ABS Hydraulic Modulator Types & Components 

I am fascinated by technology .. I was a Donnington GT championship outright champion in 1980. My self made Championship winning car had twin master cylinders to allow for BALANCED braking . As the driver, I was the ABS modulator . A recent brake pad and fluid flush on my newly acquired 2008 Citroen C5 saloon car . Resulted in a pedal going to the floor whenever the engine was started . Otherwise the pedal was a good firm TOP pedal .I was convinced that this sinking pedal was possibly worn Master cylinder seals , failing under the extra pressure from the Brake booster . After flex honing the brake master cylinder and replacing the seals .€6 euros . The sinking pedal still existed . I bought a Foxwell NT630 Plus abs scan / bleeding scanner .EXCELLENT. this scanner allowed me to cycle the ABS module and resulted in a marked improvement . Still not 100% to my liking . The Foxwell NT 630 Plus scan tool displays the operation of all four wheel speed sensors . Showing they were all functioning with no faults . I have made a couple of test drives involving a few firm brake applications to bed in the new all around brake pads . The pedal is now starting to show some marked improvement in response . and the dreaded Sinking brake pedal to the floor has seemingly sorted itself out . This has left me wondering what the ABS module could have operated to introduce the sinking pedal . Throughout my long life of driving I have never had any issues with maintaining my own vehicles braking systems . Would Vacuum brake bleeding have upset the functions / operation of the ABS module / solenoid valves etc . I made a super Vacuum bleeding arrangement which functions really well . Unfortunately My Foxwell NT630 Plus abs scan tool does not show the functions / operations of the ABS module . It would be nice if the various operations could be shown visually on the scanner display screen . This would allow the operator to diagnose a sticky / faulty abs solenoid / valve . The scanner displays LISTEN.
