Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, dial indicator, measuring calipers, safety glasses, gloves.
Safely raise the vehicle and secure it on jack stands. Remove the wheel using the lug wrench.

2. Inspect and Replace Brake Rotors

Inspect Rotors: Use a dial indicator to measure rotor runout. If over 0.002 inches, the rotors may need replacement.
Remove Caliper: Use a socket to remove the caliper bolts. Hang the caliper using a bungee cord to avoid stress on the brake line.
Remove Rotor: If rotors are held by retaining screws, remove them and slide the rotor off. Clean the hub surface with brake cleaner.
Install New Rotor: Place the new rotor onto the hub, ensuring it sits flush. Reinstall any retaining screws if applicable.

3. Inspect and Replace Brake Pads

Remove Old Pads: Remove the caliper bracket bolts and then take out the brake pads. Inspect for even wear.
Install New Pads: Apply brake grease to the back of new pads to prevent squeaking. Install new pads into the caliper bracket.

4. Reassemble Brakes

Reattach Caliper: Position the caliper over the new pads and secure it with the caliper bolts. Torque to manufacturer specifications (usually around 20-25 Nm).
Reinstall Wheel: Place the wheel back on, hand-tighten the lug nuts, lower the vehicle, and then torque the lug nuts to the specified value (typically around 100 Nm).
