Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Loosen the lug nuts slightly before raising the vehicle.
Use the jack to lift the vehicle and securely place jack stands under the frame.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake cleaner, torque wrench
Remove the caliper bolts using the socket set and lift the caliper away from the rotor.
Use the brake cleaner to clean the caliper and rotor surfaces.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly aligned in the caliper bracket.
Reattach the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications (usually around 18-25 lb-ft).

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Socket set, rotor puller (if needed)
If rotors are damaged or scored, remove them by loosening and taking off the retaining screws or bolts.
Clean the hub surface before installing new rotors.
Install new rotors, ensuring they seat properly on the hub.
If applicable, secure with the retaining screws/bolts to the manufacturer’s specifications.

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts in a star pattern to the manufacturer’s specifications (typically around 100-150 lb-ft).
Reconnect the negative battery terminal.
Test the brake system by pressing the brake pedal several times to seat the pads against the rotors.
