Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Wear appropriate safety gear, including gloves and safety goggles.

2. Remove Wheel

Tools required: Socket set, lug wrench
Loosen the lug nuts on the affected wheel.
Raise the vehicle using a jack and secure it on jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Rotors (if warped)

Tools required: Torque wrench, impact wrench (optional)
Remove the brake caliper by unbolting it from the bracket (typically two bolts).
Hang the caliper using a wire to avoid straining the brake line.
Remove the brake pads from the bracket.
Unbolt the brake rotor from the hub (if applicable) and remove it.
Check for warping using a dial gauge or by visual inspection.
If warped, install new brake rotors ensuring they are torqued to manufacturer's specifications.

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads; replace if below the manufacturer's minimum specification.
Apply brake grease to the backing of new pads to prevent squeaking.
Reinstall new brake pads into the caliper bracket.

5. Reassemble and Test

Reattach the brake caliper over the new pads and rotor.
Reinstall the wheel and tighten the lug nuts in a star pattern to ensure even pressure.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Pump the brake pedal a few times to seat the pads.
