Solution

1. Preparation

Ensure the vehicle is parked on a level surface and engaged in gear or park.
Gather necessary tools and parts.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety glasses, gloves.

2. Raise the Vehicle

Use a jack to lift the vehicle and securely place it on jack stands.
Remove the wheels using a lug wrench.

3. Remove Brake Components

Brake Pads:
- Locate the brake caliper and remove the caliper bolts using a socket.
- Carefully slide the caliper off the rotor and support it with a bungee cord or similar.
- Remove the old brake pads from the caliper bracket.
Brake Rotors (if needed):
- If replacing rotors, remove the caliper bracket bolts and slide the bracket off.
- Remove the rotor by pulling it straight off the hub, ensuring any retaining screws are removed.

4. Inspect and Clean

Inspect the caliper for damage or leaks.
Clean the rotor surface with brake cleaner to remove any debris or grease.
If the rotor is not being replaced, ensure it's smooth and free from scoring.

5. Install New Components

New Brake Pads:
- Apply brake grease to the back of the new brake pads to prevent squeaking.
- Install the new pads into the caliper bracket.
New Rotors (if applicable):
- Install the new rotor onto the hub and secure it with retaining screws if applicable.
- Reattach the caliper bracket over the new pads and torque bolts to manufacturer specifications.

6. Reassemble and Test

Reinstall the brake caliper over the new pads and torque the caliper bolts to the manufacturer’s specifications.
Reattach the wheels and torque the lug nuts in a crisscross pattern.
Lower the vehicle from the jack stands.
