1. Gather the Necessary Tools:
- You'll need a set of wrenches, a pry bar, a C-clamp, and new brake pads.
2. Park the Vehicle:
- Park your Infiniti G20 on a level surface, turn off the engine, and apply the parking brake.
3. Remove the Wheel:
- Use the lug wrench to loosen the lug nuts on the rear wheel.
- Lift your car off the ground using a jack and place it on jack stands to ensure stability while you work.
- Remove the lug nuts and take off the wheel.
4. Locate the Brake Caliper:
- The brake caliper is located behind the wheel. It is a metal housing that contains the brake pads.
5. Remove the Brake Caliper:
- Use a wrench to loosen the two bolts that hold the brake caliper in place.
- Carefully lift the brake caliper off the rotor and suspend it with a piece of wire to keep it from hanging by the brake line. Be cautious not to let it hang freely, as this can damage the brake line.
6. Remove the Old Brake Pads:
- Inside the caliper, you will see two brake pads. Use the pry bar to gently pry them out. Be mindful as they might be stuck.
7. Inspect the Brake Rotor:
- While the brake pads are out, inspect the brake rotor for wear or damage. If the rotor is worn, it will need to be replaced.
8. Compress the Brake Piston:
- Before installing the new brake pads, you will need to compress the brake piston. Use the C-clamp to push the piston back into its housing until it is fully compressed.
9. Install the New Brake Pads:
- Insert the new brake pads into the caliper, ensuring they are correctly seated.
10. Reinstall the Brake Caliper:
- Place the brake caliper back over the rotor and align the mounting holes. Tighten the two bolts you loosened earlier to secure the caliper.
11. Replace the Wheel:
- Put the wheel back on and tighten the lug nuts.
12. Test the Brakes:
- Lower the vehicle from the jack stands, start the engine, and cautiously press the brake pedal to ensure proper operation of the new brake pads.
Remember, if you are not comfortable performing this task yourself, it is advisable to have it done by a professional mechanic.
