Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent movement and disconnect the battery.

2. Raise Vehicle

Tools Required: Floor jack, jack stands
Lift the vehicle using a floor jack and securely place it on jack stands.
Remove the wheels to access the brake components.

3. Inspect and Clean Components

Remove the brake caliper by unscrewing the caliper bolts.
Carefully slide the caliper off the rotor without straining the brake line.
Sub-steps:
- Check caliper operation by pushing the piston back in using a C-clamp.
- Clean caliper slide pins with brake cleaner and lubricate with high-temperature grease.

4. Replace Brake Pads and Rotors (if necessary)

Inspect brake pads for uneven wear; replace if they are worn down unevenly.
Check rotors for warping; replace if necessary.
Sub-steps:
- Install new brake pads ensuring they are seated correctly.
- If replacing rotors, remove the old rotor by unscrewing the retaining screws and install the new rotor.

5. Reassemble and Test

Reattach the brake caliper and torque the bolts to the manufacturer's specifications (typically 20-25 Nm).
Reinstall the wheel and lower the vehicle.
Tools Required: Torque wrench
Ensure all components are secured and there are no leaks.
