Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands
Loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set.
Carefully slide the caliper off the rotor without stretching the brake line.
Inspect the brake pads for uneven wear; replace if necessary.
- Sub-steps:
  - Remove old brake pads from the bracket.
  - Install new brake pads ensuring they are oriented correctly.

4. Check and Replace Brake Rotors (if necessary)

If the rotors are worn beyond specification, they should be replaced.
Tools Required: Rotor puller (if necessary), torque wrench
Remove the caliper bracket if the rotor is not coming off.
Install new rotors, ensuring they are clean and free of oil.
Sub-steps:
- Torque the caliper bracket bolts to manufacturer specifications (usually around 70-90 ft-lbs depending on the model).

5. Reassemble Components

Reinstall the caliper over the new brake pads.
Tighten caliper bolts to the recommended torque specification.
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern.

6. Bleed Brake System (if necessary)

Tools Required: Brake bleeder kit
If brake fluid was lost during the repair, bleed the brake system to remove air.
Sub-steps:
- Start with the wheel farthest from the master cylinder and work your way to the closest.
- Open the bleeder screw and pump the brake pedal until fluid flows without bubbles.
