Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves for protection.

2. Remove the Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and hang it using a bungee cord to avoid stressing the brake line.
- Inspect the brake pads for thickness; replace if they are below the minimum thickness (usually 3mm).
Replace Brake Pads:
- If replacement is needed, remove the old pads from the caliper bracket.
- Apply brake grease to the back of the new pads and install them in the caliper bracket.
- Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (usually around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged, remove the rotor by unscrewing any retaining screws.
Install new rotors by aligning them with the hub and securing them.
Ensure that the rotor surface is clean and free of any debris.

5. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and then fully tighten the lug nuts in a crisscross pattern to the manufacturer's torque specifications (usually around 100-110 ft-lbs).

6. Test Brake Functionality

Start the vehicle and press the brake pedal several times to ensure proper seating of the new pads.
Check for any unusual noises or issues while driving at low speeds.
