If you're talking front ones, and they were installed properly and the system doesn't develop other problems to cause premature wear, and also depending if you're talking city or highway driving, not to mention what quality of parts were installed, I would expect about 35,000. If you have rear drum brakes and you keep them adjusted every 12,000 miles your fronts may last longer. If we are talking rear shoes I would expect 75,000 miles, rear disc brakes about 50,000 miles
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.
It depends on the vehicle and the driver. Some folks wear out brakes in less than 15K and some folks go 75K before they need replacing. Have your brakes checked each time you have the vehicle serviced.
You should check your brakes at least one time each year. You should also check them whenever you have your tires rotated.
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.
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.
Rear pads usually last about 100,000 kms. Inspect them at least once a year and check pad wear and freedom of emergency brake.
Bleed the brakes. It sounds like you have air in the system.
weekly
You should bring your car in to a shop or a place like auto zone etc. They will inform you on the condition of your brakes and when they need to be changed out.
Passwords should be changed every month.
According to my dealer, it should be changed at 150,000 km.
It depends. High quality brakes can last a very long time if you drive your car properly and do not rabbit drive. If they are squeaking, you should have them checked out.
