Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Remove Wheel Assembly

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

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, C-clamp
Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor. Do not let it hang by the brake line.
3. Remove the old brake pads and inspect the backing plates for wear.
4. Compress the caliper piston using a C-clamp to make room for new pads.
5. Install new brake pads (ensure they are the correct type for your vehicle).
6. Reattach the caliper and torque the bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Socket set, torque wrench, rotor puller (if needed)
Sub-steps:
1. If rotors are damaged, remove them by unscrewing the rotor retaining screws if present.
2. Install new rotors, ensuring they are clean and free from oil.
3. Torque the rotor retaining screws (if applicable) to manufacturer specifications.

5. Reassemble Wheel Assembly

Tools Required: Torque wrench
Sub-steps:
1. Place the wheel back on and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually around 76-80 ft-lbs).
3. Reconnect the negative battery terminal.
