Solution

1. Preparation

Tools Required: OBD-II scanner, micrometer, jack and jack stands, tire iron, brake cleaner, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical components. Allow the brakes to cool before inspection.

2. Brake Pad Replacement

Lift the Vehicle: Use a jack to raise the vehicle and secure it with jack stands.
Remove Wheels: Use a tire iron to loosen and remove the lug nuts from the wheels.
Remove Calipers:
- Remove the caliper mounting bolts using the appropriate socket.
- Carefully slide the caliper off the rotor and support it with a bungee cord or rope to avoid strain on the brake line.
Replace Brake Pads:
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket with brake cleaner.
- Install new brake pads, ensuring they are seated properly.
Reassemble Calipers:
- Reposition the caliper over the new brake pads and secure it with mounting bolts. Torque the bolts to manufacturer specifications.

3. Brake Rotor Replacement (if necessary)

Remove Rotors:
- If the rotors are warped or damaged, remove them by unscrewing the retaining screws (if present) and sliding them off the hub.
Install New Rotors:
- Clean the new rotors with brake cleaner to remove any protective oil.
- Slide the new rotor onto the hub and secure it with screws.
Reassemble Wheels:
- Place the wheels back onto the vehicle and hand-tighten the lug nuts before lowering the vehicle.

4. Brake Fluid Change (if contaminated)

Locate Brake Fluid Reservoir: Open the hood and locate the brake fluid reservoir.
Remove Old Fluid:
- Use a turkey baster or siphon to remove old brake fluid from the reservoir.
Add New Brake Fluid:
- Fill the reservoir with fresh brake fluid that meets manufacturer's specifications.
