Tapping Noise in Brake Pedal Cold Start

[kenm09]

Ok, so it doesn't seem that big of a deal, but it's getting annoying. At a cold start, there is a tapping noise/vibration in the brake pedal for about 30seconds-1 minute. Any thoughts to what is going on?

Have you read any of the V8 Manifold tick threads? Perhaps look at some clips on youtube to see if it's the same noise.

I have a v-6 and have the same thing. More of a vibration in the brake pedal than a noise. I think it is the solenoids on the brakes doing system checks or something. Just an idea.

I have the same thing. I don't feel it as much as hear it.
