I drive a 1998 Ford Escort with ~60,000 miles.
In mid May, I brought my car for an oil change and to look at my squeaky shocks before I went on a 3,000 mile road trip. Ended up getting them all replaced. I also asked the mechanic to see why my parking brake light was always on and they told me it was just faulty wiring, but didn’t do anything to fix it.
So I’m due for another oil change today and wait for my car in the next door Starbucks. Once my car is ready, I went to run some errands. I braked to pull into a parking lot and I could literally something grinding on the rotor, metal to metal. It sounded like I was dragging metal beneath my car. I am very confused because there have been no warning signs.
Just picked up the car and they replaced both rotors. They gave me a $75 dollar off coupon because in May they apparently only tested the switch for my parking brake and nothing else. This is the part that seems weird to me.
I was hoping someone could explain to me how my brake pads could wear out without warning. Obviously, my car is old and things do need replacing sometimes, but the timing feels off. Should the mechanic have checked the fluids and front brakes when I asked about the parking brake light? Could this have caused my brake pads to wear and cause the rotor damage?
Sneak Edit: Car also goes through coolant pretty quickly. Probably not related, but the shop did know of this as well.
