Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety.
Elevate the vehicle using a jack and secure with jack stands.

2. Remove Wheel

Sub-steps:
1. Use a lug wrench to loosen the wheel lug nuts.
2. Lift the vehicle with a jack and secure it with jack stands.
3. Remove the lug nuts and wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper by unscrewing the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pad backing plates for damage; replace if necessary.
5. Install new brake pads into the caliper bracket, ensuring they are seated correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor for grooves or warping using a straightedge.
2. If replacement is needed, remove the rotor by unscrewing the retaining screws.
3. Install new rotor, ensuring it is correctly aligned and fastened.

5. Reassemble Components

Sub-steps:
1. Reinstall the brake caliper over the new pads.
2. Tighten the caliper bolts to the manufacturer’s specified torque (typically around 20-30 ft-lbs).
3. Reattach the wheel and hand-tighten the lug nuts.

6. Final Checks

Sub-steps:
1. Lower the vehicle and remove jack stands.
2. Tighten the lug nuts to the manufacturer’s specified torque (usually around 76-85 ft-lbs).
3. Reconnect the battery and check brake fluid levels, topping off if necessary.
