Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid electrical issues while working on the braking system.

2. Inspect and Replace Brake Rotors

Remove Wheel:
- Use a lug wrench to loosen the lug nuts.
- Lift the vehicle using a floor jack and secure with jack stands.
- Completely remove the lug nuts and wheel.
Remove Brake Caliper:
- Loosen the bolts securing the brake caliper using a socket set.
- Carefully slide the caliper off the rotor and support it using a bungee cord to avoid straining the brake line.
Remove Brake Rotor:
- If the rotor is held by retaining screws, remove them with a screwdriver.
- Slide the rotor off the hub; if it is stuck, gently tap it with a rubber mallet.
Install New Rotor:
- Place the new rotor onto the hub, ensuring it's properly seated.
- Reinstall any retaining screws if applicable.

3. Inspect and Replace Brake Pads

Remove Old Brake Pads:
- Locate the brake pads within the caliper bracket.
- Slide out the old pads, noting their orientation for the installation of new ones.
Install New Brake Pads:
- Apply brake grease to the backing of the new pads to prevent squeaking.
- Slide the new pads into the caliper bracket in the same position as the old ones.

4. Reassemble and Test

Reinstall Brake Caliper:
- Position the caliper over the new pads and rotor.
- Tighten the caliper bolts to the manufacturer’s specified torque value (usually around 20-25 ft-lbs).
Reinstall Wheel:
- Place the wheel back onto the hub.
- Hand-tighten the lug nuts before lowering the vehicle.
Lower Vehicle:
- Remove jack stands and lower the vehicle back to the ground.
Reconnect Battery:
- Reconnect the negative battery terminal.
