The title sums it up. When my wipers cycle I feel it in the brake peddle if I happen to be braking at the time of the wipers making a pass across the windshield. I realize they're not on the same circuit so what could cause this? When I mentioned it to my service guy he had no idea how that would even be possible. It just started about a month ago.

Thanks

 

Pretty sure it's the wiper transmission. It's happening to my 05 right now, too.

 

Wiper motor is mounted on the firewall, near the brake master cylinder. You're just feeling the vibrations of the wiper motor at work. It's like things in your door vibrating when you have your stereo cranking--vibrations from the speakers through the mounts, etc, etc.

 

That makes as much sense as anything. I wonder why it just showed up though? I bought the truck with 36,000 miles and it has an extended warranty up 100,000 miles so I'm not really to concerned about it right now. I put about 10,000 miles on the truck before it showed up so I'm just kind of curious why. I find myself getting hung up on these little things and it's hard to let go of them.

Thanks

 

You just noticed it, it's always been there..

 

Weird, never noticed it before. I was probably distracted by my mpg average getting lower the more miles I put on it

 

i feel it too, but doesnt bother me.. if i turned my wipers on and nothing happened, that would bother me

 

Any chance that Ford has a Brake Drying Function like BMW/ Mercedes? The way a BMW rep explained it, when windshield wipers detect rain, the brake pads pulse to lightly contact the rotors to dry them. Idea is to shorten braking distance in wet weather. Just curious if F150 might have this feature.

 

Noticed it as well on my 2010... vibration issue makes sense

 

Not in all models. I didn't feel it in mine until maybe two months ago. It's definitely new. I know every sound my truck makes.
