Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Front Wheels

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove lug nuts using a socket wrench and take off the front wheels.

3. Inspect and Replace Brake Rotors

Inspection:
- Check the brake rotors for warping or uneven wear.
- Measure rotor thickness with a micrometer; if below specifications, replace.
Replacement:
- Remove caliper bolts and lift the caliper off the rotor.
- Hang the caliper using a wire to prevent strain on the brake line.
- Remove the old rotor; clean the hub surface of any rust or debris.
- Install the new rotor, ensuring it is seated properly.
- Reinstall the caliper and torque bolts to manufacturer specifications (usually around 20-25 lb-ft).

4. Check and Replace Brake Pads

Inspect brake pads for wear. If they are worn below the minimum thickness, replace them.
Remove the caliper bracket if necessary, then slide out the old pads.
Install new pads, ensuring proper alignment and fitment.
Reinstall the caliper bracket and torque to manufacturer specifications.

5. Wheel Alignment and Suspension Check

Check suspension components (tie rods, ball joints) for wear or damage.
Ensure the alignment is within specifications; adjust if necessary.

6. Reinstall Front Wheels

Place wheels back on the hubs, hand-tightening the lug nuts.
Lower the vehicle and then torque the lug nuts to manufacturer specifications (typically 80-100 lb-ft).
