Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench.
Raise the vehicle using the jack and secure it with jack stands.
Remove the wheel using the lug wrench.

2. Inspect and Remove Brake Components

Sub-steps:
1. Inspect the brake pads for wear; if they are less than 3mm thick, replace them.
2. Remove the caliper bolts using the socket set and carefully slide the caliper off the rotor.
3. Hang the caliper using a bungee cord or similar to avoid stress on the brake line.
4. Remove the brake pads from the caliper bracket.

3. Inspect and Replace Brake Rotor

Sub-steps:
1. Check the rotor for any scoring or warping; it should be smooth to the touch.
2. If damaged, remove the rotor by unscrewing the retaining screws and pulling it off the hub.
3. Clean the hub surface and install a new rotor, ensuring it is seated properly.
4. Torque the rotor retaining screws to the manufacturer's specifications (typically around 10 Nm).

4. Install New Brake Pads

Sub-steps:
1. Apply brake grease to the backing of the new brake pads to prevent noise.
2. Install the new brake pads in the caliper bracket.
3. Reinstall the caliper over the new brake pads and secure it with the caliper bolts.
4. Torque the caliper bolts to the manufacturer’s specifications (typically around 30 Nm).

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually 120 Nm).
2. Lower the vehicle from the jack stands.
3. Pump the brake pedal a few times to ensure proper pad seating before road testing.
