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.

I believe that replacing brake pads must prioritize safety and avoid taking risks for the sake of convenience. The braking system is directly related to human lives, and improper DIY work can lead to serious issues, such as hydraulic fluid leaks or sudden brake failure, potentially causing accidents. I recommend first learning how to inspect brake wear—check if the brake discs have deep grooves or if the pad thickness is below the safety limit, and replace them promptly if needed. During replacement, it's advisable to have an assistant. The general process involves jacking up the car, removing the wheel, loosening the caliper, and installing new pads. However, steps involving high-pressure fluids and precise operations are best left to professionals. Technicians at specialized shops use professional tools to inspect disc flatness and caliper condition. The cost for a standard vehicle is reasonable, ranging from 200 to 800 RMB depending on the model, ensuring reliable quality. Regular checks every six months on brake fluid and pads can extend their lifespan, reduce emergencies, and prevent hazards like sudden brake failure at high speeds, similar to unrepaired headlight issues. In short, safety comes first—don’t blindly follow online tutorials for DIY. Opting for certified repair services offers greater peace of mind.

I change brake pads mainly to save money. When the budget is tight, doing it myself saves more than half compared to shop prices. The process is simple: buy matching new pads in advance, with online prices ranging from 60-200 RMB including shipping. Find an afternoon to jack up the car, remove the wheels, move the caliper, replace the pads, and reassemble—the whole process takes 1-2 hours. But a warning: if you lack experience, don’t force it as you might damage the rotor, leading to higher additional costs. The benefits are obvious—saving on labor costs—but the downside is it’s time-consuming and mistakes can happen. For first-timers, it’s advisable to seek help from an experienced friend or learn from YouTube videos. Other money-saving tips: buy parts online, check brake fluid levels and top up if low, don’t prolong intervals as it increases rotor wear and costs, and pay attention to brake squealing—it’s an early warning signal to replace them promptly. In short, from an economic perspective, DIY brake pad replacement is worthwhile with manageable risks, but make sure you have all the necessary tools like a jack and wrench—don’t force it if something’s missing.
