Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety glasses and gloves.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on the affected brakes.
Secure the vehicle with jack stands.

3. Remove Wheels

Use a lug wrench to remove the lug nuts and take off the wheels.
Ensure lug nuts are stored safely for reinstallation.

4. Inspect and Replace Brake Pads

Inspect: Check brake pad thickness; if below 3mm, replace.
Remove: Unbolt the caliper using a socket set and carefully slide it off the rotor.
Replace: Remove old brake pads and install new ones, ensuring they are aligned properly.
Tools Required: Socket set, torque wrench.

5. Inspect and Replace Brake Rotors (if necessary)

Inspect: Check rotors for any visible damage or wear.
Remove: Unbolt the rotor using a socket set, if it appears worn or damaged.
Replace: Install new rotors, ensuring they are seated properly.
Tools Required: Socket set, torque wrench.

6. Reassemble and Lower Vehicle

Reattach the caliper over the new brake pads, ensuring it’s secure.
Reinstall the wheel and lug nuts, tightening to manufacturer specifications.
Lower the vehicle to the ground.

7. Bleed Brake System (if necessary)

If brake fluid was lost, bleed the brake system using a brake bleeder kit.
Ensure there are no air bubbles in the brake lines.
