Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to avoid electrical issues.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts on the wheel corresponding to the brakes being inspected.
Elevate the vehicle using a jack and secure it with jack stands.
Fully remove the lug nuts and wheel.

3. Remove Brake Caliper

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor.
Suspend the caliper using a bungee cord or rope to avoid putting strain on the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Check the condition of the rotor; if necessary, replace or resurface it.
Install new brake pads into the caliper bracket.
Apply brake grease to the back of the new pads to reduce noise.

5. Reassemble Components

Reattach the brake caliper over the new pads and tighten the mounting bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the recommended value (usually 80-100 ft-lbs).

6. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal a few times to seat the brake pads.
Check the brake fluid level and top off if necessary.
