Ive done a seach and have not been able to find a specific answer. I bled my brakes with a motive power bleeder and now the pedal is soft. I know the master cylinder is go (pedal will hold) so i think air may be in the abs pump. I started the procedure for cycling the abs pump that is on the Ross tech website useing the basic settings but the instructions are not that clear that come up on the screen. It says to hold the pedal down part way then release. This causes the pump to come on momentarly. The next screen says to open the FR and FL bleeder screws. I assume it does not mean both at the same time, but should this be done with someone holding the pedal down or is the system holding pressure from the abs pump? Also, can this be done in conjucntion with the power bleeder. I checked my Bentley (non cd version) and it does not give any info about bleeding the abs. I think i am on the right track with my brake problem, after cycling the pump the pedal pressure improved. Has anyone gone through this process befor?
This still leaves the question of how air got in using a power bleeder.
