Solution

1. Preparation

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

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Completely remove the lug nuts and take off the wheel.

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 suspend it using a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads and inspect them for wear.
4. If worn down to the metal or less than 3mm, replace with new pads.
5. Apply brake grease to the back of new pads and install them.

4. Inspect and Replace Brake Rotors

Sub-steps:
1. Check rotors for damage; if they are warped or excessively worn, remove them.
2. Use a rotor removal tool if necessary to detach the rotor from the hub.
3. Install new rotors, ensuring they are clean from any oil or debris.
4. Torque rotor retaining bolts to manufacturer specifications (check service manual for exact torque values).

5. Reassemble Braking System

Sub-steps:
1. Reattach the caliper over the new brake pads.
2. Tighten caliper bolts to the manufacturer’s specifications.
3. Reinstall the wheel and hand-tighten lug nuts.
4. Lower the vehicle and then tighten the lug nuts to the specified torque.
