Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, OBD-II scanner, torque wrench.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent any electrical shorts during inspection.

2. Inspect Brake Components

Lift the Vehicle: Use a jack to elevate the vehicle and secure it with jack stands.
Remove Wheels: Use the lug wrench to take off the wheels to access the brake components.
Check Brake Pads: Inspect pads for thickness; replace if below manufacturer specifications.
Examine Rotors: Use a caliper gauge to measure rotor thickness and check for warping. If warped, resurface or replace as needed.
Inspect Calipers: Ensure calipers move freely; check for leaks and proper operation.

3. Replace Components if Necessary

Brake Pad Replacement:
- Remove the caliper bolts and slide the caliper off the rotor.
- Replace old pads with new ones, ensuring they are properly seated.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically around 25-30 ft-lbs).
Rotor Replacement:
- If rotors are damaged, remove them by unbolting the caliper bracket.
- Install new rotors, ensuring they are clean and free from grease.
- Reinstall the caliper bracket and torque the bolts appropriately (typically around 75-85 ft-lbs).

4. Reassemble and Test

Reinstall Wheels: Place wheels back on and hand-tighten the lug nuts.
Lower Vehicle: Carefully remove jack stands and lower the vehicle back to the ground.
Torque Lug Nuts: Use a torque wrench to tighten lug nuts to the manufacturer’s specifications (typically around 75-80 ft-lbs).
Reconnect Battery: Reconnect the battery and ensure all electrical connections are secure.
