Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during work.

2. Inspect and Replace Brake Rotors

Remove the Wheel
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts with a socket set and take off the wheel.
Inspect Rotors
- Use a dial indicator to check for warping; replace if runout exceeds manufacturer's specifications.
- Clean the rotor surface with brake cleaner and inspect for cracks or deep grooves.
Replace Rotors (if necessary)
- Remove caliper bolts with a socket wrench and slide off the caliper.
- Remove the old rotor by unbolting it from the hub and replace it with a new one.
- Torque rotor bolts to specification.

3. Replace Brake Pads

Remove Old Brake Pads
- Slide off the caliper and remove the old pads.
- Note the orientation and position of the pads for installation.
Install New Brake Pads
- Place new brake pads in the caliper bracket, ensuring proper alignment.
- Apply brake grease to the backing of the pads to prevent squeaking.
Reattach Caliper
- Reinstall the caliper over the new pads and secure it with bolts, torquing to specification.

4. Reassemble and Test

Reinstall the Wheel
- Place the wheel back on and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Reconnect Battery
- Reconnect the negative battery terminal.
Test Drive
- Conduct a test drive to check for vibrations and ensure brakes function properly.
