Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and goggles.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Pads

Inspection:
- Examine brake pads for wear. Replace if they are less than 3mm thick.
Replacement:
- Remove the caliper bolts using a socket set.
- Lift the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for any deep grooves or warping.
If replacement is necessary:
- Remove the caliper bracket bolts and the caliper.
- Remove the rotor from the hub, using a hammer if it's stuck.
- Install the new rotor, ensuring it seats properly on the hub.

5. Reassemble and Lower the Vehicle

Reattach the caliper and caliper bracket, tightening bolts to manufacturer specifications (usually around 25-35 Nm).
Reinstall the wheels and lower the vehicle to the ground.

6. Bleed the Brakes (if applicable)

If brake fluid was lost during the process, bleed the brake lines to remove air bubbles:
- Start with the brake furthest from the master cylinder (usually the passenger rear).
- Use a brake bleeding kit or have an assistant pump the brake pedal while you open and close the bleeder valve.
