Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts with a socket set before lifting the vehicle.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Locate the brake caliper and remove the bolts using a socket wrench.
2. Slide the caliper off the rotor and support it with a bungee cord or similar tool to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Check for any shims or clips and replace them if necessary.
5. Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for damage or excessive wear.
2. If the rotor is damaged, remove the caliper bracket and unscrew the rotor from the hub.
3. Install the new rotor onto the hub, ensuring it is seated properly.
4. Reattach the caliper bracket over the new rotor.

5. Reassemble and Test

Sub-steps:
1. Reinstall the caliper and secure it with bolts, tightening to manufacturer specifications (typically 25-35 ft-lbs).
2. Replace the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to the manufacturer's specification (usually around 75-85 ft-lbs).
4. Pump the brake pedal several times to ensure proper brake pad seating.
