Solution

1. Preparation

Gather tools and parts required for brake replacement.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery (negative terminal) to prevent electrical issues.

2. Lift the Vehicle

Use a floor jack to lift the front or rear of the vehicle, depending on which brakes need inspection or replacement.
Secure the vehicle with jack stands to ensure stability.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Place the wheel aside in a safe area.

4. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Use a flashlight to check the thickness of the pads and look for wear indicators.
Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor without stretching the brake line.
Remove Old Pads:
- Slide out the old brake pads from the caliper bracket.
Install New Pads:
- Apply brake grease to the backing of the new pads to reduce noise.
- Slide the new pads into the caliper bracket.

5. Reassemble Brakes

Reinstall Brake Caliper:
- Place the caliper back over the new pads.
- Tighten the caliper mounting bolts to the manufacturer’s specified torque (usually around 25-35 Nm).
Reinstall Wheel:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (typically 90-120 Nm).

6. Final Checks

Reconnect the battery (positive terminal first, then negative).
Pump the brake pedal a few times to seat the pads properly.
