Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Use wheel chocks to secure the vehicle.
Disconnect the battery to avoid any electrical issues during the repair.

2. Wheel Removal

Use a lug wrench to loosen the wheel lug nuts.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

3. Brake Pad Replacement

Remove the caliper bolts with a socket set and slide the caliper off the rotor.
Support the caliper using a bungee cord or similar tool to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Check the caliper slides for corrosion and clean or lubricate as necessary.
Install new brake pads ensuring they are seated properly in the caliper bracket.

4. Rotor Inspection or Replacement

Inspect the rotor for grooves or warping. If damaged, proceed to replace it.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install the new rotor (if replacing) and torque the screws to the manufacturer’s specifications.

5. Reassembly

Reinstall the caliper over the new brake pads and torque the caliper bolts to the specified torque settings.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.

6. Final Checks

Reconnect the battery and check the brake fluid level, adding if necessary.
Pump the brake pedal a few times to seat the pads properly before driving.
