Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.

2. Remove Wheels

Use a lug wrench to loosen the lug nuts on the front wheels.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the front wheels.

3. Inspect and Replace Brake Components

Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set.
- Lift the caliper off the rotor and hang it using a bungee cord to avoid stress on the brake line.
- Inspect the brake pads for wear; replace if thickness is less than 3mm.
- Install new pads, ensuring they are properly seated in the caliper bracket.

Brake Rotors

Sub-steps:
- Check the rotors for warping using a dial indicator or by visual inspection for uneven surfaces.
- If warped, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
- Replace with new rotors, ensuring they are clean and free of debris before installation.

Brake Calipers

Sub-steps:
- Inspect caliper pistons for sticking. If they do not retract smoothly, consider rebuilding or replacing the caliper.
- Clean any debris from caliper mounting brackets and lubricate with brake grease.

4. Reassemble and Test

Reattach the caliper over the new pads and rotor, ensuring all bolts are tightened to the manufacturer’s torque specifications (typically around 30-40 Nm).
Reinstall the wheels and lug nuts, tightening them in a star pattern to the recommended torque (typically around 120 Nm).
Lower the vehicle and perform a test drive to ensure proper braking function.
