Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather necessary tools and parts.
Safety warning: Ensure the vehicle is securely supported on jack stands before performing any work.

2. Lift Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Using a lug wrench, remove the lug nuts and take off the wheel.
Tools required: Lug wrench.

4. Inspect and Replace Brake Rotors

Check the brake rotors for warping using a dial indicator or by visually examining them for uneven surfaces.
If warped, remove the caliper by unbolting it from the bracket (usually requires a socket set).
- Tools required: Socket set.
Carefully slide the rotor off the hub. If it’s stuck, gently tap it with a rubber mallet.
Install the new rotor by sliding it onto the hub, ensuring it's seated properly.

5. Inspect and Replace Brake Pads

Check the thickness of the brake pads. Replace if they are worn below the manufacturer’s specifications (usually 3 mm).
Remove the old brake pads by sliding them out of the caliper bracket.
Apply brake grease to the backs of the new pads to prevent noise.
Install the new brake pads into the caliper bracket.

6. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
Reattach the wheel and tighten the lug nuts in a star pattern to ensure even pressure.
Lower the vehicle and perform a test drive to verify repairs.
