Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Lift and Secure Vehicle

Use a jack to lift the front or rear of the vehicle as necessary, depending on which brakes are affected.
Secure the vehicle with jack stands to prevent any accidents.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Inspect the wheel hub for any debris or issues.

4. Inspect and Replace Brake Pads

Remove the brake caliper bolts using the appropriate socket.
Carefully slide the caliper off the brake rotor. Do not let it hang by the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper bracket for wear. Clean it if necessary.
Install new brake pads, ensuring they are properly aligned and secured.

5. Inspect and Replace Brake Rotors (if necessary)

If the rotors are warped or excessively worn, remove them from the hub.
Clean the hub surface, ensuring it is free from rust and debris.
Install new rotors, tightening to the manufacturer's specified torque value.

6. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to the specified torque value.
Reinstall the wheel and tighten lug nuts in a star pattern to ensure even seating.

7. Lower Vehicle and Test

Lower the vehicle and remove jack stands.
Test the brakes by pressing the pedal a few times to seat the pads properly.
Take the vehicle for a short test drive to check for proper function.
