Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery before working on the braking system for safety.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Torque wrench, socket set
Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully lift the caliper off the brake rotor and support it with a bungee cord to avoid stress on the brake line.
3. Check the brake pads for wear; if the friction material is less than 3mm, replace them.
4. If replacing, slide new brake pads into the caliper bracket ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor puller, torque wrench
Sub-steps:
1. If rotors are scored or warped, remove them by unscrewing the retaining screws.
2. Install new rotors, ensuring they are clean and free of grease.
3. Torque rotor screws to the manufacturer recommended specification.

5. Reassemble and Test

Tools Required: Torque wrench
Sub-steps:
1. Reattach the caliper over the new brake pads and secure it with the caliper bolts, torquing to the manufacturer specifications.
2. Reinstall the wheel and hand-tighten lug nuts.
3. Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to ensure even pressure.
4. Reconnect the battery.
