Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, brake cleaner, safety glasses, gloves.
Sub-steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Sub-steps:
1. Loosen the lug nuts slightly on the affected wheel.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the wheel to access the brake components.

3. Inspect Brake Components

Sub-steps:
1. Visually inspect the brake pads; replace if the friction material is worn down to 1/8 inch or less.
2. Check the brake rotors for scoring or uneven wear; replace if damaged.
3. Ensure brake calipers are moving freely and not seized.

4. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. Remove the caliper bolts and carefully slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. If rotors are being replaced, remove the rotor by removing the retaining screws (if applicable).
4. Install the new rotor, ensuring it is seated properly.
5. Install new brake pads into the caliper bracket.
6. Reattach the caliper over the new pads and tighten the bolts to manufacturer specifications (typically around 20-25 ft-lbs).

5. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle back to the ground using the jack.
3. Tighten the lug nuts to the manufacturer’s recommended torque value (usually around 76 ft-lbs).
