Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Lift Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which brakes are affected.
Support the vehicle with jack stands for safety.

3. Inspect and Replace Brake Rotors

Remove Wheel:
- Use a lug wrench to loosen and remove the lug nuts.
- Take off the wheel and set aside.
Remove Brake Caliper:
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor.
- Support it with a bungee cord to avoid hanging from the brake line.
Remove Brake Rotor:
- If the rotor is held by retaining screws, remove them.
- Slide the rotor off the hub. If it’s stuck, gently tap with a rubber mallet.
Install New Rotor:
- Clean the hub surface with a wire brush if necessary.
- Position the new rotor onto the hub.
- Secure with any retaining screws if applicable.

4. Inspect and Replace Brake Pads

Remove Old Brake Pads:
- Remove the caliper bracket if necessary.
- Slide out the old brake pads from the caliper bracket.
Install New Brake Pads:
- Apply brake grease to the contact points of the new pads.
- Install the new pads into the caliper bracket.

5. Reassemble Brake Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper mounting bolts to manufacturer specifications (usually around 25-35 Nm).
Reinstall the wheel and tighten lug nuts in a star pattern to ensure even pressure.

6. Lower Vehicle and Test

Carefully lower the vehicle off the jack stands.
Pump the brake pedal several times to ensure proper brake engagement.
Perform a test drive to verify the repair.
