What is causing Left front clicking only when braking and only at slow speeds?

Hello, movement of the brake pads within the caliper brackets is possibly causing your noise. A thorough brake inspection is important, but if your technician doesn't know what to look for, they may not find anything. If it's the movement in the bracket causing the noise, some lubrication of the contact points is usually helpful. However, since brakes are a major safety area of the vehicle, definitely seek local guidance to have an inspection performed for your safety.
