After work intended to address a brake pedal that slowly sinks while held, repeat the original conditions in a safe place and check whether the symptom returns. Record whether the engine is on and whether the pedal changed suddenly or gradually. Record the result before clearing codes or resetting adaptations.
Follow the maker’s procedure for drive cycles and readiness monitors. Check for visible fluid leaks from a safe standing position; do not top up without finding the cause. If the issue remains, return to the evidence instead of swapping another part.
Quick educational note
