Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, socket set.

2. Remove Wheels

Loosen lug nuts slightly before lifting the vehicle.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheels.

3. Inspect and Replace Brake Rotors

Inspection:
- Use a dial indicator to measure rotor runout. If it exceeds manufacturer specifications, it needs replacement.
Replacement:
- Remove the caliper by unbolting it and hanging it securely (do not let it hang by the brake line).
- Remove the rotor by unbolting and sliding it off the hub.
- Install new rotors, ensuring they are properly seated.
- Torque Specification: Refer to the service manual for proper torque values on the rotor bolts.

4. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if less than 3mm, replace them.
Remove the old pads from the caliper bracket.
Install new brake pads, ensuring they are correctly positioned.
Apply brake grease to the backing of the pads to prevent squeaking.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the bolts to specification.
Reattach the wheels and torque the lug nuts in a star pattern to the manufacturer's specifications.
Lower the vehicle and perform a brake test at low speed to ensure proper operation.
