Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the ignition is off.
Gather necessary tools and replacement parts.
Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, caliper tool (if needed), safety glasses, gloves.

2. Raise the Vehicle

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

3. Remove the Brake Caliper

Locate the caliper bolts and remove them using the appropriate socket.
Carefully slide the caliper off the brake rotor; support it with a bungee cord or hanging device to avoid damaging the brake line.

4. Replace the Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper and bracket for wear; clean with brake cleaner if necessary.
Install the new brake pads into the bracket, ensuring they are oriented correctly.
If necessary, use a caliper tool to compress the caliper piston to accommodate the new pads.

5. Reassemble the Brake System

Slide the caliper back over the new brake pads and rotor.
Reinstall and torque the caliper bolts to the manufacturer’s specifications (typically around 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Tighten the lug nuts to the manufacturer’s specifications (usually in a star pattern to ensure even tightening).
