What is the method for replacing brake pads by yourself?
4 Answers
The method for replacing brake pads by yourself is: 1. Use a wrench combined with a socket to remove the bolts of the brake caliper and take off the brake pads; 2. Install the new brake pads in place and tighten the guide bolts to complete the replacement. The function of brakes is to reduce speed or stop the vehicle. Its working principle is to use the friction between the brake pads and the brake drum, as well as between the tires and the ground, to convert the kinetic energy of the moving vehicle into heat energy after friction, thereby slowing down or stopping the car. The reasons for brake failure are: 1. Impurities in the brake master cylinder or poor sealing; 2. Failure of the vacuum booster pump; 3. Brake fluid is too dirty; 4. Oil leakage from the brake master cylinder or wheel cylinder; 5. Air leakage from the air reservoir or pipeline interface; 6. Severe overload; 7. Carbonization of the brake drum; 8. Lack of brake fluid in the brake master cylinder; 9. Wear of the brake master cylinder piston.
I usually enjoy working on my car myself, and it gives me a great sense of accomplishment. Changing brake pads isn’t actually difficult—the key is to prepare safely. First, find a flat spot to park, engage the handbrake, and chock the tires to prevent rolling. The tools you’ll need include a jack, jack stands, a wrench set, gloves, and new brake pads. Second, use the jack to lift the car, but remember to place jack stands under the chassis for stability—don’t rely solely on the jack to avoid accidents. After removing the wheel, the brake caliper will be exposed. Use the wrench to loosen the caliper bolts, gently move the caliper aside, and take out the old brake pads. At the same time, check the condition of the brake rotor—if it’s heavily worn, it’s best to replace it as well. Clean off the old dust, install the new brake pads, and re-tighten the caliper bolts. Be careful not to touch the friction surface—you can apply some lubricant to the bolt threads. Reinstall the wheel, lower the car, and don’t rush into driving fast. First, test the brakes a few times at low speed to ensure they engage properly. Regularly checking your brake pads can save you a lot of money, and every time I finish replacing them, I feel much more at ease while driving.
As someone who has worked in auto repair shops for many years, I've seen many people run into problems when changing brake pads themselves, so here are a few reminders. Basic steps: Ensure all tools are ready, with the jack and safety stands being the most important. After lifting the car, remove the wheel, use a wrench to take off the caliper bolts, and remove the old pads. The key is to document the entire process to avoid mixing up bolt positions. When installing new brake pads, check if the caliper pistons are reset; you can push them back in with a tool. Then secure the bolts and reinstall the wheel. After lowering the car, pump the brake pedal a few times to seat the pads against the rotors. Next, test drive at low speed to listen for any unusual noises. Potential risks: If the brake rotors are uneven, it can cause brake shudder; if the bolts aren't tightened properly, the caliper may come loose. Beginners should start with simpler car models to avoid mistakes. Safety always comes first—don't rush the job; taking it step by step is more reliable.
I was very careful when replacing the brake pads myself—it's not that complicated a job. Gather the necessary tools: a jack, wrench set, and safety stands are essential. Park on level ground and chock the tires to prevent accidents. After lifting the car, always place safety stands under the chassis for support. Remove the wheel to expose the brake caliper. Use a wrench to loosen the bolts, then detach the caliper and remove the old pads. After cleaning off dust, install the new brake pads in place and reattach the caliper, tightening the bolts securely. Reinstall the wheel and lower the car. Initial testing: start the engine and press the brake pedal a few times to seat the pads against the rotor. Then, take a short test drive at low speed, gently applying the brakes to check performance. Throughout the process, wear gloves to prevent burns and ensure the workspace is well-ventilated. If the brake rotor shows uneven wear, it's advisable to inspect and address it as well. Doing it yourself saves money and builds skills.
