Leane from Helming’s Auto Repair shows us the difference between used and new brake pads.
I love these visuals here here’s a brake pad with 0% remaining there is no brake pad on
This whatsoever here on the right is a brand new out of the box brake pad see all of that is what presses on your rotors to stop your car so here’s where it goes on the car here
This here is the rotor here is brake pad these are the calipers right here and so when you wear your breaks down all the way through your pads it starts to make grooves in the shoes here in the rotors here and then you get vibration
We often change the rotors we don’t machine them because they don’t last very long when you do
That in a way that is your lesson for the day
