Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the braking system.

2. Remove Wheel

Loosen lug nuts while the car is still on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the braking components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor and suspend it with a bungee cord or wire to avoid stressing the brake line.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and inspect for any debris or corrosion.
Install new brake pads, ensuring they are seated properly in the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Inspect the new rotor for any protective coating and clean it with brake cleaner.
Install the new rotor onto the hub, ensuring it is seated correctly.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications (check service manual for specific torque values).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque setting.

6. Final Checks

Reconnect the battery.
Press the brake pedal a few times to ensure the pads seat properly against the rotor.
Check the brake fluid level and add fluid if necessary.
