15,000 miles is not a hard and fast rule for when brakes need to be replaced.
The lifespan of brake pads and rotors can vary greatly depending on a number of factors, including:
* Vehicle type: Heavier vehicles put more stress on brakes, so they may wear out more quickly than lighter vehicles.
* Driving habits: Aggressive driving, such as frequent hard braking, can wear out brakes more quickly than gentle driving.
* Terrain: Driving in hilly or mountainous areas can put more stress on brakes than driving in flat areas.
* Climate: Hot weather can cause brake fluid to boil, which can damage brake components. Cold weather can cause brake pads to freeze to the rotors, which can also damage them.
In general, most brake pads and rotors should last between 30,000 and 70,000 miles. However, it's important to have your brakes inspected regularly, especially if you notice any signs of wear, such as:
* Squealing or grinding noises when braking
* A decrease in braking power
* The brake pedal feeling soft or spongy
* The brake pedal vibrating when braking
If you notice any of these signs, it's important to have your brakes inspected by a qualified mechanic as soon as possible.
Here are some tips for extending the life of your brakes:
* Avoid hard braking: When possible, brake gently and gradually. This will help to reduce wear on the brake pads and rotors.
* Drive in a low gear when descending hills: This will help to reduce the amount of braking you have to do.
* Park your car in a shady spot: This will help to prevent the brake fluid from boiling.
* Have your brakes inspected regularly: This will help to catch any problems early on, before they can cause serious damage.
