Solution

1. Preparation

Gather tools and necessary parts for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Raise the Vehicle

Use a jack to lift the front of the vehicle.
Secure with jack stands to ensure safety.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Inspect the brake components visually.

4. Inspect and Replace Brake Rotors

Check the rotor surfaces for warping or damage.
- If warped, proceed to replace:
  - Remove caliper bolts using a socket set.
  - Lift the caliper off and hang it using a wire hook or bungee cord (do not let it dangle on the brake line).
  - Remove the rotor retaining screws if applicable.
  - Slide off the old rotor.
  - Install the new rotor, ensuring it is seated properly.
  - Reattach the caliper and torque bolts to manufacturer specifications (typically around 30-40 Nm, check specific values).

5. Replace Brake Pads

Remove old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads, ensuring proper orientation.
Reassemble caliper over new pads and torque bolts.

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from jack stands and fully tighten lug nuts in a star pattern to the manufacturer’s specified torque (usually 100-120 Nm).
