Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack stands, brake cleaner, and safety goggles.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid any electrical issues during the repair.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheel using the appropriate socket.

3. Remove Brake Components

Sub-steps:
- Use a socket wrench to remove the caliper bolts.
- Carefully slide the caliper off the brake rotor and support it with a wire or bungee cord to avoid straining the brake line.
- Remove the brake pads from the caliper bracket.

4. Inspect and Replace

Sub-steps:
- Measure the thickness of the brake pads; if they are below 3mm, replace them.
- Inspect the brake rotors for any warping or significant wear; if damaged, replace them.
- Clean the caliper and bracket with brake cleaner to remove any dust or debris.
- Install new brake pads and ensure they are properly seated in the bracket.

5. Reassemble Components

Sub-steps:
- Slide the caliper back over the new brake pads.
- Reinstall and torque the caliper bolts to the manufacturer's specifications (typically around 25-35 ft-lbs).
- Reattach the wheel and lower the vehicle.

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to seat the brake pads.
Check brake fluid level and add if necessary.
