Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface with the engine off.
Gather safety equipment (gloves, goggles).

2. Lift Vehicle

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

3. Remove Wheel

Use a socket set to remove the lug nuts.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspection:
- Remove the caliper bolts using the appropriate socket.
- Gently slide the caliper off the rotor.
- Inspect brake pads for thickness (less than 3mm indicates replacement).
Replacement:
- If worn, remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated correctly.
- Apply brake grease to the backing of the pads to reduce noise.

5. Inspect and Replace Brake Rotors

Check the rotors for signs of damage or excessive wear.
If replacement is needed, remove the caliper bracket and rotor.
Install new rotors, ensuring they are properly aligned and torqued to manufacturer's specifications.

6. Reassemble Components

Reattach the caliper and secure it with bolts.
Reinstall the wheel and tighten lug nuts in a crisscross pattern to the specified torque.
Lower the vehicle back to the ground.

7. Brake Fluid Check

Inspect the brake fluid level and top off with manufacturer-recommended fluid if necessary.
