Solution

1. Preparation

Tools Required: Floor jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner, safety glasses, gloves.
Ensure vehicle is on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Raise Vehicle and Remove Wheels

Use a floor jack to lift the vehicle and secure it with jack stands.
Remove the wheels using a lug wrench.

3. Inspect and Replace Brake Rotors

Sub-steps:
- Measure rotor runout with a dial indicator; if warping exceeds manufacturer specifications, replace rotors.
- Remove caliper bolts and carefully detach the caliper; support it without stretching the brake line.
- Remove the rotor by unscrewing the retaining screws or pulling it off the hub.
- Install new rotors, ensuring they are torqued to the manufacturer’s specifications.

4. Inspect and Replace Brake Pads

Sub-steps:
- Check brake pads for thickness and wear; replace if below the minimum thickness.
- Clean the caliper bracket and apply brake grease to the backing of the new pads.
- Install new brake pads, ensuring they seat properly within the caliper.

5. Reassemble and Lower Vehicle

Reattach the caliper and torque bolts to manufacturer specifications.
Reinstall wheels and torque lug nuts in a star pattern to the specified torque.
Lower the vehicle and reconnect the negative battery terminal.
