Solution

1. Preparation

Gather tools and safely park the vehicle on a level surface.
Activate the parking brake and place wheel chocks around the rear wheels.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake cleaner.
Sub-steps:
1. Remove the brake caliper bolts and carefully detach the caliper from the rotor.
2. Support the caliper using a bungee cord or rope to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper slide pins; clean and lubricate if necessary.
5. Install new brake pads, ensuring they are positioned correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Socket set, torque wrench.
Sub-steps:
1. If the rotors are damaged, remove them by unscrewing the retaining screws (if equipped) and sliding them off the hub.
2. Clean the hub surface with brake cleaner.
3. Install new rotors, ensuring they are properly seated.
4. Torque rotor retaining screws to manufacturer specifications.

5. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reattach the brake caliper over the new pads and torque the caliper bolts to specification.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and torque the lug nuts to specification in a crisscross pattern.
4. Pump the brake pedal to seat the pads properly before driving.
