Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Wear safety gloves and goggles for protection.

2. Lift Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the brake issue is present.
Secure the vehicle with jack stands.

3. Remove Wheel

Using a socket set, remove the lug nuts and take off the wheel to access the brakes.

4. Inspect and Replace Brake Pads

Inspect for wear: Check the brake pads for uneven wear, and measure thickness.
Remove old pads: Unbolt the caliper from the bracket and slide it off the rotor. Remove the old brake pads from the caliper bracket.
Clean components: Clean the caliper bracket, rotor, and surrounding area with brake cleaner.
Install new pads: Place new brake pads into the caliper bracket. Ensure they are seated properly.

5. Check and Replace Calipers (if necessary)

Inspect calipers: If calipers are sticking or damaged, replace them.
Remove caliper: Unbolt the caliper from the bracket and disconnect the brake line.
Install new caliper: Attach the new caliper in place, ensuring it is secured and the brake line is connected without leaks.

6. Reassemble and Test

Reattach the caliper and ensure all bolts are tightened to manufacturer specifications (typically 25-30 ft-lbs).
Reinstall the wheel and lug nuts, tightening in a star pattern.
Lower the vehicle, and pump the brake pedal to seat the pads against the rotor.
