Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Parts Required: Brake pads, brake rotors (if necessary), brake caliper hardware, brake fluid.
Safety Warnings: Ensure the vehicle is on a flat surface and secured with jack stands before working underneath.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the brake caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor; do not disconnect the brake line unless necessary.
Inspect the brake pads; if they are worn down to the indicator, replace them.
- Sub-steps:
  - Remove old brake pads from the caliper bracket.
  - Clean the caliper bracket and apply brake grease to contact points.
  - Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if needed)

Check the rotor surface for any scoring or excessive wear.
If replacement is necessary:
- Remove the rotor retaining screws (if applicable) and slide the rotor off the hub.
- Install the new rotor, ensuring it is flush against the hub.
- Note: Torque the rotor retaining screws to the manufacturer's specifications.

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten the caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle back to the ground.
Tighten the lug nuts to the manufacturer's specified torque in a criss-cross pattern.
Check brake fluid level and add fluid if necessary.
