Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, socket set, torque wrench.
Raise the vehicle using the jack and secure it on jack stands.
Remove the wheels using the lug wrench.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Locate the brake caliper and remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor without straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare the thickness of the old pads to the new ones; replace if worn beyond specifications (usually less than 3mm).
5. Apply brake grease to the back of the new pads to reduce noise.
6. Install the new brake pads into the caliper bracket.

3. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for uneven wear or scoring.
2. If damaged, remove the rotors by taking off the retaining screws or clips.
3. Install new rotors, ensuring they are properly aligned and secured.
4. Torque rotor bolts to manufacturer specifications (typically around 100-120 ft-lbs).

4. Reassemble Brake Components

Sub-steps:
1. Reinstall the caliper over the new pads and rotor.
2. Tighten caliper bolts to manufacturer specifications (usually around 25-30 ft-lbs).
3. Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Test

Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts to the correct torque specification (usually 100-120 ft-lbs in a crisscross pattern).
Pump the brake pedal several times to ensure proper pad seating.
