Solution

1. Preparation

Gather tools and parts required for the job.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to ensure safety.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
Brake pad wear gauge

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and support it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using the socket set.
Carefully slide the caliper off the rotor and suspend it with a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper slides for dirt and corrosion; clean or replace as necessary.
Install new brake pads into the caliper bracket, ensuring proper orientation.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are damaged, use the socket set to remove the rotor retaining screws (if applicable) and pull the rotor off the hub.
Clean the hub surface with brake cleaner before installing new rotors.
Install new rotors, ensuring they seat properly against the hub.

5. Reassemble Braking System

Slide the caliper back over the new brake pads and rotor.
Reinstall caliper bolts and tighten them to the manufacturer's specified torque value.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and tighten the lug nuts in a criss-cross pattern to the specified torque.
Reconnect the negative battery terminal.
Press the brake pedal several times to seat the brake pads.
