Solution

1. Preparation

Gather tools and parts: jack, jack stands, wheel chocks, lug wrench, brake cleaner, dial indicator, torque wrench.
Ensure the vehicle is on a level surface and the engine is off.
Disconnect the battery (optional but recommended for safety).

2. Inspect and Replace Brake Rotors

Lift the Vehicle
- Use a jack to lift the front or rear of the vehicle.
- Secure with jack stands and place wheel chocks behind the opposite wheels.
Remove Wheels
- Loosen and remove the lug nuts with a lug wrench.
- Take off the wheel to access brake components.
Measure Rotor Thickness
- Use a dial indicator to measure rotor thickness at multiple points.
- If thickness is inconsistent or below specifications, replace the rotors.
Remove Old Rotors
- Unscrew the caliper bracket bolts and remove the caliper.
- Slide the rotor off the hub.
Install New Rotors
- Clean the new rotors with brake cleaner to remove protective coatings.
- Install the new rotor onto the hub.
Reinstall Caliper and Wheel
- Reattach the caliper and torque bolts to the manufacturer's specifications.
- Place the wheel back on and hand-tighten the lug nuts.

3. Replace Brake Pads

Remove Old Brake Pads
- With the caliper still off, remove the old brake pads from the caliper bracket.
Check Caliper Piston
- Push the caliper piston back using a C-clamp to make room for new pads.
Install New Brake Pads
- Place new pads into the caliper bracket, ensuring proper alignment.
Reattach Caliper
- Position the caliper back over the pads and torque bolts to specifications.

4. Inspect Suspension Components

Visual Inspection
- Check control arms, bushings, and tie rod ends for excessive wear or damage.
Replace Worn Components
- If any components are found to be worn, replace them according to manufacturer specifications.
