Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from the bracket.
Carefully slide the caliper off the rotor and suspend it with a bungee cord to avoid damaging the brake line.
Take out the old brake pads from the caliper bracket.
Compare the thickness of the old pads with new ones; replace if they are worn down.
Apply a thin layer of brake grease on the back of the new pads to prevent squealing.

4. Inspect and Replace Brake Rotors (if necessary)

Check rotors for grooves, rust, or any signs of wear.
If replacement is needed, unbolt the rotor from the hub.
Install the new rotor by aligning it with the hub and securing it with bolts to the manufacturer’s torque specifications.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and rotor.
Tighten caliper bolts to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts in a crisscross pattern to ensure even pressure.
Pump the brake pedal a few times to seat the brake pads against the rotors.
