Solution

1. Preparation

Tools Required: Wheel chocks, jack stands, lug wrench.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent the vehicle from rolling.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader.

Remove the caliper bolts using a socket.
Carefully slide the caliper off the rotor. Support it with a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any damage or sticking pistons.
If pads are worn, install new brake pads, ensuring they are correctly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Torque wrench, impact driver (if needed).

If rotors are damaged or warped, remove the caliper bracket by removing its bolts.
Slide off the rotor.
Install the new rotor, ensuring it is seated properly.
Reattach the caliper bracket and torque the bolts to the manufacturer’s specifications.

5. Reassemble and Test

Reposition the caliper over the new pads and secure it with bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer's specifications.
