Recommended Next Step
Stop Driving
Urgency: Treat this as a priority. If braking distance changes, the pedal feels wrong, or the noise is severe, avoid driving until inspected.
Treat this as a braking safety issue until a brake inspection confirms the vehicle can stop normally.
Symptom context
Since this comes and goes, intermittent wiring, sensor, heat-related, or connection issues may need to be checked.
Next step
Inspect pad thickness, rotor condition, caliper movement, backing plates, and wheel-area debris before replacing parts.
