Solution

1. Preparation

Gather tools and parts.
Ensure you have safety glasses and gloves.
Park the vehicle on a level surface and engage the parking brake.

2. Remove Wheel

Sub-steps:
- Loosen wheel lug nuts using a lug wrench.
- Raise the vehicle with a jack and secure it with jack stands.
- Remove the lug nuts and take off the wheel.

Tools Required:

Lug wrench
Jack and jack stands

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor; support it with a bungee cord to avoid stress on the brake line.
- Remove the old brake pads from the caliper bracket.
- Compare new pads with old pads to ensure correct fit.
- Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if needed)

Sub-steps:
- If the rotor is damaged, unscrew the rotor retaining screws (if applicable) and slide the rotor off the hub.
- Clean the hub surface with a wire brush to ensure proper contact with the new rotor.
- Install the new rotor onto the hub and secure it with retaining screws.

Parts Required:

Brake pads
Brake rotors (if necessary)

5. Reassemble and Test Brakes

Sub-steps:
- Reattach the caliper over the new brake pads and tighten caliper bolts to manufacturer specifications (typically 25-35 Nm).
- Reinstall the wheel and hand-tighten the lug nuts.
- Lower the vehicle and use a torque wrench to fully tighten the lug nuts to the specified torque (typically 100-120 Nm).
- Pump the brake pedal several times to seat the pads against the rotor.

Estimated Repair Time: 2-4 hours
