    Relay-like clicking noise when applying brakes

    Hi all, recently I'm hearing an electronic clicking sound like a relay coming from under the dashboard when applying the brakes at low speed. For example while I'm in traffic and stop and go I always hear the click when pushing the brakes about half way down. Any ideas why this is happening?
