Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake pad gauge, torque wrench.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Allow the vehicle to cool down if it has been driven recently.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts on the wheels where brake pads are to be replaced.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect and Remove Brake Pads

Locate the brake caliper and remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the brake rotor and support it using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket. Note their orientation for proper installation of the new pads.

4. Install New Brake Pads

Compare the old brake pads with the new ones to ensure correct sizing.
Apply brake lubricant to the back of the new pads to reduce noise.
Install the new brake pads into the caliper bracket in the same orientation as the old ones.

5. Reassemble Brake System

Reposition the caliper over the new brake pads and secure it by tightening the caliper bolts to the manufacturer’s specified torque (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to ensure even tension.
