I have a 2001 suburban and I went to get it inspected last weekend and it failed. They said the parking brakes did not work. I do not even use the parking brakes. I was told that if you do not use them they will not work after a while. Does anyone know if this is true and if so what can be done about it. Thye said they had there own seperate brake pads and they told me they would have to be replaced. I mean should'nt the dealership fix this since we were never made aware of it.
