Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands.
Loosen the lug nuts of the wheel using a socket wrench.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Torque wrench, brake pad spreader.
Remove the caliper bolts using a socket wrench.
Carefully lift the caliper off the rotor, securing it with a bungee cord (do not hang it by the brake line).
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any signs of damage and replace if necessary.
Install new brake pads into the caliper bracket.
Use a brake pad spreader to compress the caliper piston, allowing it to fit over the new pads.

4. Inspect and Replace Brake Rotors (if necessary)

If the rotors are worn or scored, remove the caliper bracket by unscrewing its bolts.
Slide the rotor off the wheel hub. If it's stuck, gently tap it with a rubber mallet.
Clean the hub surface and install the new rotor.
Reattach the caliper bracket and torque the bolts to the manufacturer's specifications.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts.
Reinstall the wheel and torque the lug nuts in a star pattern.
Lower the vehicle from the jack stands and reconnect the battery.
