Brake peddlle

How about the fronts? Have you torn into them and checked them out?

I was told they were good when I recently got new tires but not sure how well they checked them out

I would get the front end up on jack stands and run the tires in the air and hit the brakes. Try to have a buddy listen and see if you can recreate the issue. If the crunch is coming from the front, I would start tearing it down and inspecting it. If no noise while in the air, it may be something like a bad wheel bearing or CV joint. Check the boots for splits.

I will see about getting this done, thank you so much!

Could be a cracked sensor or sensor ring on the abs brakes making them kick in, that usually sounds like a grinding noise.

Thank you, that makes perfect sense since my abs light keeps coming on as well.

You are welcome! In the future, if you post, you should be sure to give as many details as possible because it helps give you the best answer. I had several of my own cars with the same problem and it is actually very common, but a lot of people haven't run across it.

If you have drum brakes the plate that is in back were the bakes sit on might be bent and it is pushing the brake shoes out of place it happen to me after a few potholes the plate is loose or bent i replaced the plate no more crunching sounds

plus if you are using pro brakes shoes crunching will happen
