Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, C-clamp or brake caliper tool, brake cleaner, bungee cord or rope.
Safety Warnings:
- Always engage the parking brake.
- Wear safety goggles and gloves.
- Ensure the vehicle is on a flat surface.

2. Lift the Vehicle

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and remove them using a socket.
Carefully slide the caliper off the rotor.
Use a bungee cord to hang the caliper from the suspension to avoid stress on the brake line.

4. Replace the Brake Pads

Remove the old brake pads from the caliper bracket.
If applicable, replace any worn shims or clips.
Apply a thin layer of brake grease to the back of the new brake pads.
Install the new brake pads into the caliper bracket.

5. Reinstall the Brake Caliper

Use a C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing.
Slide the caliper back over the new pads and align it with the mounting holes.
Reinstall and tighten the caliper mounting bolts to the manufacturer’s torque specification (typically around 25-30 ft-lbs).

6. Reassemble the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Tighten the lug nuts in a crisscross pattern to the manufacturer’s specification (typically around 80-100 ft-lbs).

7. Test the Brakes

Before driving, pump the brake pedal a few times to ensure proper brake pad seating.
Check for any unusual noises or issues during a low-speed test drive.
