Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Lift the vehicle with a jack and secure it with jack stands.

2. Remove Wheel

Using a tire iron, loosen the lug nuts partially while the vehicle is still on the ground.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Components

A. Brake Rotor Inspection and Replacement

Check rotors for warping or scoring using a dial indicator.
If warped or damaged, remove the caliper (remove caliper bolts) and hang it securely.
Remove the rotor (may require tapping with a rubber mallet if stuck).
Install new rotors, ensuring they are clean and free of oil.
Torque rotor mounting bolts to manufacturer specifications.

B. Brake Pad Inspection and Replacement

Inspect brake pads for thickness; replace if below manufacturer specifications.
Remove old brake pads (slide them out from the caliper).
Install new brake pads, ensuring proper orientation and alignment.
Apply anti-squeal grease to the back of the pads if necessary.

4. Reassemble and Lower Vehicle

Reinstall the brake caliper and torque caliper bolts to specification.
Replace the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.

5. Final Checks

Pump the brakes to ensure proper pedal feel before driving.
Check for any abnormal noises or issues before proceeding.
