I'm at my wits end. I installed the Ford Racing Brembo 4-piston brake upgrade kit that my wife got me for Christmas.
I followed the (marginal) directions to a T, not like it's complicated anyway. I did only one side at a time so as not to open the brake system a lot at one time. At first, I did not install the rear stainless lines that came in the kit, I only swapped the front stuff. After installation, I bled the brakes using a mighty vac hand bleeder kit (I was by myself). The reservoir never got even close to being low. After spending 1.5 hours bleeding, I never could get any pedal firmness and the car didn't stop worth a damn.
Next day, I enlisted my wife to help me bleed them in the normal way. Apply pedal pressure, crack bleeder, close bleeder, release pedal, etc. After seeing no air bubbles coming through the line and nice solid fluid coming out, we called it good. Still not pedal firmness and car still won't stop.
I let the car sit for a week at this point. Then, my brother and I went ahead and changed the rear lines out to the stainless ones. So, once we were done with this we proceeded to bleed all four corners. Starting with passenger side rear, then to driver side rear, then passenger side front, then driver side front. No bubbles, solid fluid from all six bleeders. Same result, no pedal firmness and the car won't stop.
Next day, removed Brembo calipers and shook them, tapped them with a rubber mallet. I didn't remove the lines so as not to open the system again. Re-bled the front calipers, no bubbles, nice solid fluid. No change in pedal firmness and the car won't stop.
I've bled the Brembo calipers using both methods, inner bleeder first then outer and outer bleeder first then inner.
I'm out of ideas. I don't see how air could have gotten into the master cylinder. The reservoir never got close to being low. I've gone through two quarts of DOT4 brake fluid. I can't get any more air out of the system.
When bleeding and the car is not running, the pedal gets firm AF. As soon as you start the engine, the pedal gets spongy as hell.
I've now reinstalled the stock brakes, bled, same result. Can't get any decent braking force.
It's been mentioned that air could have gotten into the ABS module. HOW THE FUCK? I can't find anyone else that's had this much trouble.
Help. I'm about to set the car on fire.
