About a friends car: Driven very infrequently. Dealer says brake pads are rusty and need to be replaced because of this and immediately because this is a dangerous condition. I drove the car and the brakes worked fine. Couldn't we take a ride on a quiet road and brake a lot to wear the rust off of the pads. Am I missing something or are we being taken for a ride.

It is common for the metallic particles in semi-metallic pads to rust, even overnight in humid conditions, and yes, driving will wear that rust off. New pads will do the same thing. As long as the linings aren't worn down too far there is nothing wrong with leaving them alone. When the grinding doesn't go away after a few miles, that's the time for an inspection to identify if they need replacement.

Pads can become so rusted they start seperating from backing plate and fall off which will result in some/much loss of stopping power. You may want to inspect yourself to see degree of deterioration.

Other items to check if your pads are worn include:
* Hardware may be causing the pads to not move freely. This can cause premature wear as the pads may be in constant contact with the rotor. It could also be a malfunctioning caliper.
* Caliper slides that are binding or seized can cause this condition.
* Caliper slides should be removed cleaned and lubricated (and replaced if corroded).
* Installing new pads on an unfinished rotor will significantly decrease the life of the pads.
* Rear brakes that are not working efficiently will cause the front brakes to work harder, causing premature wear to the front pads and rotors.
