Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety equipment such as gloves and goggles.

2. Lift the Vehicle

Loosen the lug nuts on the front wheels slightly while the vehicle is still on the ground.
Use a hydraulic jack to lift the front of the vehicle and place jack stands for safety.
Remove the front wheels to access the brake assembly.

3. Remove the Brake Caliper

Locate the caliper mounting bolts (usually two bolts).
Use a socket wrench to remove the caliper bolts and carefully slide the caliper off the brake rotor.
Support the caliper using a bungee cord or rope to prevent strain on the brake line.

4. Remove Old Brake Pads

Slide the old brake pads out of the caliper bracket. Note the orientation for installation of new pads.
Inspect the caliper bracket for any debris or rust and clean if necessary.

5. Install New Brake Pads

Apply a thin layer of brake grease to the back of the new brake pads to prevent squeaking.
Insert the new brake pads into the caliper bracket in the same orientation as the old ones.

6. Reinstall the Brake Caliper

Compress the caliper piston using a brake caliper tool or a C-clamp to make room for the new pads.
Slide the caliper back over the new brake pads and secure it with the caliper mounting bolts. Torque the bolts to the manufacturer’s specifications (usually around 85 ft-lbs).

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands using the hydraulic jack.
Once the vehicle is on the ground, fully tighten the lug nuts in a crisscross pattern to the manufacturer’s torque specifications (typically around 76 ft-lbs).

8. Final Checks

Pump the brake pedal a few times to ensure proper caliper engagement and brake pressure.
Check brake fluid levels and top off if necessary.
