Brake pedal vibration and grinding noise

Finished the job of doing the frond end suspension, took me a couple days but it was a PITA, but before that I've noticed that whenever I'm braking and turning the steering wheel almost all the way to the left or right the brakes start to make a grinding sound and the brake pedal vibrates/pulsates.. It only does it at slow speeds and I notice it when I'm usually parking but it tends to go away after correcting the wheel or just after a couple seconds. My brake pedal never vibrates braking at normal road speeds and only when turned enough. Any advice? I

 

I was thinking maybe rotors? But I could be wrong.

 

It sounds like the ABS modulators may be activating even though there isn’t wheel lock-up. A build-up of iron filings on the wheel speed sensors can cause this (usually the filings are from a failing wheel bearing) as well as a faulty sensor or damaged tone wheel.

You could pull the ABS fuse and see if the symptoms stop.

Since it’s during turns, a CV joint or even a wheel bearing could also be the culprit. But the vibrating brake pedal makes me think it’s the ABS.
