Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface.
Wear safety gloves and goggles.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly before lifting the vehicle.
2. Use a jack to raise the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Socket set, jack, jack stands.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket.
2. Carefully lift the caliper off the rotor and support it with a bungee cord or rope.
3. Inspect the brake pads for wear; replace if they are below the manufacturer's recommended thickness (usually 3mm).
4. If replacing, remove old pads and install new ones, ensuring they are properly seated.
Tools Required: Socket set, caliper tool for compressing the piston if needed.

4. Inspect Rotors

Sub-steps:
1. Check rotor surface for grooves or scoring. If the rotor is damaged, it may need resurfacing or replacement.
2. If replacement is necessary, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
3. Install the new rotor, ensuring it is properly aligned and secured.
Tools Required: Torque wrench (for rotor screws).

5. Reassemble Components

Sub-steps:
1. Reposition the caliper over the new brake pads and rotor.
2. Tighten the caliper bolts to the manufacturer’s specified torque.
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and then fully tighten the lug nuts in a star pattern to ensure even pressure.

6. Final Check

Sub-steps:
1. Pump the brake pedal several times to seat the pads against the rotors.
2. Check brake fluid level and top off if necessary.
Tools Required: Brake fluid (if needed).
