Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to ensure safety during the repair.

2. Raise the Vehicle

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

3. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and inspect the brake pads for wear.
Replacement:
- If worn, replace the brake pads with new ones.
- Apply brake grease to the backing of the new pads to prevent noise.
- Reinstall the caliper and torque the bolts to the manufacturer’s specifications (typically around 25-30 Nm).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are warped or scored:
- Remove the rotor by removing the retaining screws and sliding it off the hub.
- Clean the hub surface to remove debris and rust.
- Install new rotors, ensuring they are properly aligned.
- Torque the retaining screws to the manufacturer's specifications (typically around 10-15 Nm).

5. Reassemble and Test

Reinstall the wheels and lower the vehicle back to the ground.
Reconnect the battery.
Pump the brake pedal several times to ensure proper brake pad seating.
