Ok so I tried the "home remedy" tonight doing the hard stops. I did not do as many as you guys said to do, I did two. It seemed to help mostly, but there is still some squeak but not as much as before. We'll see how it holds up tomorrow. My car has 22K miles and I have not yet changed any pads--I bought the car pre owned with about 11K miles. I doubt they changed anything before I bought it so do you guys think I'm probably due for brakes soon?

Everybody gets a different service life from their brakes. To know if they are needing new pads, take off the wheel and look at the thickness of all four pads on an axel. If any are less than 2mm thick, it is time for an appointment. If they are less than 1mm, do it today.

To check the rotors you need a micrometer and a dial indicator. Measure the thickness with the "mic". If near or less than the minimum thickness, you need new rotors. If they are thick enough, use the indicator to check runout. Ask the rotor salesman what the specification is for your car. Figure on needing a rotor change every other set of pads on the front, and three or four sets on the rear. The rotors are not expensive, even at the dealer, so it no longer makes sense to refinish them in the workshop.

Thanks for the info. I have had the dealership look at the brakes a few times and they said they are fine, but I just feel like it is getting to the mileage where the car might need them. I think my service advisor said it was only about $400 for all 4 pads which seemed pretty reasonable to me.

Oh also I was told there is an indicator in the dash that should come on when you need to change them. Is the indicator accurate?
