Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Wear safety glasses and gloves.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Examine the brake rotors for any signs of warping or uneven wear.
If rotors are warped, remove the caliper by unscrewing the caliper bolts with a socket wrench.
Carefully hang the caliper using a wire or bungee to avoid stressing the brake line.
Remove the rotor by unscrewing any retaining screws and pulling it off the hub.
Install new rotors, ensuring they are properly aligned and secured.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket after removing the caliper.
Check the thickness of the pads; replace if below the manufacturer's minimum thickness.
Install new brake pads into the caliper bracket, ensuring they are seated correctly.

5. Reassemble and Torque

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's specified torque settings.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle

Carefully lower the vehicle back to the ground.
Use a torque wrench to tighten the lug nuts to the manufacturer's specifications.
