Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface, and use wheel chocks.
Disconnect the battery for safety.

2. Remove Wheel

Loosen lug nuts with a lug wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket wrench.
- Tools Required: Socket set
Slide the caliper off the rotor without straining the brake line.
Remove old brake pads from the caliper bracket.
Inspect the brake pads for wear:
- If worn down to 3mm or less, replace them with new pads.
- Parts Required: New brake pads
Apply brake grease to the back of the new pads to reduce noise.
Install new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Remove the caliper bracket by unscrewing the bracket bolts.
Slide the rotor off the wheel hub.
Inspect the rotor for scoring or warping:
- Replace if necessary.
- Parts Required: New brake rotors
Install new rotors and reattach the caliper bracket.

5. Reassemble Components

Reattach the caliper over the new pads and secure it with the caliper bolts.
Tighten caliper bolts to the manufacturer's torque specifications.
Torque Specification: Typically around 25-30 ft-lbs (check specific manual).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle to the ground and remove jack stands.
Tighten lug nuts in a crisscross pattern to ensure even pressure.
Reconnect the battery.
