Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety glasses, gloves.
Park the vehicle on a flat surface, engage the parking brake, and ensure the engine is off.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle depending on which brake pads you are replacing.
Secure the vehicle on jack stands for safety.

3. Remove Wheel

Loosen lug nuts with the lug wrench before lifting.
Remove the lug nuts and take off the wheel to access the brake assembly.

4. Remove Old Brake Pads

Locate the brake caliper and remove the bolts using a socket set.
Carefully slide the caliper off the rotor. Support it with a bungee cord or hanger to prevent stress on the brake line.
Remove the old brake pads from the caliper bracket. Note the position of shims if present.

5. Inspect and Clean

Inspect the brake rotor for wear or damage. Replace if necessary.
Clean the caliper and bracket with brake cleaner to remove dust and debris.

6. Install New Brake Pads

Place the new brake pads into the caliper bracket in the same position as the old ones.
Apply anti-squeal lubricant on the back of the pads if recommended by the manufacturer.
Reinstall the caliper over the new pads and secure with bolts. Torque to manufacturer specifications.

7. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the specified value.
Repeat for other wheels if necessary.
