The manual explicitly states that water on the brake discs increases response time and explains that brake pad contact with the disc surface removes the water film. ^[1]

Distinguish temporary water film on the discs from persistent braking abnormalities; have a qualified technician check the discs and pads. ^[1]

Stop using the vehicle and have it inspected and repaired if the abnormality persists; do not directly replace calipers or electronic control assemblies based on wet-road symptoms alone. ^[1]
