Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, brake cleaner, and new brake pads.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the vehicle battery to ensure safety.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the bolts securing it using a socket wrench.
Carefully slide the caliper off the rotor and support it; do not stress the brake line.
Inspect the brake pads for wear; if replacing, remove the old pads by sliding them out of the caliper bracket.
Clean the caliper bracket and rotor with brake cleaner.
Install new brake pads into the caliper bracket, ensuring they are properly seated.

4. Reassemble Brake Components

Reposition the caliper over the new pads and align it with the rotor.
Secure the caliper by tightening the bolts to the manufacturer’s specified torque (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

5. Lower Vehicle and Final Checks

Lower the vehicle back to the ground and tighten the lug nuts to the specified torque (usually 70-80 ft-lbs).
Reconnect the vehicle battery.
