Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Gather safety gear including gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle.
Secure with jack stands for safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.

4. Inspect and Replace Brake Pads

Remove Caliper:
- Use a socket to remove caliper bolts.
- Carefully slide the caliper off the rotor.
Inspect Brake Pads:
- Check the pads for uneven wear; replace if necessary.
Replace Brake Pads:
- Remove old pads from the caliper bracket.
- Install new pads, ensuring they are properly seated.

5. Check and Replace Calipers (if necessary)

If calipers are found to be sticking, they may need to be replaced.
Remove the brake line from the caliper using a wrench.
Install the new caliper and torque the bolts to manufacturer specifications.

6. Inspect and Replace Rotors (if necessary)

If rotors are warped or below minimum thickness, replace them.
Remove the rotor by unscrewing the retaining screws if present.
Install new rotors and torque to specifications.

7. Reassemble and Test

Reinstall the caliper and secure it with bolts.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to manufacturer specifications.
