nbml430,

Pedal was fine before the
motive power bleeding. I used the motive unit successfully last year when I replaced the rear calipers, rotors & pads. I am sure something odd occurred during my front end brake job last weekend....just trying to get to the bottom of it.

Schumi,

I am beginning to think that is what
happened....just not sure yet how it
occurred yet...but you are right I will
probably re-bleed the brakes next weekend to see if I can flush this
air out.

Benz300,


Good articles! Thanks for the pointers.
I think between these articles & the
advice posted in this thread bleeding
all 4 calipers again is the only logical next step. I just think I will utilize the motive unit again and if that still does not do the trick then revert to the two person method.

And yes, I will definitely update as I go along.

Two additional questions: what is the maximum pressure can I pump the MB W124 brake system up to i.e. the motive unit maxes out at 30psi?

Is 25 psi pressure that I used too low?
