Hi fam!

So I recently purchased a 2005 350z
It was well loved by the original owner and was only used as a weekend car.

I on the other hand will use it as a daily.

I bought as is where is, and everything was okay except for one problem.

When braking at low speed say 10-30 mph
You would hear a grinding sound and you will feel the vibration on ther brake pedal.

Initially we thought it was the rotors.
I had 3 shops checked it and everyone said the rotors were fine and just use it. The brake pada where still safe to use.

So I used it, but after a couple of days the while driving it the following lit up on my dash:

Slip
Tcs off
Abs
Brake

But magically the grinding sound when braking is no longer happening.

Now I suspect its the abs sensor hitting the calipers or rotors? (Not sure Im not a mechanic)

Will have it checked tomorrow and will keep you guys posted.

Comment below if anyone experienced the same thing would be great to learn from someone with experience here in the group.

Thank you for the help!
