Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel

Use a lug wrench to loosen the wheel lug nuts slightly.
Lift the vehicle with a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Remove Brake Components

Inspect Brake Pads: Check for wear indicators; if worn, replace them.
Remove Caliper:
- Use a socket set to remove caliper bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove Brake Pads: Slide out the pads from the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors: Check for grooves or warps; if damaged, replace.
Remove Rotors: If replacement is needed, remove any retaining screws and slide the rotor off the hub.
Install New Rotors: Align and secure the new rotor to the hub.

5. Install New Brake Pads

Prepare New Pads: Apply brake grease to the backing of new pads to prevent noise.
Install Pads: Slide new pads into the caliper bracket.

6. Reattach Caliper and Wheel

Reattach Caliper: Place the caliper over the new pads and secure it with bolts. Torque to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall Wheel: Place the wheel back on, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to specification (usually around 76-83 ft-lbs).

7. Final Check

Before starting the vehicle, pump the brake pedal several times to seat the brake pads against the rotors.
