Well I noticed something recently. When at a traffic light on a rainy day with wipers on, I feel movement in the brakes when the wipers turn. I'm not complaining, but I was just wondering if that was normal. I can feel the wipers moving with my foot. It effects nothing, but still has me curious nonetheless. Anyone else?

 

It has been noticed before- there is a thread in this section entitled " brake pedal throbs"

I'd post a link but can't figure out how to do it from here
