Roger i was under the impression that the passage from the front master to the calipers is always open unless the abs is operating due to altering wheel speed, just wondering if the front brake is now working as expected with the ignition switched off?
As far as i understand the brake switch on the lever is also part of the abs cycle in combo with the wheel sensors, maybe an abs valve was left in the wrong state ( sticking) when the engine was last switched off........
How long ago has the fluid been changed and what did the old fluid look like when replaced?
There is likely still some old fluid inside the abs module, unless it actuates multiple times it just sits there and gets old.
If it was me i would find a grassy area and operate the abs system ( handle vibrates ) multiple times until you feel it is reliable, interesting and if my memory serves me correctly ( rare these days ) there was another member with a similar brake malfunction, he or someone might chime in here, we could not understand why it happened but your case shows that it did, very interesting.
