Brakes-do front or back wear out first?

My two cents worth:

The front pads should go first. That is from Honda experience.

The brakes have a built in piece that will cause the brakes to squeek when they are ready to be replaced. You can also see the brakes by simply pulling off a wheel to inspect them. Sometimes depending upon the rims you have you can inspect them without pulling off a rim. The mileage will vary according to the type of pad installed and the driving environment is which you subject the vehicle.

The front brakes pads always wear out first on all cars that is where 70% of you braking power comes from how long they last depends on how you drive the car I personally wouldnt wait until you hear them squeek as sometimes this may mean you cant turn the rotors because the built in pad indicator that makes them squeek when its time to replace them could have been bent when installed meaning that when you do finally hear the noise it wont be from the wear indicator but the backing of the brake pad digging into the rotor this will cost more to have your brakes done if you have to replace the rotors it is best to have your brakes checked regularly or when you hear any noise from the brakes
