Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper by unbolting it from the bracket (usually two bolts).
2. Carefully slide the caliper off the rotor, avoiding strain on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper and bracket for damage.
5. If needed, replace brake pads with new ones, ensuring they are oriented correctly.

4. Inspect and Replace Rotors (if necessary)

Sub-steps:
1. Measure rotor thickness with a micrometer to ensure it meets specifications.
2. If rotors are thin or damaged, remove them by unbolting the rotor from the hub.
3. Install new rotors, ensuring they are clean and free of grease.
4. Torque rotor bolts to manufacturer specifications.

5. Reassemble Braking System

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