Another Brake Pedal/Windshield Wiper Question

[SERG09]

I did a search but came up empty and I was sure I saw someone else with this issue.

Can someone give me insight as to why my brake pedal pulses with the use of the wipers. I'd like some ideas before she goes back in for some other warranty work. Any suggestions welcome. Thanks

This is a SCREW with a 6.2

Don't ride your brakes when its raining and you will be ok.

I had a F150 King Ranch it did the same thing. I just got used to it.

it's probably caused by momentary power fluctuations caused by the strain the wiper motors are under when the wipers change direction. i bet a deep cycle battery would fix the problem. it must be how Ford wires the brake system and wipers maybe they are on the same "harness".

How's my aim Ford Tech guys?

My bet is that it is not a pulse in brake pressure but a vibration felt in the pedal. The wiper motor and pedal assembly are both mounted to the cowl/firewall. As the wipers move back and forth you feel the pulse/vibration from the wiper motor in the pedal.
