Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Raise the Vehicle

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

3. Remove Wheel

Use a lug wrench to loosen and remove wheel lug nuts.
Take off the wheel to access the brake assembly.

4. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it without stressing the brake line.
Remove the old brake pads from the caliper bracket.
Inspect for any debris or dust; clean the caliper bracket if necessary.
Install new brake pads, ensuring they are properly aligned.

5. Inspect and Replace Brake Rotors (if needed)

Check the rotor for damage; if it is scored or warped, it must be replaced.
Remove the rotor from the hub by unscrewing any retaining screws, if applicable.
Install new rotors, ensuring they are properly seated.

6. Reassemble Components

Reattach the caliper over the new brake pads and torque the caliper bolts to the manufacturer's specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle and Test

Lower the vehicle from the jack stands and remove the jack.
Tighten the lug nuts to the specified torque (typically 80-100 ft-lbs).
Test the brakes by pressing the pedal multiple times to seat the pads.
