Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Use wheel chocks to prevent the vehicle from rolling.
Gather necessary tools and safety equipment.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle.
Secure the vehicle on jack stands to ensure stability.

3. Remove Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect: Check the brake pads for uneven wear.
Replace: If uneven wear is present, remove the old brake pads.
- Use a socket set to remove caliper bolts.
- Slide out the caliper and hang it using a bungee cord or wire to avoid strain on the brake line.
- Remove the old pads and install new ones, ensuring they are the correct fit for the model.
- Ensure the caliper pistons are pushed back properly to accommodate new pads.

5. Check and Replace Rotors (if necessary)

Inspect the brake rotors for any signs of warping or excessive wear.
If necessary, replace rotors following similar removal and installation steps as the brake pads.

6. Reassemble Components

Reattach the caliper and secure it with the caliper bolts to the specified torque (usually around 25-35 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

7. Lower Vehicle and Final Checks

Lower the vehicle back to the ground and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 lb-ft).
Pump the brake pedal several times to ensure proper pad seating and brake pressure.
