Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves throughout the repair process.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor, supporting it to avoid strain on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare the old pads with new ones for size and thickness.
5. Install new brake pads by sliding them into the caliper bracket.
Tools Required: Socket set, brake pad spreader or C-clamp (for compressing caliper piston).

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for grooves or warping. If damaged, remove the rotor.
2. Remove the retaining screws if applicable and slide the rotor off the hub.
3. Clean the hub surface with brake cleaner to ensure proper rotor seating.
4. Install the new rotor onto the hub, ensuring it sits flat.
Tools Required: Brake cleaner, rotor removal tool (if necessary).

5. Reassemble Components

Sub-steps:
1. Reinstall the caliper over the new pads and rotor.
2. Tighten the caliper bolts to the manufacturer's specified torque value.
3. Reinstall the wheel and hand-tighten the lug nuts.
Tools Required: Torque wrench.

6. Lower Vehicle and Final Checks

Sub-steps:
1. Carefully lower the vehicle and remove the jack stands.
2. Torque the lug nuts to the manufacturer's specifications in a star pattern.
3. Pump the brake pedal several times to ensure proper pad and caliper seating.
Tools Required: Torque wrench.
