Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and securely lift the vehicle using jack stands.
Disconnect the battery for safety.

2. Inspect and Replace Brake Pads

Remove the wheel using a lug wrench.
Remove the brake caliper by unscrewing the caliper mounting bolts (usually 14mm or 17mm).
Slide the caliper off the rotor and support it with a bungee cord or a hook to avoid straining the brake line.
Take out the brake pads from the caliper bracket.
Check the thickness of the pads; replace them if they are worn down to 3mm or less.
Apply brake grease to the back of the new brake pads to minimize noise.
Install the new brake pads into the caliper bracket.

3. Inspect and Replace Brake Rotors (if necessary)

Check the brake rotor surface for grooves or warping. Replace if necessary.
To remove the rotor, unscrew the rotor retaining screws if applicable.
Slide the rotor off the hub and replace it with a new rotor.
Ensure to clean the new rotor with brake cleaner to remove any protective oil.

4. Reassemble Brake Components

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper mounting bolts to the manufacturer’s specified torque (typically around 20-25 ft-lbs).
Reinstall the wheel and tighten the lug nuts in a star pattern.

5. Final Checks

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