Did you hear unusual sounds when you got the veering?

I often drive long distance on roads which are wet and get salted and I don't need to break much during the drive. Breaking afterwards is often affected and the car pulls dramatically to one side sometimes. You mentioned a long drive in your message. I get loud grinding noises as well - but not always. This happens only during winter here in New England. Had this issue with three sets of winter tires over 5 years btw, it's not just a one time occurrence.

I suspect there is corrosion and material collecting on the calipers and brake pads (not sure if one or both). Your brakes me be fine and its only the material build up.

It takes a long time to shave off that stuff. Use a break in procedure just like you would for new pads/rotors.

Let us know what you find. I am curious how many others have noted this issue.
