Solution

1. Preparation

Gather tools: socket set, brake cleaner, torque wrench, jack and jack stands, safety glasses, and gloves.
Ensure the vehicle is on a flat surface.
Disconnect the battery before starting work on the braking system for safety.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket set.
- Tools Required: Socket set
Carefully slide the caliper off the brake rotor and hang it using a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pad backing plates for damage.
Install new brake pads, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping. If damaged, replace with new rotors.
- Tools Required: Rotor puller (if necessary)
Clean the new rotor with brake cleaner to remove any protective coating.
Install the new rotor onto the wheel hub, ensuring it is properly aligned.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer’s specified torque value (usually around 75 lb-ft for many models).
- Tools Required: Torque wrench
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle back to the ground and torque the lug nuts to the specified value.
Reconnect the battery.
Pump the brake pedal several times to ensure the pads are seated properly.
