Solution

1. Preparation

Gather necessary tools and parts.
Ensure the car is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Rotors

Inspect: Check the brake rotors for warping using a dial indicator.
Replace: If warped, remove the caliper by unbolting it and hanging it with a wire (do not let it hang by the brake line). Remove the rotors by unbolting them.
Install New Rotors: Place the new rotors onto the hub. Torque the bolts to manufacturer specifications (typically around 80-100 ft-lbs).

4. Inspect and Replace Brake Pads

Inspect: Check brake pads for wear. If they are below 3mm, they should be replaced.
Replace: Remove old pads from the caliper bracket. Insert new pads into the bracket, ensuring the clips are secure.

5. Reassemble Components

Reattach the caliper firmly over the new pads and rotors.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specification.

6. Final Checks

Reconnect the battery.
Test the brakes by pressing the pedal a few times to seat the pads against the rotors.
