Essential Brake Maintenance Checking Pads and Rotors
Your car’s brakes are one of the most critical safety systems, and maintaining them properly is essential for preventing accidents and ensuring your safety. Regular brake maintenance involves checking the brake pads and rotors for wear and tear, and replacing them when necessary. Brake pads are the friction material that presses against the rotors to slow down or stop your car. Rotors are the metal discs that the brake pads clamp onto. Over time, brake pads wear down and rotors can become warped or damaged, reducing their effectiveness.
To check your brake pads, you’ll need to remove the wheels and inspect the pads for thickness. If the pads are worn down to less than 1/4 inch, they need to be replaced. You can also check the rotors for signs of damage, such as cracks, grooves, or excessive rust. If the rotors are warped or damaged, they should be replaced as well. Replacing brake pads and rotors is a relatively straightforward DIY project, but it’s important to follow the correct procedures and use the right tools. You’ll need a jack, lug wrench, brake caliper tool, and new brake pads and rotors. According to a recent study, properly maintained brakes can reduce your stopping distance by up to 25% [iii].
If you’re not comfortable performing brake maintenance yourself, it’s best to take your car to a qualified mechanic. However, you can still save money by inspecting your brakes regularly and catching problems early. Listen for any unusual noises, such as squealing or grinding, when you apply the brakes. These noises can be an indication of worn brake pads or damaged rotors. Also, pay attention to how your brakes feel. If your brakes feel spongy or unresponsive, or if your car pulls to one side when you brake, it’s time to have your brakes inspected. By being proactive about brake maintenance, you can ensure your safety and avoid costly repairs.
