Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake pad spreader or C-clamp, torque wrench, brake cleaner, and safety glasses.
Park the vehicle on a level surface, turn off the ignition, and engage the parking brake.
Wear safety glasses to protect your eyes.

2. Lift the Vehicle

Loosen the lug nuts on the front or rear wheels slightly (do not remove).
Use a jack to lift the vehicle and then secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts (usually two bolts).
Use the appropriate socket to remove the caliper bolts.
Carefully slide the caliper off the rotor and hang it using a bungee cord or cable tie (do not let it hang by the brake line).

4. Remove the Old Brake Pads

Slide the old brake pads out of the caliper bracket.
Inspect the caliper bracket; clean if necessary with brake cleaner.

5. Install New Brake Pads

Apply a thin layer of brake grease to the back of the new brake pads (avoid getting grease on the friction surface).
Slide the new brake pads into the caliper bracket, ensuring they are properly seated.

6. Reinstall the Brake Caliper

Use the brake caliper spreader or C-clamp to compress the caliper piston if it does not fit over the new pads.
Position the caliper back over the new pads and align the mounting holes.
Reinstall and tighten the caliper bolts to the manufacturer's specified torque (typically around 25-30 ft-lbs).

7. Reassemble the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts in a crisscross pattern to the manufacturer's specified torque (typically around 76 ft-lbs).

8. Final Steps

Pump the brake pedal a few times to seat the pads against the rotor.
Check the brake fluid level and top off if necessary.
Dispose of old brake pads according to local regulations.
