Solution

1. Preparation

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

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Ensure the vehicle is stable before working underneath.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Store lug nuts in a safe place for reinstallation.

4. Inspect and Replace Brake Components

A. Brake Pad Replacement

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor and support it without stretching the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are properly aligned.

B. Rotor Inspection/Replacement

Sub-steps:
1. Check the rotor for scoring or excessive wear.
2. If worn, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
3. Install a new rotor by reversing the removal steps.

5. Reassemble Components

Sub-steps:
1. Reinstall the caliper over the new brake pads and rotor.
2. Tighten caliper bolts to the manufacturer's specified torque.
3. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

Remove jack stands and lower the vehicle with a jack.
Tighten lug nuts to the specified torque.
Pump the brake pedal to seat the new pads, then test the brakes for function.
