Solution

1. Preparation

Gather necessary tools and park the vehicle on a level surface.
Ensure the vehicle is securely lifted using jack stands.
Disconnect the battery if working on electronic brake components.

2. Inspect and Replace Brake Rotors

Remove Wheel
- Use a socket set to remove lug nuts and take off the wheel.
Inspect Rotors
- Measure rotor thickness and check for warping with a dial indicator.
- If rotors are warped beyond specifications (generally over 0.002 inches), proceed to replace.
Remove Calipers and Rotors
- Use a socket set to remove caliper bolts and detach calipers from the rotor.
- Suspend calipers using a bungee cord to avoid strain on brake lines.
- Remove the rotor by unscrewing any retaining screws and pulling it off.
Install New Rotors
- Clean hub surface and install new rotors. Torque retaining screws to manufacturer specifications (typically 10-15 ft-lbs).

3. Replace Brake Pads

Remove Old Pads
- Remove the old brake pads from the caliper bracket.
Install New Pads
- Apply brake grease to the backing of new pads and install them into the caliper bracket.
Reattach Calipers
- Reposition the calipers over the new pads and secure them with caliper bolts. Torque them to manufacturer specifications (typically around 20-25 ft-lbs).

4. Suspension Inspection and Repair (if necessary)

Inspect Components
- Check ball joints and tie rod ends for play. Replace any worn or damaged parts.
Alignment Check
- After repairs, ensure the vehicle is aligned. Adjust as necessary.
