Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, socket set, brake cleaner, and safety glasses.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Wear safety glasses to protect your eyes.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts on the wheels.
Jack up the vehicle using the jack and secure it with jack stands.
Remove the lug nuts and wheels to access the brakes.

3. Inspect and Remove Brake Components

Brake Pads:
- Check the thickness of the brake pads. If they are less than 3mm, they should be replaced.
- Remove the caliper bolts using a socket set and slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
Brake Rotors:
- Inspect the rotors for grooves or scoring. If damaged, they should be replaced or resurfaced.
- Remove the rotor by unscrewing any retaining screws or bolts, if present.

4. Install New Components

New Brake Pads:
- Apply brake lubricant to the back of the new brake pads to prevent squeaking.
- Install the new brake pads into the caliper bracket.
New Brake Rotors:
- If replacing, install the new rotors onto the hub.
- Secure using retaining screws or bolts if applicable.

5. Reassemble Brake Components

Reinstall the caliper over the new pads and rotor, ensuring it seats correctly.
Tighten the caliper bolts to the manufacturer's specified torque settings.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle and Test

Lower the vehicle back to the ground using the jack.
Tighten the lug nuts to the manufacturer's specified torque settings.
Pump the brake pedal a few times to seat the pads against the rotors.
Test drive the vehicle at low speeds to ensure the issue is resolved.
