1. Your driving habits: If you drive aggressively, in stop-and-go traffic, or in hilly areas, your brakes will wear out more quickly.
2. Your vehicle: Some vehicles have brakes that wear out more quickly than others.
3. The weather: Driving in wet or icy conditions can also wear out your brakes more quickly.
In general, you should have your brakes inspected every 10,000 miles or every year. If your brakes are worn down to 1/4 inch or less, you should have them replaced.
Here are some signs that your brakes may need to be replaced:
* Your brake pedal feels spongy or soft.
* Your car pulls to one side when you brake.
* You hear a squealing or grinding noise when you brake.
* Your brake lights are not working properly.
If you experience any of these signs, you should have your brakes inspected by a qualified mechanic.
