What You Need to Change Brake Pads
Changing brake pads is a crucial maintenance task for any vehicle. Worn-out brake pads can lead to reduced stopping power, increased stopping distance, and even accidents. In this article, we will guide you through the process of changing brake pads, including the tools and materials needed, the steps involved, and some important safety precautions to take.
Tools and Materials Needed
To change brake pads, you will need the following tools and materials:
- C-Clamps or piston compressor
- Brake pad wear gauge
- Torque wrench
- Socket set or wrench
- New brake pads
- Brake lubricant
- Wheel chocks (optional)
- Jack stands (optional)
It’s essential to consult your vehicle’s repair manual for specific instructions and recommendations for your particular vehicle.
Preparation and Safety Precautions
Before starting the job, make sure you have a safe and stable working environment:
- Choose a level surface and apply the parking brake.
- Engage the parking brake and put the transmission in park (automatic) or first gear (manual).
- Turn off the engine and let it cool down.
- Wear protective gear, including gloves, safety glasses, and a face mask.
- Make sure the area is well-ventilated and free from any flammable materials.
Never work on a vehicle that is supported only by a jack. Always use jack stands for added safety.
Removing the Wheels and Brake Caliper
To access the brake pads, you need to remove the wheels and brake caliper: (See Also: Where To Apply Brake Caliper Grease)
- Loosen the lug nuts on the wheel using a lug wrench, but do not remove them yet.
- Raise the vehicle using a jack, and then remove the lug nuts and flat tire.
- Remove the caliper bolts using a socket wrench or ratchet and socket.
- Gently pull the caliper off the rotor, taking care not to damage the brake hose or ABS sensor wires.
Be careful not to let the caliper hang by the brake hose, as this can cause damage to the hose or ABS sensor wires.
Removing the Old Brake Pads
Once you have access to the brake pads, you can remove the old ones:
- Remove the pad retaining clips or springs.
- Pull the old brake pads out of the caliper.
- Take note of the pad wear sensors or clips, and remove them if necessary.
Be careful not to touch the brake rotor or pad surfaces with your bare hands, as the oils from your skin can cause brake noise or vibration.
Installing the New Brake Pads
Now it’s time to install the new brake pads:
- Take the new brake pads and insert them into the caliper, making sure they are properly seated.
- Replace the pad retaining clips or springs.
- Apply a small amount of brake lubricant to the back of the brake pads.
Make sure to follow the manufacturer’s instructions for the correct installation procedure and brake lubricant application.
Reinstalling the Brake Caliper and Wheels
Now that the new brake pads are installed, you can reinstall the brake caliper and wheels:
- Slide the caliper back over the rotor, making sure it is properly aligned.
- Replace the caliper bolts and tighten them in a star pattern to the specified torque.
- Replace the wheel and hand-tighten the lug nuts.
- Lower the vehicle to the ground and then tighten the lug nuts in a star pattern to the specified torque.
Double-check that all bolts and nuts are tightened to the specified torque to ensure safe and proper operation.
Bleeding the Brake System (Optional)
If you have replaced the brake pads, it’s a good idea to bleed the brake system to remove any air that may have entered the lines: (See Also: How To Brake Boost)
- Use a brake bleeding kit to remove air from the brake lines.
- Follow the manufacturer’s instructions for the correct bleeding procedure.
It’s essential to bleed the brake system to ensure proper brake function and to avoid brake failure.
Test Driving and Bedding-In the Brake Pads
After changing the brake pads, it’s essential to test drive the vehicle and bed-in the new brake pads:
- Drive the vehicle at moderate speeds and apply the brakes several times to bed-in the new pads.
- Listen for any unusual noises or vibrations, and check the brake pedal for proper feel and function.
It’s crucial to follow the manufacturer’s recommendations for bedding-in the new brake pads to ensure proper brake function and to avoid brake failure.
Conclusion and Recap
In conclusion, changing brake pads is a relatively straightforward process that requires some basic tools and materials. However, it’s essential to follow proper procedures and safety precautions to ensure a safe and successful job. Remember to:
- Consult your vehicle’s repair manual for specific instructions and recommendations.
- Take necessary safety precautions, including wearing protective gear and ensuring a safe working environment.
- Use the correct tools and materials, including C-Clamps or piston compressor, brake pad wear gauge, and new brake pads.
- Follow proper procedures for removing the wheels and brake caliper, removing the old brake pads, installing the new brake pads, and reinstalling the brake caliper and wheels.
- Bleed the brake system if necessary, and test drive the vehicle to bed-in the new brake pads.
By following these steps and guidelines, you can ensure a safe and successful brake pad replacement job.

Frequently Asked Questions: What You Need To Change Brake Pads
How often should I change my brake pads?
It’s recommended to change your brake pads every 30,000 to 50,000 miles, depending on your vehicle’s make and model, as well as your driving habits. If you notice any unusual noises, vibrations, or spongy brake pedal feel, it’s a good idea to have your brake pads inspected and replaced as needed.
What are the signs that my brake pads need to be replaced?
Some common signs that your brake pads need to be replaced include a squealing or grinding noise when you press the brake pedal, a spongy or soft brake pedal feel, or a vibration in the steering wheel or brake pedal when you brake. Additionally, if you notice that your vehicle is taking longer to stop than usual, it may be a sign that your brake pads are worn out.
Can I replace my brake pads myself or do I need a mechanic?
While it’s possible to replace your brake pads yourself, it’s recommended to have a professional mechanic do the job, especially if you’re not familiar with brake systems.
