Solution

1. Preparation

Gather all necessary tools and parts.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels.

2. Inspect and Replace Brake Rotors

Remove Calipers:
- Use a socket set to remove caliper mounting bolts.
- Hang the caliper using a bungee cord to avoid stressing the brake line.
Remove Brake Rotors:
- If the rotor is secured with retaining screws, remove them.
- Slide the rotor off the hub. If it’s stuck, gently tap with a rubber mallet.
Inspect Rotors:
- Check for warping using a dial indicator or visual inspection.
- Replace rotors if there is significant warping (over 0.002 inches).
Install New Rotors:
- Place the new rotor onto the hub.
- Reinstall retaining screws if applicable.

3. Inspect and Replace Brake Pads

Remove Old Pads:
- Remove the caliper bracket if needed.
- Slide out the old brake pads from the caliper bracket.
Install New Pads:
- Apply brake grease to the back of the new pads.
- Insert the new pads into the caliper bracket.
Reattach Calipers:
- Position the caliper over the new pads and reinstall mounting bolts.
- Torque the bolts to the manufacturer’s specifications (typically 20-25 ft-lbs).

4. Check Suspension Components

Inspect Struts and Bushings:
- Look for any signs of wear or damage.
- Replace any worn components as necessary.
Check Wheel Bearings:
- Rotate the hub to listen for any grinding noises.
- Replace bearings if they exhibit excessive play or noise.

5. Wheel Alignment

Perform Wheel Alignment:
- Take the vehicle to a professional alignment shop.
- Ensure alignment settings are within manufacturer specifications.

Tools Required:

Socket set
Torque wrench
Brake cleaner
Bungee cord or hanging strap
Rubber mallet
Dial indicator (for rotor inspection)
Brake grease

Parts Required:

Brake rotors (if warped)
Brake pads (if worn)
Wheel bearings (if damaged)
Suspension components (if worn)

Estimated Repair Time: 2-4 hours

Safety Warnings:
