Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues during the repair.

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 to access the brake components.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check the thickness; if below 3mm, replace them.
Remove Old Brake Pads:
- Unbolt the caliper using a socket set.
- Lift the caliper off the rotor without disconnecting the brake line; secure it with a bungee cord.
- Slide the old pads out of the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads to prevent noise.
- Slide the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Remove Brake Rotor:
- Unbolt the rotor from the hub (if applicable).
- Use a mallet to gently tap the rotor loose if it is stuck.
Install New Brake Rotor:
- Place the new rotor onto the hub and secure it with bolts to the specified torque (refer to manufacturer specifications).

5. Reassemble Components

Reattach the caliper over the new pads and secure it with the appropriate torque.
Reinstall the wheel, tightening lug nuts in a star pattern to ensure even pressure.
Lower the vehicle from the jack stands and remove the jack.

6. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure proper pad seating.
Check brake fluid level and top off if necessary.
