Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Lift Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect and Replace Brake Rotors

Inspection:
- Remove caliper bolts with a socket set and slide the caliper off the rotor.
- Check the rotor for warping using a dial indicator. If warped beyond specifications (typically 0.002 inches), replace the rotor.
Replacement:
- Remove the old rotor by unscrewing any retaining screws if present.
- Install the new rotor, ensuring it is properly seated and aligned.
- Torque the rotor retaining screws to the manufacturer’s specification.

4. Inspect and Replace Brake Pads

Inspection:
- Remove the brake pads from the caliper bracket.
- Measure the thickness of the pads; replace if below the minimum specification (usually around 3mm).
Replacement:
- Install new brake pads into the caliper bracket.
- Apply anti-squeal lubricant to the back of the pads to reduce noise.

5. Reassemble Braking Components

Reattach the caliper over the new pads and rotor.
Torque caliper bolts to the manufacturer’s specification.
Reinstall the front wheels and lower the vehicle back to the ground.

6. Test Brake System

Reconnect the negative battery terminal.
Pump the brake pedal to ensure proper brake pad seating.
Perform a test drive to check for any remaining shaking or vibrations.
