Solution

1. Preparation

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

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts using a lug wrench while the vehicle is still on the ground.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the wheel completely.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it with a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare the thickness of the old pads with new ones to confirm replacement.
5. Apply brake grease to the back of the new pads to reduce noise.
6. Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are damaged or uneven, remove the rotor by unscrewing the retaining screws.
2. Clean the hub surface with a wire brush.
3. Install the new rotor (if replacing) and secure it with retaining screws.

5. Reassemble Components

Sub-steps:
1. Reattach the caliper over the new brake pads and secure it with caliper bolts (torque to manufacturer specifications).
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to ensure even torque.

6. Final Checks

Pump the brake pedal a few times to seat the pads properly.
Check brake fluid levels and add fluid if necessary.
