How to Replace Brake Pads?

Connect the vehicle using the onboard computer, select the "Open Rear Wheel Brake Caliper" option in the settings interface, and wait for 5 seconds until you hear the sound of the caliper separating. Loosen the two screws of the brake caliper. If the caliper does not separate completely, you can manually pry it open slightly using a flathead screwdriver. Open the brake caliper cover and install the new brake pads. Ensure the side with text markings faces outward, and the side without text faces inward. After installing the new brake pads, use the computer to set [Close Rear Wheel Brake Caliper], and the brake motor will reset in about 5 seconds.
I usually enjoy DIY car repairs like changing brake pads to save money and have fun. The process isn't too difficult but requires caution. First, park the car on level ground, engage the parking brake, and use a sturdy jack to lift the vehicle frame - always use jack stands for safety, never rely solely on the jack as it's dangerous. After removing the wheel, you'll see the brake caliper; loosen the bolts with a wrench and gently move the caliper aside without straining the hose. Then remove the old brake pads and check wear thickness - replace if below 3mm. Clean the bracket and slide rails, apply special copper lubricant to prevent sticking, then install new pads (make sure to get the correct model for your car). Reattach the caliper, tighten the bolts, reinstall the wheel, and lower the car. Pump the brakes a few times to seat the new pads against the rotor. The whole process takes about an hour using basic tools like wrenches, sockets, and a C-clamp to retract the piston. DIY saves $300-500 in shop fees while teaching you about your car, but avoid forcing components to prevent rotor damage or brake failure. Always test brakes at low speed before driving - if you hear noise or feel sponginess, the installation might be uneven and needs rechecking.
