W203 Sports Coupe brake pedal vibrates slightly when wipers go on?!!?

[coolpot]

I struggle to see how they are linked? but if my windscreen wipers are on, ive noticed my brakepedal kinda makes a weird vibration, if i was blindfolded i could tell you exactly when the wipers came on and went off again!!


any ideaS?

This one is new to me. The wiper motor is located on the bulkhead or firewall as the americans say and so is your brake master cylinder and servo unit. So its possible that the wiper motor is vibrating for some reason and the resonance is sent along to the brake pedal. I would start by examining the wiper motor itself. Also the motor and wiper arm fittings, f or vibration.

mine does exactly the same thing, maybe it's a "feature"
