Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect the Rotors:
- Measure rotor thickness with a micrometer.
- Check for scoring or discoloration.
Replace Rotors if Necessary:
- Remove caliper bolts and detach the caliper.
- Support the caliper using a bungee cord to avoid strain on the brake line.
- Remove the old rotor by unscrewing the retaining screws (if applicable) and sliding it off.
- Install the new rotor, ensuring it's seated properly. Torque retaining screws to manufacturer specifications (typically around 10-15 Nm).

4. Replace Brake Pads

Remove Old Pads:
- Compress the caliper piston using a brake caliper tool or C-clamp.
- Remove the brake pad clips and old pads from the caliper bracket.
Install New Pads:
- Apply brake grease to the back of the new pads to prevent noise.
- Install new pads and secure with clips. Ensure they are properly aligned.

5. Reassemble Components

Reattach the caliper over the new pads and torque caliper bolts to manufacturer specifications (typically around 25-30 Nm).
Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically around 120 Nm).
Lower the vehicle back to the ground.

6. Testing

Reconnect the battery.
Pump the brake pedal to restore brake pressure.
Perform a test drive to ensure the issue is resolved.
