally, it's only squishy when the car is running.

I checked all lines for leaks, made sure everything was tight, and everything checks out. I bled the brakes again, and am now stuck not knowing what the problem is.

Any help would be appreciated!

How badly did the brakes bleed..? You might have a vacuum leak, taking in air..?

Vacuum leak was the only thing I was thinking. Nothing was wrong prior to changing the lines though. That's all I changed.

Try bleeding the brakes again, starting furthest from MC and working your way back. It sounds like you have air in the system.

Are you using a 1-man bleeder setup, or doing it the old school way?

I am happy to report that I'm an idiot. First time ever having 4 piston calipers... I never drained the other side of the front calipers. That solved the problem. Thank you all!

For the first time especially, follow this bleed sequence: Inside fitting. Outside fitting. Inside fitting again.

Definitely air in the lines!

Did you use a pressure bleeder similiar to the Motive power bleeder? Makes bleeding the brakes MUCH cleaner, easier, and faster.

Curious, does the clutch slave share the same fluid and reservoir as the brakes?

I did not use a power bleeder, old fashioned tube and bottle haha!

Yeah, the clutch shares the same reservoir as the brakes.

I presume you bleed the clutch as well?
