sould be easy like,the speed sensor on the wheel hub was unplugged. ..... go to Autozone and asked for them to use their ********ABS code reader, (also free of charge but different from their DTC code reader).

Something to check, if the master cylinder is over full, full to the top of where the cap goes on, it would do this. There should be a full level mark on the side of the reservoir.

The cap has the rubber piece under it, so it takes up the air void, brake fluid expands when it gets warmed up, so it starts to apply brake pressure.
