Can your brake pedal go almost to the floor with engine running?
I've recently done my brake job and started noticing the brake pedal can be pushed almost to the floor(stops at 1'' to 1.5'' above the floor) under steady hard force with engine running and gear in P.
It's not a sinking feeling. I had to really stand on it to make it go that low. Pumping the brake when engine is off makes the pedal rock hard. I mean brake feels okay during driving. Is this normal? Does anyone experience the same? Perhaps the pedal did the same before, but I have never checked. Every little thing can easily get me paranoid after brake change |

Caveat....I have not bled brakes in 45 years. So the response is based on some general knowledge that will hopefully led you in the right direction. I maybe totally correct or totally wrong or somewhere in between!
First if your brakes were bled three times, they were bled improperly or you have something wrong. The first time should have been enough. When you say "Power Bled". Does that mean they hooked a positive pressure system so the job could be done by one person rather than two? In speaking with my local indy mechanic he uses a computer to open and close the ABS gates when bleeding. I'm kinda thinking that did't happen with your bleeding. Here's why. I believe that ABS is actuated under fast hard braking, not slow steady braking. So when your driving and they feel more normal the ABS is probably kicking in, but in the driveway under slow steady pedal pressure it's not kicking end. To fix this, a proper brake would do it. Again I basing my thoughts on the typewriter, vinyl record and rotary phone era. I could be full of it! |

Some experience will just always be true. Thanks for sharing.
I did not bleed ABS. Maybe I should. My Indi told me if there is any air, it will be pumped by ABS out of system to master cylinder and eventually bubbling out. On Saturday, I used wood block against the seat to depress the pedal and left it overnight. It gets a little better now. I consulted mechanic from another shop and they said it's normal with all X model, even X5. Not sure if this is indeed the case. I never really pressed the pedal all the way down before the brake change. Are you able to depress the pedal to 1-2 inches above floor on your X3? |
