Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper by loosening the caliper bolts with a socket wrench.
2. Carefully slide the caliper off the rotor and suspend it to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Check the condition of the brake rotor; if worn, replace it as well.
5. Install new brake pads, ensuring they are properly seated in the caliper bracket.
Tools Required: Socket set, brake pad spreader (if needed).

4. Reinstall Brake Caliper

Sub-steps:
1. Reposition the caliper over the new brake pads.
2. Torque the caliper bolts to the manufacturer's specifications (typically around 25-35 Nm).
3. Reinstall the wheel and hand-tighten the lug nuts.
Tools Required: Torque wrench.

5. Final Steps

Sub-steps:
1. Lower the vehicle off the jack stands.
2. Fully tighten the lug nuts in a crisscross pattern to the specified torque (typically around 100-120 Nm).
3. Reconnect the negative battery terminal.
4. Pump the brake pedal a few times to ensure proper brake operation.
Safety Warnings: Ensure all tools are cleared from the work area before lowering the vehicle.
