Solution

1. Preparation

Gather all necessary tools and parts.
Lift the vehicle and secure it on jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and suspend it with a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare the thickness of the old pads with new ones; if they are below 3mm, replace them.
5. Install new brake pads into the caliper bracket.

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the caliper bracket bolts and take off the bracket.
2. Slide the rotor off the hub; if it’s stuck, gently tap it with a rubber mallet.
3. Inspect the rotor for grooves or warping; if damaged, replace it.
4. Install the new rotor onto the hub.

4. Reassemble Brake Components

Sub-steps:
1. Reinstall the caliper bracket and torque the bolts to the manufacturer's specifications (usually around 80-100 ft-lbs, but verify for your specific model).
2. Slide the caliper back over the new brake pads and secure it with caliper bolts.
3. Ensure that all hardware is tightened properly.

5. Final Checks

Sub-steps:
1. Reinstall the wheel and lower the vehicle.
2. Pump the brake pedal several times to set the new pads.
3. Check brake fluid level and add fluid if necessary.
