Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the parking brake engaged.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the brake components.

3. Inspect and Replace Brake Rotors

Check Rotor Condition:
- Use a run-out gauge to measure rotor warpage; if warped beyond specifications, replace.
Remove Calipers:
- Unbolt the caliper from its bracket using a socket set.
- Support the caliper with wire or a bungee cord, do not let it hang by the brake line.
Remove Rotors:
- If needed, remove any retaining screws and slide the rotors off the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove protective oil.
- Install the new rotors and secure with retaining screws if applicable.

4. Inspect and Replace Brake Pads

Remove Old Brake Pads:
- Slide out the old pads from the caliper bracket.
Install New Brake Pads:
- Apply a thin layer of brake grease on the back of the new pads to prevent noise.
- Insert the new pads into the caliper bracket.

5. Reassemble and Bleed Brakes

Reattach Calipers:
- Bolt the caliper back onto the bracket and torque to the manufacturer’s specifications.
Bleed the Brake System:
- Begin at the farthest wheel from the master cylinder, using a brake bleeder kit to remove any air in the system.

6. Lower the Vehicle and Test

Remove jack stands and lower the vehicle.
Test the brake pedal feel before driving.
