Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Use wheel chocks to prevent vehicle movement.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Loosen wheel lug nuts using a socket set.
Lift the vehicle with a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket wrench.
Carefully slide the caliper off the rotor without stretching the brake line.
Check the condition of the brake rotor and replace if necessary.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket with brake cleaner to remove debris.
Install new brake pads, ensuring they are seated correctly.

4. Reassemble Braking Components

Reattach the caliper over the newly installed brake pads.
Tighten the caliper bolts to the manufacturer's specified torque (usually around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

5. Final Checks

Lower the vehicle and tighten the lug nuts to the manufacturer's specified torque (typically 80-100 ft-lbs).
Reconnect the battery.
Pump the brake pedal to ensure proper brake pad seating.
