Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear wheels for added safety.

2. Remove the Wheel

Tools Required: Lug wrench
Sub-steps:
1. Loosen the lug nuts slightly while the wheel is still on the ground.
2. Use the jack to lift the front or rear of the vehicle as appropriate.
3. Secure with jack stands.
4. Remove the lug nuts completely and take off the wheel.

3. Remove the Brake Caliper

Tools Required: Socket set
Sub-steps:
1. Locate the caliper mounting bolts (generally two bolts).
2. Use the appropriate socket to remove the caliper mounting bolts.
3. Carefully slide the caliper off the rotor and support it using a bungee cord or rope to avoid stress on the brake line.

4. Replace Brake Pads

Tools Required: C-clamp or brake caliper tool
Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Compress the caliper piston using a C-clamp or brake caliper tool to make room for the new pads.
3. Install the new brake pads into the caliper bracket, ensuring they are properly aligned.

5. Reinstall the Brake Caliper

Tools Required: Socket set
Sub-steps:
1. Position the caliper over the new pads and rotor.
2. Reinstall the caliper mounting bolts and tighten them to the manufacturer's torque specifications (typically around 25-30 Nm).

6. Reinstall the Wheel

Tools Required: Lug wrench
Sub-steps:
1. Place the wheel back on the hub.
2. Hand-tighten the lug nuts.
3. Lower the vehicle off the jack stands and onto the ground.
4. Tighten the lug nuts to the manufacturer's torque specifications (typically around 130 Nm).

7. Final Checks

Ensure that all tools are removed from the work area.
Pump the brake pedal a few times to ensure proper brake engagement before driving.
