On average, car brakes should be replaced every 30,000 miles, depending on factors like your specific vehicle, driving habits and weather conditions where you live. However, since this is a broad range, you may be wondering what signs to look out for that your vehicle needs brake replacement.
Read in to discover warning signs that your brakes need replacement.
1. High Pitch or Grinding Noise
If you apply the brakes and hear a high pitch or grinding noise, this is a strong indicator that the brakes have worn thin. The sound results from the built-in wear indicator coming into contact with the rotor. This sound means you have very little brake pad thickness left, which can cause damage to other parts of your vehicle.
2. Vibration
Feeling a vibration on the pedal when you apply the brakes indicates warped brake rotors. A professional inspection can help determine whether they should be resurfaced or replaced.
3. Spongy Brakes
If the brake pedal feels differently, either low or spongy, and takes more effort to apply, this means there's a potential problem with the brake system that should be promptly diagnosed.
4. Sensitive Parking Brake
Applying the parking brake, either by foot or hand, and not feeling resistance may require an adjustment or a repair. Whether you have an automatic or manual transmission, AAA recommends always applying the parking brake before exiting the vehicle.
5. Brake Pads Have Visible Signs of Wear
Consider visibly assessing your brakes for signs of wear and tear. Look between the wheel spokes to check the thickness of the brake pads. If the brake pad thickness is less than about 1/4 inch, you'll likely need to replace them. You can also check the rotor for visible cracks or grooves that indicate it needs to be replaced.
6. Vehicle Takes Longer To Stop
Have you noticed that after applying the brake, your vehicle takes longer than usual to come to a stop? If so, this is a strong indicator that something is wrong with the brakes. Slow stopping time can be a result of worn brake pads, low friction between the brake pads and rotors, leaking brake fluid or mechanical issues within the braking system.
7. Car Veers To One Side
If your car veers to one side while driving, this may mean that the brake lining is experiencing uneven wear. This typically results from an issue with the caliper and requires an adjustment.
8. Leaking Fluid
A puddle of vehicle fluid underneath your car is a tell-tale sign that there may be a leak. Brake fluid can be identified by its clear-yellow coloring and oily texture. Brake fluid leaks can be a result of issues with the brake lines, master cylinder or caliper.
9. Smoky Smell
A burning smell could be an indicator that the brakes are overheating, brake fluid is leaking or there's a buildup of brake dust.
10. Dashboard ABS Indicator Turns On
The most obvious warning sign that you have worn brakes is if the anti-lock braking system (ABS) is illuminated (usually yellow) on your dashboard. The ABS prevents the wheels from locking up so you can maintain control of the vehicle during hard stops. Therefore, you should get the system inspected ASAP if thisindicator turns on.
11. Mileage
While the specific mileage varies based on driving habits and road conditions, you should typically replace your car brakes every 30,000 miles. It is recommended to get your brakes checked each time the wheels are rotated, which is typically every other oil change.
