Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure with jack stands.
Remove the wheel using a socket set.
Tools Required: Socket set, jack, jack stands.

3. Inspect Brake Components

Visually inspect the brake pads for thickness; replace if less than 3mm.
Check the brake rotors for any signs of scoring or warping using a caliper.
Tools Required: Caliper gauge, flashlight.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts with a socket set and carefully slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Install new brake pads into the caliper bracket.
Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).
Tools Required: Socket set, torque wrench.

5. Resurface or Replace Brake Rotors (if necessary)

If rotors are scored, consider resurfacing or replacing them.
To replace, remove the rotor by unbolting it from the hub.
