Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and set the parking brake.
Use wheel chocks to prevent rolling.

2. Remove Wheel

Use a socket set to loosen lug nuts while the vehicle is on the ground.
Lift the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for wear indicators; if they are worn down to the metal, replacement is necessary.
Replace Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Slide off the caliper and support it with a hangar or rope to avoid stress on the brake line.
- Remove the old brake pads from the bracket.
- Install new brake pads into the bracket, ensuring proper orientation.
- Reinstall the caliper over the new pads and secure it with the caliper bolts. Torque bolts to manufacturer specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Measure rotor thickness with a micrometer; if below minimum specification, replace.
Replace Rotors:
- Remove the caliper bracket if rotors are attached to it.
- Remove the rotor by pulling it straight off the hub.
- Clean the hub surface with brake cleaner before installing a new rotor.
- Install the new rotor and reattach the caliper bracket, torquing to specifications.

5. Reassemble and Test

Reinstall the wheel and torque the lug nuts to manufacturer specifications.
Lower the vehicle and pump the brake pedal to restore brake pressure.
Test drive the vehicle at low speeds to ensure proper function.
