Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface.
Use wheel chocks for safety.
Wear safety gloves and goggles.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Brake pad spreader
OBD-II scanner (if checking for error codes)

2. Lift the Vehicle

Sub-step 1: Loosen the lug nuts on the front or rear wheels (depending on where pads are being replaced).
Sub-step 2: Use a jack to lift the vehicle and secure it with jack stands.
Sub-step 3: Remove the lug nuts and wheels.

3. Remove Brake Caliper

Sub-step 1: Locate the caliper mounting bolts and remove them using the appropriate socket.
Sub-step 2: Carefully slide the caliper off the rotor and suspend it using a bungee cord or wire (do not let it hang by the brake line).
Sub-step 3: Remove the old brake pads from the caliper bracket.

4. Install New Brake Pads

Sub-step 1: Compare new pads with old pads to ensure correct size.
Sub-step 2: Apply brake grease to the back of the new pads to prevent squeaking.
Sub-step 3: Insert new brake pads into the caliper bracket.

5. Reassemble Components

Sub-step 1: Reposition the brake caliper over the new pads.
Sub-step 2: Tighten the caliper mounting bolts to the manufacturer's specified torque value (typically around 25 Nm).
Sub-step 3: Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Sub-step 1: Use the jack to lift the vehicle slightly to remove the jack stands.
Sub-step 2: Lower the vehicle back to the ground.
Sub-step 3: Torque the lug nuts to the specified value (typically around 120 Nm).
