Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Inspect and Replace Brake Pads

Sub-steps:
- Remove the wheel to access the brake assembly.
- Inspect the thickness of the brake pads; if they are below 3mm, replace them.
- If replacing, remove the caliper bolts using a socket set and slide the caliper off.
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and apply anti-squeal lubricant to the backing of the new pads.
- Install new brake pads into the caliper bracket.
- Reattach the caliper and torque the bolts to the manufacturer's specifications (typically around 20-30 ft-lbs).

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- If rotors are scored or warped, remove them by unbolting the caliper bracket.
- Slide the rotor off the hub and inspect for any damage.
- If replacement is needed, install new rotors and torque the bolts to specifications (usually around 80-100 ft-lbs).
- Ensure to clean the new rotors with brake cleaner to remove any protective coating.

4. Final Assembly and Testing

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (typically around 75-85 ft-lbs).
Reconnect the battery.
Test the brakes by pressing the pedal several times to seat the pads against the rotors.
Ensure the brake warning light is off and that brakes feel firm.
