It would depend on the driver's habits and the vehicle. I would recommend they be inspected by a mechanic every 10K or once a year.
There is no magic number as to how often you should change your brakes. Brakes will wear down differently depending on the make of the brake and they will start squeaking so you know that you need to change it.
How often brakes should be changed depends on the type of brakes in the vehicle and the use of the bakes in the vehicle. However, the general rule is every 10,000 miles.
Every 12 months.
You should inspect the pads and rotors at least twicw a year and change pads if they are worn down to 2mm.
The brakes should be inspected every oil change and replaced when necessary.
When they are wore out. Usually when the friction material is thinner than the metal backing plate.
It depends on the type of driving. If it's heavy "stop and go", you should probably have the brakes checked every 10,000 miles; on the other hand if it's mostly freeway you can go 50,000 or more.
You should check your brakes at least one time each year. You should also check them whenever you have your tires rotated.
Although there is no set on how often your brakes should be replaced, I would just pay attention to your car. When you notice something wrong, I would call your auto body shop.
you should change your braks every 4-6months. your welcome!
IF YOU SERIOUSLY HAVE TO ASK THAT QUESTION, YOU SHOULD NOT BE TOUCHING THE BRAKES !!! TAKE IT TO A REPAIR FACILITY THAT SPECIALIZES IN BRAKE REPAIR !
