Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove Wheel

Using a lug wrench, remove the lug nuts and take off the wheel.
Store lug nuts in a safe place.

4. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper bolts using a socket set.
Sub-step 2: Carefully slide the caliper off the rotor and suspend it using a bungee cord or similar tool to avoid damaging the brake line.
Sub-step 3: Remove the old brake pads from the caliper bracket.
Sub-step 4: Compare new pads with old ones for compatibility and install new pads in reverse order of removal.

5. Inspect and Replace Brake Rotors (if necessary)

Sub-step 1: Check the rotor surface for grooves or damage; if damaged, replace the rotor.
Sub-step 2: Remove the rotor by unscrewing the retaining screws or bolts.
Sub-step 3: Install the new rotor and tighten according to manufacturer specifications (typically around 80-100 ft-lbs).

6. Reassemble and Lower Vehicle

Reattach the caliper over the new pads and secure with bolts.
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).
